AI breakthrough in Tassie salmon farming

Established in 1986, Huon Aquaculture has grown to become a salmon producer that is recognised around the world for the quality of its produce and the ingenuity of its operations.

The company is seen as an ethical business and a respected Tasmanian brand — part of a sustainable industry and a company that is focused on the safety of its employees, as well as the welfare of the fish and the wildlife around its farms.

Huon Aquaculture is fortunate to farm in Tasmania’s healthy marine environment, allowing them to raise salmon and ocean trout in locations best suited to optimal growth. From the time their fish start their life in hatcheries, up until they are harvested, their environment plays a vital role in their health, growth and quality.

Huon is a fully vertically integrated company, meaning that the company does everything from selectively breeding brood stock for egg production, to processing salmon ready for the consumer.

Rough conditions in Storm Bay

Huon’s Storm Bay lease has the roughest farmable waters in the world. Located at the mouth of Tasmania’s Derwent River and opening south towards the wild Southern Ocean, Storm Bay can regularly experience swells of 4–6 metres significant wave height. While these conditions can be dangerous for people, Huon has found that the swells regularly rolling through the pens is good for the fish as it closely mimics their natural habitat. It also means that the pens can be left fallow for a shorter time before restocking.

However, the rough seas are also one of the reasons that Huon embarked on a journey to find a way to reduce or eliminate the need for people to be manually operating feed barges in such rough and dangerous conditions. Huon looked into mirroring what companies were doing around the world, where they were controlling their processes from a centralised location.

Consistency of yield depends on consistency of feeding

A major reason for automating fish feeding is the desire to maximise the consistency of the size and weight of the salmon at harvesting. Huon’s pens are, according to Peter Bender, Chief Executive Officer and Managing Director, the largest ocean fish pens in the world, with circumferences of around 240 metres and holding over 100,000 fish. With manual feeding, there can be days when fish are fed less and days when they are overfed — and uneaten fish pellets fall to the ocean floor, which is not only wasteful, but pollutes the ocean floor environment.

Moreover, without an even distribution of feed, the result can be an inconsistency in fish size, as the larger fish continue to dominate and consume the most, while others remain small.

No out-of-the-box solution

As a result, Bender went to an exhibition in Europe, only to realise that none of the software displayed was going to be fit for purpose for Huon because of the way they feed and their stocking densities. Many of the systems were designed for feed pens close to shore, and not up to 50 km out to sea, exposed to the Southern Ocean.

The company realised that an out-of-the-box program was not going to meet their needs, so they knew they had to work from the ground up. The company’s aims were to:

move to a centralised control platform that would reduce man-hours out on the water and on the barges, improving personnel safety;

achieve better control over feeding the salmon from the barges;

develop innovation in aquafarming;

have a positive environmental impact in reducing waste with controlled feeding.

The challenge was therefore to develop new technology and implement it on a larger barge that could be moored at sea for longer periods without replenishment.

Enter Hogan, the automated feed barge

Commissioned and launched in December 2018 by Tasmanian shipbuilder Crisp Bros. & Haywards, Hogan is the first of two 600-tonne feed barges that will be used to manage the pens in Storm Bay. The sheer size of the barge is a result of it needing to not only withstand the sea conditions in Storm Bay, but also to remain autonomous for larger periods of time — both for feeding and waste recovery activities.

The significance of the barge is not so much due to its size, however, but due to its technology. Those staff that were once fish feeders are now control room operators and feed every fish in every pen from a control room in Hobart. They are able to do this as each pen has cameras that send real-time footage and data back via the barge to the control room. A pellet detection system that utilises artificial intelligence coupled with a remote controlled on-water feed delivery system makes feed delivery more effective than previous manual feeding.

The pellet detection system can detect as few as two uneaten feed pellets in the water column beneath the fish, and can automatically slow or shut off the flow of feed when the fish have stopped feeding — matching the feeding to the appetite of the fish while reducing wastage and potential impact to the sea floor.

In addition to the pellet detection system, Huon also developed a feed delivery system that spreads the feed evenly across the surface of the pen, by effectively ‘spraying’ it from a central point. This ensures that the fish have an equal chance of receiving feed — resulting in a consistent 5 kg fish size at harvesting.

