The sustainability of farmed seafood is directly tied to how efficiently the animals turn their feed into flesh, aka food for people. Farms that use more feed to grow the same amount of food are more impactful than others. But what also matters is the kind of feed given to cultured species. Typically, fish and shrimp are fed fishmeal, a kind of feed made from ground-up fish. Fishmeal can be made from the excess trimmings of fish processing, but there are several wild-caught fisheries that only serve to be reduced into fishmeal for aquaculture, e.g. Peruvian anchoveta. However, with a growing market for farmed seafood, fishmeal is in high demand.
This has raised fishmeal prices worldwide; so some shrimp farms, most of which are in developing countries, have begun to substitute fishmeal with plant-based feeds. A recent paper in Sustainability, Malcorps et al. 2019, set out to measure the environmental and social impact of substituting fishmeal for plant-based feed in farmed shrimp. Currently, shrimp feeds are 20-30% fishmeal, depending on the shrimp species being farmed—what would the environmental impact be if those percentages dropped?
AYLMER, ONT. — In the middle of giving a tour, Sheldon Garfinkle peers into one of his company’s water tanks. Blue shrimp the size of fingers dart away from him, hiding in the far corners.
“They can hear us,” he said. “They are very sensitive creatures.”
Garfinkle’s great accomplishment is that these sensitive shrimp are alive at all, trotting around tanks stacked six levels high. For five years, the biggest problem in Canada’s fledgling, indoor shrimping business has been dead shrimp. If the water is too cold, they die. If the filtration isn’t right, they die.
For the few shrimp farmers operating in Canada, a 50-per-cent survival rate is an achievement. As a result, homegrown shrimp has been a rare delicacy, served infrequently by chefs and high-end fishmongers.
On Apr 19 five suspected pirates captured a Yemeni dhow FV AL AZHAM off the coast of Somalia. Two days later on 21 April, the pirates attacked the Korean fishing vessel ADRIA with the dhow acting as a mothership in the Indian Ocean some 280 nautical miles off the coast of Somalia. FV ADRIA started to conduct evasive manoeuvres and increased its speed. The Spanish Fishing Vessel TXORI ARGI was operating in the vicinity and proceeded to assist the FV ADRIA as she continued to be chased by the skiffs. After approximately one hour, both vessels were approached by the skiffs and fired upon with what was believed to be a rocket propelled grenade. The Private Armed Security Teams (PAST) on board of both tuna fishing vessels responded, and the skiffs retreated. That same day, another Fishing Vessel, FV SHIN SHUEN FAR 889, also reported having been approached by two skiffs, which both retreated when the PAST on board revealed their weapons.
On 21 April, EU NAVFOR dispatched its Maritime Patrol Aircrafts (MPRAs) and conducted a search in the area, resulting in identifying the mothership. On 23 April, in collaboration with its MPRAs, EU NAVFOR’s flagship ESPS NAVARRA successfully intercepted and boarded the captured dhow vessel. EU NAVFOR apprehended five suspected pirates, and the 23 hostages aboard the hijacked FV Al Azham were released unharmed.On Apr 19 five suspected pirates captured a Yemeni dhow FV AL AZHAM off the coast of Somalia.

What to do with the four Lower Snake River dams and how to best protect imperiled salmon have been a tough questions for decades. They were the focus at a conference on salmon Tuesday at Boise State University’s Andrus Center for Public Policy.
Bonneville Power Administration’s top official said removing the dams would be a difficult task.
Elliot Mainzer, the head of BPA, said he’s doing “significant due diligence” to understand the best path forward to protect salmon, while still keeping energy costs low. He said the administration must adapt and change.
“We’ve got to try to lean in a bit more for the fish,” Mainzer said.
PUTRAJAYA - A multi-agency task force will be set up soon to check the increasing incidence of encroachment by foreign fishermen, Home Minister Tan Sri Muhyiddin Yassin said today.
The task force will be led by the Home Ministry, with members from the Defence Ministry, Foreign Ministry, Malaysian Maritime Enforcement Agency (MMEA), Royal Malaysian Navy (RMN), Royal Malaysia Police (PDRM), Immigration Department, Fisheries Department, Malaysian Fisheries Development Authority (LKIM) and Malaysian Anti-Corruption Commission (MACC), he said.
"They will conduct special operations soon, and it is hoped that this action will put an end to encroachment by foreign fishermen,” he told a media conference at his ministry here.
Driving along the shores of Lake Victoria near Entebbe in Uganda, local leader Matia Lwanga Bwanika asked his driver to stop. Getting out of the car, he walked slowly into the swamplands by the lake and shook his head disapprovingly at the sight in front of him.
Fish farmers had dug up a big area of the once marshy papyrus wetland, turning it into a series of tightly packed rectangular ponds.
“This is wrong,” said Bwanika, who is the district chairperson for Wakiso and has made a name for himself as a protector of forests and wetlands. “They are literally destroying the entire wetland.”
The wetlands surround Lake Victoria, which at 68,800 square kilometres is Africa’s largest body of freshwater and drains into the Nile River. They are a natural filter for waste and chemicals, giving them an essential role in maintaining the lake as a functioning ecosystem.
Last month in Melbourne, the second Slow Fish Australia festival brought together fishers, marine scientists, seafood industry representatives, chefs, and consumers together to talk about the state of our oceans and fisheries.
Organised by Slow Food Melbourne, Slow Fish Australia sprung up largely in response to one particular event and its subsequent impact: the Victorian state government’s 2014 decision to close down commercial net fishing. This has made it almost impossible to buy fresh, local, sustainably caught seafood in Melbourne, a city of 4 million people that is renowned for its food scene. Instead, over 80% of the city’s seafood is now imported.
Not all net fishing is created equal, and the government ban has hit small, artisan fishers the hardest. The primary species caught around Melbourne, in Port Phillip Bay, are small, schooling fish that regenerate quickly. Fishers here use sustainable, traditional net-fishing methods like purse seining and haul seining, which include sorting the fish live, by hand, while they are still in the water. Bycatch is virtually zero, and the biennial State of Australian Fish Stocks reports routinely classify the commercial fish species caught here as totally sustainable.
Illegal fishing is a huge problem in West Africa. Seven million people live along the coast and the sea is their livelihood. This source of income is in jeopardy. Industrial fishing fleets from Europe and China and are ravaging coastal fish stocks. Liberia’s government has been working with Sea Shepherd for two years to try and stop illegal fishing.
SFP announces Target 75 progress United States
The Target 75 initiative launched by Sustainable Fisheries Partnership is halfway toward the goal of 75 percent of seafood production in key sectors classified as sustainable or improving toward sustainability by the end of 2020.
