The Shrimp Book: Intensive production of shrimp
With relatively low use of land and water, intensive aquaculture systems can support much higher production than extensive systems.

Shrimp postlarvae: Know your starting point
Shrimp aquaculture could improve its position through more accurate and consistent identification and counting of postlarvae.

Computer modeling helps grow fish
For farmers, computer modeling helps analyze crop production and environmental effects. For managers, it assists with carrying capacity assessments and licensing issues.

Temperature affects feeding behavior of Pacific white shrimp
The authors evaluated the feed passage through the intestines of white shrimp under laboratory conditions. Feed consumption on feed trays was tested four times daily at different temperatures at an intensive culture farm.

Live diets for larval fish, shrimp: Production, enrichment, feeding strategies
Live diets for reared marine larvae must be cost-effective and versatile while providing good nutrition and being easily captured and digested. Copepods offer superior nutritional value, but their rearing requires space and is laborious.

Effective management of WSSV in shrimp
As research on WSSV continues, commonsense steps can lessen the potential impacts of white spot syndrome virus on shrimp-farming operations.

Animal protein meals reduce feed costs but don’t improve shrimp performance
The authors conducted a study to determine how replacement of salmon meal with various animal protein meals in feed affected the growth performance of white shrimp.

Fishery byproducts evaluated as feeding stimulants in plant-based shrimp diets
New cost-effective additives, such as fishery byproducts, will likely be needed to meet the increasing demand for feeding stimulants by aquafeed producers.

Nitrogen isotope for evaluating protein uptake in biofloc systems
Measurements of nitrogen isotope uptake can enable more efficient study of feed utilization in whole aquaculture pond systems.

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

Glandless cottonseed meal replaces fishmeal in shrimp diet research
Cottonseed meal is high in protein and less expensive than fishmeal and soybean meal. Cotton plants can be engineered without gossypol in their seeds.

Study: Lower biofloc concentration may improve shrimp production
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.

Shrimp genetic improvement in Ecuador
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.

PPI: New metric for measuring productivity, predicting profitability
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.

WSSV and TSV: Diseases as drivers in the shrimp-farming industry
Key to avoiding the cyclical rise and fall of production and prices is the move toward controlled reproduction of shrimp to perform within the structure chosen, whether that is disease coping or disease avoidance.

Genetics key to understanding shrimp growth rates
Achieving higher growth rates in shrimp can reduce risks, cut costs and increase economic opportunities. The amount of additional growth that is achievable is related primarily to shrimp genetics.
