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.

Intestine color check complements feed management in white shrimp
A technique based on checking the color of the shrimp intestine can complement the use of feed tables and trays, which are less effective at high temperatures, when no leftovers are found.

Organic matter for pond fertilizer
Animal manures, grasses and other organic matter have been widely used as fertilizers in aquaculture ponds. The fertilizers decompose and release nutrients that promote the growth of phytoplankton and enhance the base of the food web.

History of shrimp farming
The Shrimp Book, published in 2010, brings together experts from around the world to fill the critical need for a central reference source on the state of shrimp production practices.

New procedure controls TSV in white shrimp
The authors have established a procedure to reduce the impacts of Taura Syndrome Virus in the culture of Pacific white shrimp. The procedure focuses on avoiding the molting process of shrimp by limiting culture conditions.
