USDA_logoIdentifying juvenile and adult yellow perch females from males is no longer an obstacle for aquaculture producers of this high-value fish, thanks to U.S. Department of Agriculture (USDA) scientists. A new step-by-step procedure developed by the scientists makes it easier to separate fish by gender for growth performance, physiological studies and to manage broodstocks for reproduction and genetic selection.

Physiologist Brian Shepherd and his colleagues at the Agricultural Research Service (ARS) Dairy Forage and Aquaculture Research Unit in Milwaukee, Wisconsin, developed the systematic method to segregate yellow perch females from males during early growth stages. Because females tend to grow faster and larger than males, females could often be mistaken for males when being selected for genetic improvement prior to reproductive maturity. Previously, it was extremely difficult to identify gender until fish matured (up to two years).  Read more …

The Fish Site logoFarmed salmon is rich in fat, but fillets of farmed salmon contain less marine omega-3 than previously, because a large fraction of the fish oil in the feed has been replaced by plant oil. Scientists have discovered a way of stimulating farmed salmon to convert plant oil in the feed to marine omega-3.

This means that farmed salmon may become a net producer of marine omega-3.  Read more …

Demand for salmon is soaring and is driving expansion of aquaculture—fish farming. For years, environmentalists advised conscientious consumers to avoid farmed salmon, but that’s starting to change, thanks to an evolving industry.

Rich in protein and heart-healthy omega-3 fatty acids and low in saturated fats, salmon is increasingly being marketed as a healthy food. Demand for salmon has risen more than 20 percent in the last decade. Consumption is three times what it was in 1980.  Read more …

WASHINGTON – The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is lifting the Viral Hemorrhagic Septicemia (VHS) Federal Order that was first issued in 2006 in response to an outbreak of the fish disease in the Great Lakes region. 

After studying the disease, conducting surveillance and evaluating the latest science, APHIS has determined it can safely remove the Federal Order as long as states maintain existing VHS regulations and other practices to reduce risk.

By removing the Federal Order, which has become duplicative with state regulations, we can still protect the health of farmed and wild fish while also supporting the interstate movement needs of the aquaculture industry. Beginning June 2, APHIS will no longer prohibit or restrict the interstate movement of VHS-susceptible species of live fish from VHS-affected or at-risk states, including: Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania and Wisconsin. In addition, APHIS will no longer restrict the importation of the same species of live fish from Ontario and Quebec, Canada into the United States. However, this action does not affect the U.S. Fish and Wildlife Service’s salmonid importation requirements as found in title 50 of the Code of Federal Regulations.

Although APHIS will no longer regulate VHS, the Agency’s Veterinary Services program will continue to work with states and industry to promote sound biosecurity practices and share scientific updates regarding the disease.

USDA NIFA logoPlease find attached (PDF) a Federal Register notice announcing a series of public meetings to obtain comments on a proposed rulethat would establish requirements for shippers, carriers by motor vehicle and rail vehicle, and receivers engaged in the transportation of food, including food for animals, to use sanitary transportation practices to help ensure the safety of the food or feed products they transport. This may have implications for the commercial aquaculture feed manufacturing and transportation industries.

The Food and Drug Administration (FDA or we) is announcing three public meetings to discuss the proposed rule that would establish requirements for shippers, carriers by motor vehicle and rail vehicle, and receivers engaged in the transportation of food, including food for animals, to use sanitary transportation practices to help ensure the safety of the food they transport. The proposed rule is part of our larger effort to focus on prevention of food safety problems throughout the food chain and is part of our implementation of the Sanitary Food Transportation Act of 2005 (2005 SFTA) and the FDA Food Safety Modernization Act (FSMA). The purpose of the public meetings is to inform the public of the provisions of the proposed rule and the rulemaking process (including how to submit comments, data, and other information to the rulemaking docket) as well as solicit oral stakeholder and public comments on the proposed rule and to respond to questions about the rule. usa online casino echeck

World Fishing & Aquaculture interviews Norwegian modern fish farming pioneer, Bjørn Myrseth to discover what he believes the future holds for the fast growing industry.

