Measurements of nitrogen isotope uptake can enable more efficient study of feed utilization in whole aquaculture pond systems. 

Shrimp farm performance can often be below realistic production standards. Use proven nutrition, feeds and feeding techniques to improve profitability. 

Deformities in farmed fish skeletons can result from excessively fast growth, high temperatures, insufficient calcium and phosphorus, and other factors. 

Integrated aquaponic operations can improve water use efficiency because plants participate in nitrogen and phosphorus removal and integration. 

In an experiment comparing two biofloc concentrations, shrimp grew larger and faster in low-solids, with no significant differences in survival, FCR or final biomass. 

Hybrid catfish offer production advantages over channel catfish. Trials show greater survival, faster growth and shorter production cycles. 

Sustainable development of China's tilapia industry depends largely on the market prices of products, disease control, climate and seed availability. 

In the international aquaculture trade, producers have lots of information on how their fish or shrimp were produced, but buyers may know little about a product’s safety, origins or environmental and social impacts. 

It is time to recognize the crucial role of small-scale farmers in Asian aquaculture production and trade. The socially and economically important small-scale sector – the “mainstay” of Asian aquaculture – is innovative, but faced with constraints in modern markets. The sector needs investment from public and private sectors to compete and thrive. Another challenge is to develop certification programs in ways that promote responsible aquaculture expansion with due consideration to small-scale farming. 

Meat recovered from seafood processing byproducts could be combined with nutraceutical ingredients to form customizable seafood items. 

Formalin use is a common fish parasite control, but the chemical’s potential work safety and ecological impacts are leading to a search for alternatives. 

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. 

The authors are exploring alternative models for shrimp breeding that address genotype-environment interactions with solutions that could advance breeding in South and Central America. 

A proposed new metric, the production productivity index, or PPI, reports daily production for shrimp postlarvae. The new metric converts production data into relative terms, allowing meaningful comparisons across farms and individual ponds regardless of production days, pond size or stocking density. 

Although there is increasing interest in blue catfish, a potential disadvantage of the fish when compared to channel catfish is their reported poorer tolerance of low dissolved-oxygen concentrations.