Harsh conditions require tough hardware

For the control system on the barge, Huon engaged Cromarty Pty Ltd, a specialist automation system engineering and design firm. Cromarty provided all the electrical and control system design. The design work was done over an 18-month period.

“When we were asked to get involved in the building of the barges, it was identified that there wasn’t a proper specification of the valves to be used for the various processes on the vessel,” said Andrew Palfreyman of Cromarty. “Basically the valves chosen were not up to the task of working reliably in the harsh and corrosive conditions expected.”

Andrew encouraged Haywards to contact Katherine George, Managing Director of Total Instrument Controls, to assist in specifying the right type of valves to be used in the elements of the Southern Ocean.

Total Instrument Controls are a supplier of instrumentation and control technology and are one of the leading Australian resellers of Bürkert’s valve systems and controls. Previously the company had supplied Huon Aquaculture with various Bürkert equipment for their hatcheries, including solenoid valves and actuators, as well as oxygen dosing systems.

“The various valves from Bürkert that we supplied for the project have a variety of tasks from moving fluids (air, water, fuel etc) around the barge, as well as controlling the feed spreader systems, deck wash systems and generator fuel shut-offs,” Katherine George said. “Any valves in contact with salt water use a particular grade of stainless steel called Duplex for the trim material, as it provides the best corrosion resistance.”

“Bürkert’s 3005 actuators with battery backup on top of butterfly valves and stainless steel ball valves were chosen. Battery backup was chosen to implement failsafe functionality in case of power loss or loss of communication to the barge,” he added. “Battery backup was a must as many of the valves have the potential to sink the barge in stormy weather if they are stuck open, allowing the seawater to continue to enter the vessel.”

AI the crowning achievement

The huge barge, the remote control and the innovative feed system are all achievements that Huon Aquaculture and its suppliers can be proud of. But the crowning achievement is possibly the artificial intelligence and machine learning that has been incorporated into the control system.

Rather than relying on human operators observing the video feed, as is done in European systems, Huon has a achieved a system that uses the latest in AI and machine learning to automatically respond to fish behaviour, and can ‘learn on the job’. Managing Director Peter Bender believes the system may well be the first of its kind in the world — a world-leading innovation built on Tasmanian ingenuity.

New York, New York

1: 20 AM ET

Tim Bontemps ESPN

New York City– Black Friday provided NBA fans in the Big Apple an uncommon treat: the possibility to take in two video games in one day.

In Between the Boston Celtics and Brooklyn Internet playing at Barclays Center on Friday afternoon and the Philadelphia 76 ers and New York City Knicks squaring off at Madison Square Garden on Friday night, fans might– if they chose– take in four of the five Atlantic Department teams merely by taking a fast subway ride.

We did simply that– and, at the same time, got a chance to take a picture look at all 4 of them as the NBA season is 20%total. Here’s what we saw:

In the middle of a timeout during the Celtics-Nets game, Kevin Durant and Kyrie Irving based on the court laughing and joking with one another

Regrettably for the Webs, though, they did so wearing match coats and slacks.

However while Durant, Irving and Caris LeVert continue to remain with injuries, Brooklyn made a 112-107 triumph over Boston thanks to standout showings from Spencer Dinwiddie and Jarrett Allen— the kind that allow the Webs to hope they can continue their recent hot streak once they begin to get their big names back on the court.

The Internet are now 6-2 without Irving after Friday’s win– a stretch throughout which Dinwiddie has taken on the obstacle of being the group’s lead playmaker with aplomb.

” Simply continuing to advance every year,” stated Dinwiddie, who had 32 points and 11 assists Friday and is balancing 24.5 points and 7.8 assists given that Irving left the lineup. “I was just attempting to strike a balance tonight in between death and scoring and determine my role as it continues to shift around when we get healthy and aren’t hurt.”

Dinwiddie has actually played together with Irving plenty so far this season, too– just as he did together with D’Angelo Russell last season– which will continue as soon as Irving returns. Dinwiddie’s size and length at 6-foot-6 make him a best complement to Irving.

