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. 

Removing the eyestalk of broodstock female shrimp aided in the explosive growth of commercial-scale aquaculture. An undertaking by a Central American shrimp farmer has shown that producing shrimp without ablation can ease animal welfare worries without the feared drop in production. 

The control of temperature and light intensity in microalgae culture in outdoor tanks is difficult. Progress in algal biotechnology and the use of photo-bioreactors, metabolic engineering and other advances supported development of a novel underwater light bank reactor that allows for more effective light utilization by cultured microalgae. 

Many people, including health-conscious consumers, are concerned about the cholesterol content of foods such as meat, eggs and dairy products. In the case of shrimp, the cholesterol story is different because a number of research studies have demonstrated that the high percentage of “good fats” in shrimp reduce the impact of cholesterol, and that a majority of people can eat shrimp as part of a balanced diet. 

Six of the world’s leading shrimp producers are in need of aquaculture improvement projects and zone-management strategies that address pressing sustainability concerns, a leading seafood NGO has determined. 

Shrimp farmers can look to the chicken-farming industry for guidance on proper pond management. At the Nicovita Symposium in Ecuador, Dr. Dean Akiyama of Charoen Pokphand encouraged shrimp producers to overcome challenges at hatchery level. 

Early Mortality Syndrome has devastated farmed shrimp in Asia and Latin America. With better understanding of the pathogen and the development and improvement of novel strategies, shrimp farmers are now able to better manage the disease. 

Peter Bridson, who steered aquaculture research for Seafood Watch and its highly influential marketplace recommendations for six years, now runs his own consultancy, Seagreen Research. He discusses global food security, certification standards and gradually changing perceptions about farmed salmon. 

An R&D trial was conducted with shrimp biofloc technology at a commercial facility in Saudi Arabia. Results indicated that biofloc technology can be effectively applied, with some protocol adjustments, in the KSA’s extreme desert environmental conditions.
