Effective aquafeed management methods are critical for efficient production of farmed shrimp, and to minimize environmental impact. In the second part of his series, Editor Emeritus Darryl Jory looks at shrimp feed management in terms of application, distribution, frequency, calculations and adjustment practices. 

Throughout the United States, a handful of aquaculture entrepreneurs are farming shrimp in indoor facilities. Selling their product is not the problem – securing funds to grow to commercial scale is. Start-ups and established farms share their tales of trial and error and why, against the odds, they’re sticking to it. 

En esta última entrega de la extensa serie de tres partes de Hervé Lucien-Brun, el autor detalla los pasos finales en el proceso de llevar el camarón de cultivo al mercado. Aquí echamos un vistazo a los protocolos adecuados para recibir producto en la planta de procesamiento, para su pesaje, clasificación y congelación. 

Shrimp postlarvae acclimation before stocking into the various growout systems (ponds, raceways, tanks) is a critical – and often overlooked, sometimes taken for granted – step in the shrimp culture process. Various water quality parameters should be changed slowly so that the young shrimp have the time to gradually adapt to the new conditions. 

La cosecha de un cultivo de camarón es un paso crítico para cualquier empresa de cultivo de camarón. Varios meses de esfuerzos y recursos ya se han invertido para mejorar la calidad adecuadamente de esta cosecha, y esta calidad debe ser preservada. La decisión de cosechar implica la consideración de varios factores. 

The GOAL 2016 global shrimp production survey showed a strong rebound in 2014 (up 10 percent to 4.18 MMT), followed by a decline in 2015 (down 5.4 percent) and another recovery forecast for the next three years. Global production is expected to reach around 4.44 MMT in 2018, barring a new disease crisis. 

In this final installment of Hervé Lucien-Brun’s comprehensive three-part series, the author details the final steps in the process of taking farmed shrimp to the marketplace. Here we take a look at the proper protocols for receiving at the processing plant, weighing, grading and freezing. 

The decision to harvest involves consideration of various factors, including market prices, customers’ need, biomass and condition of the animals and others. Several steps are involved, most aimed at maintaining maximum quality of the animals as they are harvested, sacrificed, treated and transported to the plant and processed and packed. 

Some of the world’s top aquatic animal disease experts shared knowledge about mitigation techniques at the GOAL conference in Guangzhou, China. Topics included sea lice, streptococcus and EHP, which was referred to as the “most insidious” disease impacting shrimp production. 

Harvesting a crop of shrimp is a critical step for any shrimp farming venture. Several months of efforts and resources to properly raise a quality crop have already been invested, and this quality must be preserved. The decision to harvest involves consideration of various factors. 

University of Stirling Ph.D. student Simão Zacarias, who is from is Beira, Mozambique, will soon travel to Isla del Tigre, Honduras, to document evidence showing the benefits of breeding shrimp without eyestalk ablation. His is a journey of hopeful discovery. 

The nonprofit organization established by the leaders of the Global Aquaculture Alliance is answering the growing need for targeted aquaculture training. Its newly unveiled global online education platform will enable the further development of a sustainable global aquaculture industry. 

本文介绍了新兴对虾微孢子虫病（EHP）的组织学特征，使用了对患病对虾肝胰腺组织，排泄物，养殖水缸中水样和一些卤虫生物量的PCR化验分析的方法来检测到EHP的存在。(Editor's note: This article was originally published on the Advocate in English on April 15, 2016.) 

With practice and common sense, cast netting produces adequate data for successful management of shrimp ponds. It is important, from a practical standpoint, that sampling techniques are adapted to the site, natural resources and human resources available. 

Knowledge on population size and size distribution in their production ponds, along with health status assessments, is an important management tool for shrimp farmers around the world. Proper sampling planning and execution involve a number of activities to assure proper, actionable results.