Allen, however, will not be playing next to DeAndre Jordan, the guy he’s alternated time with this season– which is why his play throughout this streak, in which he’s averaged 15.6 points and 12.6 rebounds while shooting 72.5%from the floor, has the Nets so fired up about what lies ahead.

“[Nets coach] Kenny [Atkinson] challenged him in film one video game to not be as up and down, but to simply be up, and to dip into that level,” forward Garrett Temple informed ESPN. “‘ We see that you can and we require you to be at that level to be effective,’ and he’s taken that challenge head on and he’s been fantastic.

” I think he comprehends what he can do, and he’s stepped into that role. ‘I can be this dominant within and my group requires me to be dominant so I’m going to be dominant like that.‘”

The Webs still have plenty to sort out. The offense will undoubtedly look various whenever Irving returns– which, after he went back to on-court work Friday, appears to be getting closer. LeVert’s return will come a couple weeks after that. As they wait for those guys to return, the Webs have to feel excellent about what they are seeing in their absence.

On the very first 2 possessions of the 2nd half of Celtics-Nets, Boston center Daniel Theis missed out on a brief runner in the lane, then saw Allen go right past him for an offensive rebound and a putback dunk.

Celtics coach Brad Stevens had actually had enough. Enes Kanter looked into the game for Theis 33 seconds into the third quarter, and Theis stayed anchored to the bench for the rest of the video game.

” He was available,” Stevens said when inquired about Theis after the game.

” We’ve discussed all of it year, we’re going to have a rotating center spot. Now that Enes is getting healthier, I believed that Enes was truly good in the first half, therefore we opted for Enes early.”

Later on, in referral to a concern about Allen, Stevens made his real sensations understood.

” I think we started 3 of the 4 halves we played in the last three days with a Jarrett Allen dunk,” Stevens said, “which is not a great way to begin with the Celtics’ [point] of view.”

Theis has actually been a significant part of why Boston has actually left to such a strong start, however his benching Friday was simply the most recent example of the game of musical chairs Stevens has actually been playing with his supporting cast all season, in an effort to find functional rotation pieces.

Up until now, it has been a mostly barren pursuit.

Of the players behind the team’s border stalwarts– Kemba Walker, Jaylen Brown, Jayson Tatum, Gordon Hayward and Marcus Smart— the one choice who has been functional is Brad Wanamaker, who has capably managed the team’s backup point guard minutes. However Grant Williams and Carsen Edwards— two of the group’s three novices drafted amongst the top 33 chooses in June– have struggled mightily. The third, Romeo Langford, made a 14- 2nd cameo Oct. 30 and hasn’t been seen in a game because. Semi Ojeleye, a third-year forward, stays an at-best inconsistent spot-up shooter on the perimeter.

The struggles by the rookies have actually stuck out. After going 0-for-2 against the Webs, Williams is now simply 12- for-49(245%) from the field– consisting of 0-for-21 from 3-point variety. There might not be an individual much better fit to handling such a slump, however, than Williams, who is equally both a bright character and a very positive one. That can do just so much.

” Sometimes, you simply miss them,” he said, describing his oh-fer streak from 3-point variety. “But eventually they’ll start falling, and I seem like they’ll fall when the group requires them, particularly. So I have actually got the utmost confidence in it to keep shooting them and let it fly.”

Edwards likewise isn’t shy. He likewise has struggled mightily. He is now 23- for-73(315%) on the season, and 14- for-43 from 3-point variety. More than half of his overall made baskets this season can be found in just 2 games, against the permeable defenses of Washington and Cleveland. Get those 2 video games and Edwards is shooting 20%(11- for-55) overall and 20.6%(7-for-34) from 3.

” It’s a tough modification,” Edwards said Friday. “I’m still trying to discover. At the end of the day, I’m just learning and trying to do the very best I can.”

The very same can be stated for all of Boston’s young gamers. And, at 13 -5, the Celtics are surpassing expectations. For a group that has goals of a deep playoff run, these final rotation areas all bear viewing.

Throughout a timeout in the 4th quarter at Madison Square Garden, the in-arena video camera revealed vocalist Mary J. Blige resting on celebrity row as her tune “Household Affair” shrieked through the arena’s speakers.

