Because shrimp farmers lack accurate in-pond inventory, startup Minnowtech is on the verge of offering a data-driven solution. It’s got something to do with jellyfish. 

Author discusses the development of commercial production of artemia biomass in Peru and Ecuador as an important feed for maturation of shrimp broodstock in hatcheries. 

Honduras-based Grupo Granjas Marinas believes that large-scale production of rotifers and copepods and sequential pond inoculations, in combination with short shrimp growth cycles can significantly increase shrimp production while reducing dependency on other sources of protein in feeds. 

The introduction of tilapia to irrigation reservoirs in Israel improved the efficiency of water usage and reduced the cost of water needed for tilapia culture. Although requiring considerable investment, many dual-use reservoirs were constructed and equipped for efficient harvesting. 

The establishment of land-based recirculating systems for cobia could expand production of the species. The authors, who demonstrated cobia are well suited for culture in tanks, conducted a study to compare the performance of cobia reared at different densities. 

Cholesterol is an essential nutrient for penaeid shrimp. Trials found that a digestibility enhancer based on natural emulsifiers was as effective as purified cholesterol in improving shrimp growth and feed conversion.