Fish that do not require fish protein in their feed will become important in tomorrow’s aquaculture, says Norwegian fish farming pioneer, Bjørn Myrseth. “I will continue to work with marine fish that can be grown in cages, but at the moment I am also interested in taking a look at the herbivore or omnivore fish that are sold at low prices such as tilapia and pangasius.”

This is far removed from the farming of rainbow trout and Atlantic salmon in Norway, which is where Mr Myrseth began his long career in aquaculture. This career has taken him all over the world and has involved the farming of many species.  Read more …

 

FIS_logoA young Chilean researcher was awarded a prize by a prestigious US institution for her research aimed at developing technology to obtain antibiotics substitute for farmed salmon.

Recirculating aquaculture systems (RAS) are increasingly used to rear aquatic animals – as this use increases so does the potential for loss from disease. Unfortunately, few drugs are presently approved in the U.S. for use in RAS to control disease. This survey<http://www.surveymonkey.com/s/Viterbo_RAS> seeks to develop information that will make it easier for safe and effective drugs to be approved for use in RAS.

As part of the drug approval process, the U.S. Food and Drug Administration assesses not only the efficacy of the drug for its intended purpose, but also its potential direct and indirect effects on the treated animals and the environment. There is little information currently available that summarizes how the various types of RAS are actually operated and the conditions under which a drug might be applied in those RAS. There is even less information available on how drugs might affect RAS biofilter operation and function; this information is important for determining the fate of drugs within RAS facilities, their potential effects on water quality, and for evaluating how much of the drugs might be released in RAS effluents. The lack of this broad baseline information on RAS and biofilters complicates the FDA’s assessments of potential risks to both the treated animal and the environment.

Viterbo University (La Crosse, Wisconsin) developed this survey<http://www.surveymonkey.com/s/Viterbo_RAS> to describe current RAS operations and procedures, which, when combined with other drug effects information, will help inform the decisions FDA makes in regards to the approval of drugs to control disease in animals reared in RAS.

National Aquaculture Association logoThe National Aquaculture Association (NAA) is presenting a free webinar, “Fish Nutrition 101:  What Fish Farmers Need to Know about Feeds and Feeding”, on November 19, 2013.

Feed represents the largest cost of production in aquaculture, and there are very few aspects of aquaculture that aren’t directly or indirectly influenced by feeds and feeding practices.  Growth and efficiency, broodstock performance and gamete quality, product value, water quality and effluent management, budgets and business planning, environmental impacts, etc.—what you feed and how you feed it affects virtually everything from egg to plate.

In this webinar, we will discuss the basic nutritional requirements of fish and how these differ from terrestrial livestock, attributes of feeds and how to choose the best one for your operation, and feeding strategies to maximize efficiency.  Special topics, including fish meal/fish oil sparing and omega-3 enriched products will also be discussed.

Please join us at this free National Aquaculture Association webinar to learn more about the practical aspects of fish nutrition, aquafeeds, and feeding practices.

Please see the information below on a new decision support tool for screening non-native freshwater fishes is now available on the Centre for Environment, Fisheries & Aquaculture (CEFAS) website.  Thanks to Jeff Hill with the Tropical Aquaculture Laboratory at the University of Florida for providing this information.

This is the Fish Invasiveness Screening Kit (FISK) v2.03 developed in a collaboration between UF Fisheries and Aquatic Sciences (Hill and Larry Lawson), CEFAS (Gordon Copp), and the Florida Fish and Wildlife Conservation Commission (Scott Hardin) with assistance of Lorenzo Vilizzi (La Trobe University/Murray-Darling Freshwater Research Center).

This risk screening tool has been used in several international projects and published journal articles and is now freely available online (Excel spreadsheet tool and user guide pdf).

The revisions resulting in FISK v2.03 (Lawson et al. 2013) and an application of the method to non-native freshwater fishes in FL are parts of Larry Lawson’s MS thesis (UF FAS grad student and Tropical Aquaculture Laboratory Farm Manager/Biologist).

Special thanks to Larry, Gordon, Scott, and Lorenzo for all their hard work on this project.

Please contact me if you would like additional information on FISK, the development of FISK v2.03, or its applications.
