The ability to culture pangasius in the low-salinity waters typical of coastal shrimp ponds in tidal zones would permit shrimp farmers to culture an additional species of economic importance and aid in diversifying the commercial aquaculture production of these areas.
Tilapia culture in Ecuador is marked by vertically integrated companies that manufacture their own feeds and practice polyculture with Pacific white shrimp.
Hydrolyzed fish byproducts can serve as highly digestible feed ingredients with significant amounts of amino acids and fatty acids.
Important points for aquafarmers to consider to minimize antimicrobial resistance and maximize efficacy when using antibiotics.
Feeding frequency is a key part of feed management. Distributing a daily ration as multiple feedings improves growth and improves water quality.
Synthetic and natural binders that provide increased water stability are often used without consideration of the final dry or wet pellet texture of the shrimp feed.
Cottonseed meal is a lower-cost protein alternative to soybean meal, but its use in commercial shrimp feeds may be limited because it contains gossypol.
Research in culture systems without water exchange indicates that dietary protein levels have great impact on dissolved inorganic nitrogen loading.
Aerated microbial reuse systems utilize intense aeration and mixing to produce yields of 10 to 30 metric tons per hectare per cycle with little or no water exchange.