The Knicks’ season, nevertheless, hasn’t exactly been percolating.

The Knicks built up a 16- point first half lead Friday, only to watch it instantly evaporate after halftime. The far more talented Sixers, who looked totally unmotivated in the very first half, decided it was time to wake up and start playing, and went on to win 101-95

Losing a big result in the 76 ers for the second time in two weeks isn’t almost as befuddling as the haphazard method the Knicks are advancing through this season.

New york city is tied with the Atlanta Hawks for the worst record in the Eastern Conference at 4-15 It appears the team is still more focused on attempting to win than trying to see what it has in its young players. That is the only explanation for Kevin Knox, the No. 9 pick in 2015’s NBA draft, getting a DNP-CD Friday night.

” The flow of the game,” Knicks coach David Fizdale said later when asked why Knox didn’t play.

” But by no ways is Kevin buried. He’s going to need to combat his escape of it. I got a great deal of confidence that he will.”

There isn’t a ton of proof so far in his profession that Knox is going to be a good NBA gamer. He is shooting 38%from the field this season (though, to be reasonable, he’s also shooting that from 3-point variety, where it is a reputable mark). Whether there is proof or not should be irrelevant for a Knicks team that wasn’t anticipated to be competitive this season by anyone outside the organization.

The team’s goal must have been to learn what it has in Knox, Mitchell Robinson, RJ Barrett and Frank Ntilikina Absolutely nothing ought to obstruct of that– particularly after the dreadful start ought to have removed from the formula the faint concept that this group would be excellent.

However, in Fizdale’s defense, this is the position the group put him After a loss to the Cavaliers previously this month, group executives Steve Mills and Scott Perry– at the request of owner James Dolan– held an impromptu news conference and declared, “We believe the team is not performing to the level that we anticipated or we anticipated to carry out at, which’s something that we believe we jointly need to do a better task of delivering the item on the floor that we stated we would do at the start of this season.”

There is still a lot of time for the Knicks to shift their priorities to the important things that need to matter: completely focusing on the development of those young gamers. Until they do, nevertheless, an unsightly season will just continue to get uglier.

Joel Embiid acquire a game-high 27 points and 17 rebounds while Ben Simmons includes 15 points and 8 assists as the 76 ers beat the Knicks 101-95

There is one style that has actually been consistently apparent about Philadelphia’s start to its season, and it was on display screen once again Friday, even in a halfhearted victory over an overmatched Knicks team. It’s been something Sixers coach Brett Brown has stated consistently, consisting of prior to Friday’s video game: The offense has to overtake the defense.

The numbers bear that out. The Sixers now have the NBA’s third-best protective performance, and are within a half-point of having the top-ranked unit. Offensively, however, Philadelphia ranks simply 18 th in the league.

” We simply really have to find our flow,” forward Tobias Harris said. “We need to move our bodies a bit more and just execute.

” Some games we do among the 3, or two of the 3. When it’s excellent, and we’re clicking, it looks real good. We’re not going to be best, but we have some strides to make at that end.”

It was always going to be an operate in development for the Sixers at that end of the court. Unlike almost every other team in the league, the Sixers are depending on size and strength to produce points, rather than spacing and shooting. It’s a mix that is going to need time to be figured out.

But there are signs that it will work. That starting 5, in the minimal minutes it has played together, has impressed, outscoring opponents by 21.3 points per 100 possessions. The fact that the group has appeared in just 9 of Philadelphia’s 19 video games– and for a total of 102 minutes– is a familiar advancement. The Sixers had comparable concerns getting their finest players on the floor together last season.

” I seem like we entered into an excellent circulation,” stated guard Ben Simmons, who had 15 points and eight assists Friday. “There’s ups and downs, which takes place, but we’re type of discovering it.”

There have actually been flashes of what the Sixers can be– like their opening night win versus the Celtics and last Saturday’s demolition of the Miami Heat, both can be found in Philadelphia. The 13 -6 record isn’t bad, either. There’s still much work to be done if the Sixers are going to be the team they hope to end up being.
