This study evaluated the impact of feeding a commercial diet, top dressed with a commercial probiotic, to Pacific white shrimp in a biofloc-dominated tank system. 

A series of experiments – including in vitro, in vivo and also field trials – investigated if a functional diet could reduce AHPND in Pacific white shrimp. 

Study illustrates the range of salinity options for shrimp production in commercial-scale biofloc systems and found no significant differences in any shrimp production metric. 

A study determined the zootechnical performance of Pacific white shrimp under different light regimes. Shrimp exposed to light had better zootechnical parameters than those with reduced or no exposure. 

Results of this study show that automated feeding systems are significantly more efficient than hand feeding in shrimp production ponds and that increases in feed input, application of adaptive technology and training of people to maintain the feeding system must all be considered. 

This study showed that a longer inoculation of probiotics will improve shrimp postlarvae growth and survival, and that a new technique developed for more accurately estimating postlarvae weight can significantly reduce the food that must be supplied. 

Results of a study show that alternative, sustainable, plant-based protein sources such as improved soybean meal may potentially replace fishmeal in Pacific white shrimp diets. 

Shrimp aquafeeds – live, fresh or formulated – should not be an entry point of potential pathogens to the shrimp and/or to their culture systems. 

Inland shrimp culture has numerous advantages – improved biosecurity, lower cost of land and reduced conflicts with other users of common resources like land and water – and will continue to expand into new areas. 

A study compared the bioavailability of crude protein and lipid from biofloc meals generated with an activated sludge system using two water sources: wastewater from shrimp experimental culture (BFL-W) and, artificially, using clean seawater (BFL-C). 

Accurate PCR testing of shrimp seedstock assures shrimp farmers that their seedstock is clean of major diseases. Ring tests verify that labs conducting PCR testing are obtaining correct, reliable and reproducible results when testing for specific shrimp diseases. 

Selection for disease resistance has been used in breeding farm animals and can be a viable option to deal with white spot syndrome and acute hepatopancreatic necrosis disease in commercial shrimp culture. In trials, heritability for AHPND resistance was low, while that for WSS was moderate. 

Fenneropenaeus chinensis was the most important farmed shrimp species in China until 1995. Lessons learned from its development made China a pioneer, especially in shrimp larval production. Shrimp farmers must enhance their understanding of the interactions of farming activities with their ecosystems. 

In a study, “pre-fertilization” in the nursery phase of a biofloc system for shrimp was tested. The objective was to accelerate the biofloc formation to minimize ammonia concentrations, avoiding high peaks during culture. 

Sodium butyrate has potential as an additive for marine shrimp diets, improving both the balance of intestinal bacterial flora and performance of the shrimp.
