From yeast, researchers learn how populations collapse
Findings could help fishery and wildlife managers monitor their stocks before disaster strikes. Written by Anne Trafton, MIT News Office.You can read the original new in MIT NewsIn the early 1990s, overfishing led to the collapse of one of the most bountiful cod fisheries in the world, off the coast of Newfoundland. Twenty years later, the cod population still has not recovered, dramatically ...

Overfishing in the Gulf of Thailand: policy challenges and bioeconomic analysis
This paper estimates maximum sustainable yield and maximum economic yield from Schaefer and Fox surplus production bioeconomic models to find evidence of biological and economic overfishing, and their consequences in Gulf of Thailand demersal fisheries. The paper examines alternative policy instruments to reduce overfishing. The discussion emphasizes strengthening fishery management for ...

Bioaccumulation of contaminants in recreational and forage fish in Newport Bay, California in 2000-2002
Untitled Document Newport Bay is an important southern California estuary that is both a developed marina in its lower bay and an ecological reserve in the upper bay. Recreational anglers catch fish for consumption, particularly in the lower bay, and threatened bird species consume small forage fish in the upper bay. Although the ecology of the fish community has been ...

Mercury in Freshwater Fish of Northeast North America – A Geographic Perspective Based on Fish Tissue Monitoring Databases
As part of an initiative to assemble and synthesize mercury (Hg) data from environmental matrices across northeastern North America, we analyzed a large dataset comprised of 15,305 records of fish tissue Hg data from 24 studies from New York State to Newfoundland. These data were summarized to provide mean Hg concentrations for 40 fish species and associated families. Detailed analyses were ...

Fathead Minnow response to broad‐range exposure of β‐sitosterol concentrations during life cycle testing
β‐sitosterol concentration in pulp and paper mill effluents is typically greater than other phytosterols, and has been shown to cause a variety of effects in fish. We exposed Fathead Minnow (Pimephales promelas) to low (22 ± 0.93 µg/L), medium‐low (70 ± 2.1µg/L), medium‐high (237 ± 5.5 µg/L), and high (745 ± 16.2 µg/L) concentrations of β‐sitosterol; and a negative (water), positive (ethynyl ...

Wreck Removal - Palymyra Atoll - Case Study
In the summer of 1991,a 121 foot long Taiwanese long line fishing vessel, the HUI FENG #1, ran aground on an atoll in the middle of the Pacific. With a footprint of just 4.6 square miles Palmyra Atoll forms the most northern vegetated island in the Northern Line Islands, lying some 1,000 miles south of Honolulu. The atoll has a long storied past and is now a national monument and wildlife ...

Artificial Intelligence in Aquaculture
The seventh and final installment in the series “Happy Fish – How Aquaculture Operators are Growing Better Fish.” While we will only be able to scratch the surface of this topic, there is great potential in machine learning and artificial intelligence applied with aquaculture and fish farm systems. We wanted to ask leading industry experts Matt Clarke of Poseidon Ocean Systems, ...

floating fish feeds vs sinking feed pellets
Generally there is no nutritional difference between floating and sinking feed. Advantages of floating feed • High Nutrition Retention • Environment-friendly • Easy to Store • Best for a Young Fish Breed • Monitoring the fish Advantages of sinking feed • Better for fish who likes to live in bottom level of water. • Great for sky or pavid fish that are scared ...

Pacific fisheries need tech to track climate impact
Climate change could benefit some Pacific fisheries, but tracking the success of adaptation needs effective monitoring, says Johann Bell. Climate change could derail plans by Pacific Island countries and territories (PICTs) to use fisheries and aquaculture to foster economic development and food security. Bottom-dwelling coastal fish are expected to be hardest hit. Under continued high ...
