The idea that fish farms’ health and safety are interconnected is not new. Even the best-run farms are not protected from diseases or pollution from another farm close by, so further measures are necessary, argues Anton Immink of Sustainable Fisheries Partnership. 

The waters off the United States’ eighth-largest city may seem an unlikely place to grow oysters, but in a surprise announcement last month, officials from the Port of San Diego said they’re aiming to do just that. 

An over-reliance on medical and chemical controls, along with warming waters, led to a surge in sea lice. With such treatments waning in effectiveness, operators turn to other, safer measures. 

Click-bait headlines playing loose with the truth can do tremendous damage in this age of 24-hour news cycles and short attention spans. Our editor tells a sad fish tale that didn’t pass the sniff test. 

Soybeans are a popular alternative feed ingredient used to replace fishmeal and fish oil in aquafeeds. Most soybeans used in these feeds have been genetically modified to reduce pesticide use and increase yields. 

Copper is used for control of the blue-green algae responsible for off-flavors in aquaculture animals, treating diseases and parasites, and avoiding cage net fouling. Although copper is an essential nutrient for plants and animals, an excess can negatively affect the environment and human health. 

Formed in 2015, following Cargill’s acquisition of salmon feed specialist EWOS to complement its own warm-water aquaculture feed business, Cargill Aqua Nutrition produces feed for salmon, tilapia and shrimp in 20 countries around the world. 

As wide use of antibiotics has led to antibiotic resistance in fish pathogens, vaccines present an alternative control method to prevent bacterial diseases. 

To help increase seafood consumption and gain recognition for the many health benefits of seafood, the author identified three wishes for 2014. Change the risk profile of seafood to defuse the sensationalized status of mercury. Professionalize the capability of the retail industry and create an avenue for consistent, positive messages sent to consumers.

An in-pond raceway system for intensive pond aquaculture was successfully demonstrated in China by the international marketing program of the U.S. Soybean Export Council. 

The methods used to kill fish depend on many factors, including fish size and species, aquaculture production system, fish quantity, market preferences and effects on product quality. Also, some methods may not be approved in some countries, as with the use of anesthetics and regulations concerning the ethical treatment of animals. 

Many consumers look for an eco-label or rely on a trusted retailer or restaurant to identify sustainable seafood. Certification programs convey this assurance by providing consistent information about the origins, food safety and environmental credentials of seafood. 

Antibody-based enzyme-linked immunosorbent assay (ELISA) tests are proven, sensitive, high-throughput alternatives to more costly and complex test methods for the detection of herbicide residues and other chemicals. 

Results of this study demonstrated that a commercial, granular, SCP-based algaecide corresponding to 2.5 mg/L H2O2 can be recommended as an eco-friendly strategy to effectively remove populations of the cyanobacterium Planktothrix sp. without compromising water quality or other plankton communities.  

Bangladesh shrimp farmers are adopting measures to improve quality to comply with international standards. A survey found that most farmers visually evaluated shrimp by checking size, weight and signs of disease before harvesting. 

For small-scale aquaculture farmers in far-flung regions, creating traceability data can present major challenges, both linguistic and technological. It’s those challenges that VerifiK8 is poised and ready to help solve. 

It is time to recognize the crucial role of small-scale farmers in Asian aquaculture production and trade. The socially and economically important small-scale sector – the “mainstay” of Asian aquaculture – is innovative, but faced with constraints in modern markets. The sector needs investment from public and private sectors to compete and thrive. Another challenge is to develop certification programs in ways that promote responsible aquaculture expansion with due consideration to small-scale farming.
