Fish

Over the past 14 years, the aquaculture industry has seen a roughly 80-percent decline in the amount of pond space dedicated to catfish, from a peak of around 80,000 hectares in 2002 to about 25,000 hectares in 2016.
The National Oceanic and Atmospheric Administration (NOAA) reached a milestone in May with its first harvest of an all-female generation of mature sablefish. This is a landmark achievement as it makes the farming of this tasty, buttery fish on a commercial scale within the grasp of US fish farmers. The fish harvested weighed an average of 5.47 lbs each, for a total of a whopping 20,227 kgs (roughly 44,593 lbs).
Sea lice have long been a research focus at Fisheries and Oceans Canada's (DFO) St Andrews Biological Station (SABS). Recently, studies have focused on the ecology of their early life history stages, non-chemical methods to reduce their incidence, and genetic selection of sea-lice-resistant Atlantic salmon. These elements have been, or are being studied, in an attempt to combat sea lice outbreaks in near-shore ocean caged fish.
Canada is the second country in less than a year to decide that genetically modified salmon is safe to eat and poses no threat to the environment.
This program will cover information on designing new feed mills and selecting conveying, drying, grinding, conditioning and feed mixing equipment. Current practices for preparing full-fat soy meal processing; recycling fisheries by-products, raw animal products, and secondary resources; raw material, extrusion of floating, sinking, and high fat feeds; spraying and coating fats, digests and preservatives; use of encapsulated ingredients and preparation of premixes, nutritional requirements of warn water fish and shrimp, feed managements and least cost formulation are reviewed.
Changing the North American aquaculture industry's perception of what is a "perfect-sized" fish to produce would significantly improve the industry's performance says Dr Daniel Benetti, director of aquaculture at the University of Miami's Rosenstiel School of Marine and Atmospheric Science.
The permitting process allowing commercial fish farming in the Gulf of Mexico has been in place for a little over a year now but no one has applied for a permit, acknowledged the National Oceanic and Atmospheric Administration (NOAA) recently.
The National Oceanic and Atmospheric Administration (NOAA) is beginning the early stages of work towards opening up federal waters in the Pacific Ocean to aquaculture operations but some are concerned that developing regulations before an industry is established may prevent growth.
As wild fish stocks are being harvested to capacity and global demand for seafood continues to grow, some sectors are espousing that land-based salmon farms are the answer. At present, most land-based farms operate for smolt production. So how economically viable is it to raise salmon on land through harvest size? And what are the implications?
Good news to tilapia aficionados: tilapia has always been good for you.  A study showed tilapia’s Omega-6 to Omega-3 (n6:n3) ratios is relatively low compared to normal US diets. This disproves the “worse than bacon” allegation made in 2008 that was based on a study conducted by a research team that exaggerated its interpretation of how tilapia’s n6:n3 ratios were bad for the health.
Mike Meeker has been farming rainbow trout off of Manitoulin Island in Canada's Lake Huron since 1984. A self-described "pioneer" in the business, his first net pen was hammered together with logs he cut in the bush and floated on oil drums. He's come a long way since then. As the managing director and part owner of Blue Goose Foods, he oversees two pen sites that each produce a million pounds of trout a year.
The final report published by the Michigan state "Quality of Life" departments concludes an 18-month process, in which the Departments of Agriculture and Rural Development, Environmental Quality, and Natural Resources, considered two applications for net pen trout farming in Lakes Michigan and Huron.
