Tilapia culture in Ecuador
Tilapia culture in Ecuador is marked by vertically integrated companies that manufacture their own feeds and practice polyculture with Pacific white shrimp.

Pangasius juveniles tolerate moderate salinity in test
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.

Hydrolyzed fish: Alternative ingredient for aquafeeds
Hydrolyzed fish byproducts can serve as highly digestible feed ingredients with significant amounts of amino acids and fatty acids.

Minimizing antimicrobial resistance in aquaculture
Important points for aquafarmers to consider to minimize antimicrobial resistance and maximize efficacy when using antibiotics.

Growth trials study feeding frequency in shrimp
Feeding frequency is a key part of feed management. Distributing a daily ration as multiple feedings improves growth and improves water quality.
Aquafeeds
Water stability, texture of shrimp feeds formulated with natural, synthetic binders
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.

Trials test cottonseed meal as soybean replacement in 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.

Nitrogen management for shrimp nutrition in low water-exchange production systems
Research in culture systems without water exchange indicates that dietary protein levels have great impact on dissolved inorganic nitrogen loading.

Shrimp production systems with low/no water exchange
Research in a culture system without water exchange indicated that biological performance of postlarvae was similar.

Advantages of aerated microbial reuse systems with balanced C:N, part 2
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.

Advantages of aerated microbial reuse systems with balanced C:N, part 1
An alternative waste treatment is intense microbial processing of wastes to facilitate high yields with little or no water exchange.

Advantages of aerated microbial reuse systems with balanced C:N, part 3
Aerated microbial reuse systems recycle nutrients in the form of organic detritus, which consists of aggregates of organic particles coated with a film of bacteria.

Initial evaluation of shrimp vitamin requirements in laboratory tanks without water exchange
Only a few studies have been conducted with a few species. Shrimp vitamin requirements are simply trace amounts for maintenance metabolism and growth.

Recirculating and static shrimp culture systems
The static shrimp culture system did not negatively affect survival and had a positive effect on growth compared to the recirculating culture system.
