The Fish Site logoIn a new study, Hansa Done, PhD candidate, and Rolf Halden, PhD, researchers at Arizona State University’s Biodesign Institute, examine antibiotic content in the rapidly expanding world of global aquaculture.

Ms Done and Mr Halden measured the presence of antibiotics in shrimp, salmon, catfish, trout, tilapia and swai, originating from 11 countries. Data showed traces of five of the 47 antibiotics evaluated.

The research findings and a discussion of their implications appear in the current issue of the Journal of Hazardous Materials. Read more …

As the world grows hungrier for animal protein, insects could be the new way to feed livestock.

Most farmers go to great lengths to keep insects at bay. For a growing cadre of livestock and fish producers though, bugs have never been so welcome. us online casinos echeck

Despite the appearance of some insect-based foods on store shelves — protein bars and tortilla chips made from crickets, for instance — creepy-crawlies are still a little distasteful for most.

However, food producers are likely to feel the pinch as the world’s population climbs to nine billion by 2050, while rising incomes in large countries like China and India lead to greater demand for meat-rich diets. So entrepreneurs, researchers, and even the United Nations are looking for an animal feed less expensive than the soybeans and fishmeal typically used today. Insects like mealworms and fly larvae, a natural food for wild birds and fish, could be a near-perfect replacement. With several startups planning industrial-scale operations, it may not be long before some poultry or fish entrées are raised on a regular diet of bugs.  Read more …

The North Central Regional Center for Rural Development (NCRCRD) at Michigan State University is continuing our webinar series “Innovations in Agriculture and Rural Development.” Webinars feature technology that has been developed by the 12 North Central land-grants and all our webinars are free to anyone interested. The primary goal is to help disseminate information regarding new innovations in agriculture. The secondary goal is to help generate potential intermediate/end user feedback for technology developers.

NCRCRD´s next webinar is about efforts directed at improving animal health, nutrition, and production efficiency in aquaculture.

More Webinar Details:

Title: Prairie AquaTech:  Improving animal health, nutrition, and production efficiency.
Date: Tuesday October 21, 2014
Time: 12:30 PM ET/11:30 AM CT

Description: Roughly two-thirds of the world’s major fish stocks are currently fished at or above capacity. To keep pace with global demand, about half of all seafood consumed is now farmed. Without aquaculture, the UN FAO reports the world will face a significant seafood shortage by 2030. This has led to a significant demand for sustainable aquaculture feedstuffs and health supplements, which is the largest operating cost for aquaculture production. Prairie AquaTech specializes in new microbial approaches to aquaculture and other animal feeds and health supplements, and has developed a process that will replace more expensive natural resources currently being used in animal feeds, such as fishmeal. Their current research focus is optimizing feed and health supplement formulations and conducting feeding trials to produce high protein feed ingredient replacers that are lower cost, blend-ready to meet species-specific nutrient requirements, and provide immune system enhancement.  Prairie AquaTech is currently producing 1 ton of product per day at its pilot scale facility and is conducting animal feeding trials throughout the world.  The next step is to break ground on a 15,000-ton commercial plant, which will provide product to feed manufacturers in the animal health industry.

About the presenters:

Dr. Bill Gibbons is a Professor of Biology and Microbiology at South Dakota State University and Chief Scientific Officer, Processing, at Prairie AquaTech.

Dr. Mike Brown is a Distinguished Professor of Fisheries Science at South Dakota State University and Chief Scientific Officer, Nutrition, at Prairie AquaTech.

Mark Luecke is the Chief Executive Officer at Prairie AquaTech.

There has been recent interest by the aquaculture/baitfish industry and regulators to develop some type of certification/verification program to ensure that AIS-HACCP/Aquaculture Biosecurity procedures are actually in place and working. Such a certification/verification program does not exist in the North Central Region, thus pilot programs for Michigan and Minnesota will be explored and will be discussed at the workshop.

To continue these efforts Michigan Sea GrantMichigan State University Extension, and the North Central Regional Aquaculture Center (NCRAC) will be offering an Aquatic Invasive Species-Hazard Analysis Critical Control Point (AIS-HACCP)/Aquaculture Biosecurity Workshop that will be held on October 21, 2014 in Clare, Michigan at the Doherty Hotel. The workshop will run from 9:00 am to 4:30 p.m. There is no registration fee for this workshop.

For more information, please contact Ron Kinnunen at or (906) 226-3687.

USDA NIFA logoScientists from the USDA/Agricultural Research Service and the USDOI/Fish and Wildlife Service, have revised and added additional ingredients to Nutrient Digestibility Database.  The project started in 2005 and is designed to evaluate traditional, new or modified feed ingredients for the availability of nutrients to rainbow trout and hybrid striped bass.  All the experiments include diets manufactured under commercial conditions (cooking extrusion) and standardized methods so comparisons over time and among ingredients can be made. A more detailed explanation of the projects purpose, methods and results can be found in an excel spreadsheet that can be downloaded from:

The information includes pages for: Project Description, Procedures, Reference Diet Formulations, Nutrient Composition of Ingredients, Apparent Digestibility Coefficients (ADC’s) Trout, ADC’s Hybrid Striped Bass, Total and Digestible Nutrients Trout, Total and Digestible Nutrients Hybrid Striped Bass, ADC’s grouped by type of Ingredient for Trout, Anti-nutrients for some ingredients, Acknowledgements, and Contacts for further information.

FIS_logoThe Aquaculture Sanitary Committee of Sonora (COSAES) recommends aquaculture producers to request the appropriate health certificate for transferring tilapia living organisms and the fishing guide.

This recommendation is aimed at preventing the onset of new diseases in the country, caused by the bacteria Francisella and Streptococcus, or the parasite Gnathostoma, among other pathogens, which would have serious health and economic consequences for the aquaculture producers of Sonora.  Read more …
