At the IntraFish Seafood Investor Forum in New York, “all roads lead to salmon.” Buoyed by high prices and soaring demand, the sector is an example worth following. But it’s not without its challenges. 

Land-based aquaculture, perhaps the ultimate environmental risk-mitigation tool, was the talk of the town at the IntraFish Seafood Investor Forum. Once scoffed at for high capital and energy requirements, RAS now has a crowded bandwagon. 

Ingredients that are properly proportioned and mixed for an adequate mixing time are very important to assure the manufacturing of aquafeeds that meet the standards for the shrimp species and life stage for which the formula was designed. 

Each year the attendees of the Global Aquaculture Alliance’s GOAL conference – held in September in Guangzhou, China – have the opportunity to answer poll questions posed by speakers and moderators of panel discussions. 

Two U.S. universities are teaming up to study the application of a novel antibody to tilapia to reduce the aquaculture industry’s use of antibiotics. The chairman of the Seafood Industry Research Fund says there could be a disruptive financial impact on seafood if it can’t compete in the “antibiotic-free” space. 

Various additives, many of plant origin, have been explored to replace the use of antibiotics in aquafeed. The authors compared the performance of rainbow trout fed diets containing oxytetracycline or mineral additives yellow loess and Song-Gang stone powder. 

At the recent GOAL conference, the British Columbia Salmon Farmers Association committed to reveal sea lice counts at farms operating in the province while promising a future without antibiotics, despite struggles with the persistent yellow mouth disease. 

A study was performed to determine the effects of puerarin, a biologically active ingredient in the roots of kudzu, on stress modulation in farmed salmon. 

A study evaluated the effects of two organic acid blends on performance, gut health and disease resistance in olive flounder. The dietary organic acids were effective in lowering total gut bacterial counts, gut Vibrio counts and in conferring resistance against Edwardsiella tarda. 

The 2001 detection of chloramphenicol in shrimp imported into the Netherlands heightened awareness of and anxiety over the presence of chemicals in food. 

Only eight active pharmaceutical ingredients available in 18 drug products have been approved by the U.S. Food and Drug Administration for use in aquaculture. The approval process can be lengthy and expensive. 

As the demand for aquaculture products increases, so does the search for environmentally friendly alternatives to antibiotics. Alternatives to antibiotics include dietary prebiotics, probiotics and synbiotics. 

There is a widely promoted misconception that eating wild-caught fish is better for the oceans than eating farmed seafood. On a global basis, however, sustainably farmed fish may represent 60 times more efficient use of anchovies and other baitfish resources than wild fish. 

The use of phages is an alternative to antibiotics in the control of pathogenic bacteria. Phage therapy offers low-cost, low-toxicity treatment and quick bactericidal effects. 

Dietary organic acids can exert antimicrobial effects and benefit growth, nutrient utilization and other health parameters in tilapia.
