IN BRIEF - Feeling the Heat: How Fish Are Migrating from Warming Waters
Saturday, June 17, 2017
The Cape Cod Canal is a serpentine artificial waterway that winds eight miles from Cape Cod Bay to Buzzards Bay. On warm summer evenings, anglers jostle along its banks casting for striped bass. That’s what 29-year-old Justin Sprague was doing the evening of August 6, 2013, when he caught a fish from the future.
At first, Sprague thought the enormous fish that engulfed his Storm blue herring lure was a shark. But as he battled the behemoth in the gloaming — the fish leaping repeatedly, crashing down in sheets of spray — he realized he’d hooked something far weirder. When the fisherman finally dragged his adversary onto the beach, a small crowd gathered to admire the creature’s metallic body, flared dorsal fin, and rapier-like bill. Sprague had caught a sailfish.
It doesn’t take an ichthyologist to know that sailfish don’t belong in the Cape Cod Canal. Istiophorus albicans favors the tropics and subtropics; it so rarely visits New England that Massachusetts didn’t even have a state record. But strange catches — including cobia and torpedo rays — have become more commonplace. Over the last decade, the Gulf of Maine, the basin that stretches from Cape Cod to Nova Scotia, has warmed faster than nearly every other tract of ocean on earth, as climate change joined forces with a natural oceanographic pattern called the Atlantic Multidecadal Oscillation to increase sea surface temperatures by 3.6 F from 2004 to 2013. The results have been ecological transformation, upheaval in marine fisheries management, and an alarming window onto the warm future of global oceans.
PANAJI - With an aim of bridging gaps and upgrading skills of local workers in the field of aquaculture and fishery sciences, Goa-based National Institute of Oceanography (NIO), has signed a five-year Memorandum of Understanding with the Agricultural Skill Council of India (ASCI).
Under this MoU, NIO and ASCI will collaborate in the various areas of capacity building programmes by conducting training programmes as per the National Skill Qualification Framework (NSQF); and assessment of trainees trained under the different short-term skill based training programmess of NIO.
Jointly, they will develop skill development centres for training and capacity building across various segments of fisheries sectors and conduct skill gap analysis for the entire fishery segment in the country or the state as deemed essential.
Seraikela - State government has set a target of producing 17,000 tonnes of fish to the Seraikela-Kharsawan district. The target exceeds 2016’s figures.
Sources in the fishery department said the target was increased this year keeping in mind the possibility of good production. “Around 20 per cent of the district is covered by water. Moreoever, the weather conditions and climate too, are favourable to a bumper fish production,” sources said.
Sources said the number of fish farmers has increased in the district over the last few years as more and more people are getting attracted to fishery.
People are earning well and are able to lead a better life, sources said.
Hydaburg, Alaska - A new fish plant opened this month in Hydaburg, a village in Southeast Alaska trying to revive its seafood industry.
Haida Wild Alaska Seafood is located in a former cold storage that hasn’t operated in nearly three decades but is now bustling with activity as the commercial fishing season goes into full swing. Hydaburg is Alaska’s largest community of Haida tribal members. About 400 people live in the coastal Prince of Wales Island village, surrounded by the Tongass National Forest.
“As soon as the trollers come in, we’re ready,” said plant manager Jess Dilts in an interview with Alaska Sea Grant.
FORT LAUDERDALE, Fla. - Scott Mobley, firefighter and creator of the first lobster deveining tool, is launching his first Kickstarter campaign on Saturday, July 1, 2017. Mobley has created the first ever tool to devein lobster safety, quickly, and more efficiently than any other method. He has appropriately named his company "D Vein."
As a fire fighter from Broward Sheriff's Office Fire Rescue, Mobley has learned to cherish every day and make it count, as it could be his last. On his days off, Mobley enjoys fishing and diving, especially for lobsters. Since he was young, Mobley dreaded cleaning spiny lobsters with their antennas the old fashion way. 20+ years later Mobley has created the first Lobster Deveiner designed to remove the intestinal tract without the hassle.
Mobley was inspired to create this one-of-a-kind tool from his love of fishing and catching lobster. This is the very first product ever invented to devein and properly clean lobster. In this campaign, D Vein will proudly introduce the Lobster Deveiner Tool.
CHENNAI - Nearly a decade after the deadly virus — white spot syndrome — delivered a killer blow to shrimp farming in India, making native species like the Indian white shrimp (Penaeus Iindicus) and the iconic tiger prawn (Penaeus monodon) ‘non-preferable’, scientists at the Central Institute of Brackishwater Aquaculture (CIBA) are exploring ways to fix the problem and put the native species back in the reckoning.
Genetic improvement and selective breeding programmes are also being proposed to match the commercial value of the Pacific white shrimp.
Currently, the industry is dominated by Pacific white shrimps (Penaeus vannamei), an exotic species that has been imported from the US since 2009, and now holding 90 per cent share in cultivation. Though it brings certain short-term advantages like high-yield, scientists say it is not wise to depend on a single species. The idea is to create a backup with desi shrimp varieties.
Ketchikan, Alaska - Sea Grant Marine Advisory agent Gary Freitag, of Ketchikan, is spreading the word about a technique that could enhance farmed oyster and kelp productivity.
University of Arizona researcher Ben Renquist and his coworkers have refined a technique to test fertilized fish eggs for high oxygen consumption and carbon dioxide production during metabolism, using a chemical they trademarked Alamar Blue®.
The high oxygen–consuming fish eggs were proven to grow significantly faster, showing promise for improved aquaculture production. Experiments were first done on zebrafish, and have also shown promise on tilapia, trout, oysters and shrimp cultured species.
New research has revealed that fish and shellfish farming contributes GBP 620 million to the national economy every year.
The industry now supports more than 12,000 jobs and Scottish aquaculture production has increased by a third in the ten years to 2015, from 142,000 to 188,000 tonnes, according to the Scottish Government and Highlands and Islands Enterprise (HIE) commissioned study.
Atlantic salmon production accounts for 90% of all economic impact, supporting 10,340 full-time equivalent jobs and generating GBP 540 million in gross value added (GVA). The contribution of other fish and shellfish species like trout, mussels and oysters is also considered as part of the study.
