While talk of preservation and conservation dominated the annual event, a blunt query reminded all that the oceans need protection and sustainable development. 

Ionic imbalance in low-salinity culture water may negatively influence shrimp survival and growth, and it is common to apply various mineral salts to low-salinity shrimp ponds. 

With Norwegian knowledge and a partnership with Mitsubishi, Urchinomics aims to turn worthless empty urchins into valuable seafood while restoring kelp forests and creating jobs. 

Water mixing and movement distributes dissolved oxygen, fertilizers, liming and other products, as well as destratifies the water column in aquaculture systems. 

Aquaculture certification programs reduce the environmental impacts of aquaculture and avoid negative impacts on biodiversity, but no single indicator of biodiversity can be used as a standard in aquaculture certification. 

A dose-response study was conducted in an outdoor biofloc system to begin quantifying the stocking rate production function for sunshine bass advanced fingerlings. 

Bill Mook’s oyster farm is adapting to more frequent and intense rains, more acidic and warming seawater and other challenges that climate change brings. 

Intensification of pond aquaculture involves the use of commercial fertilizers such as urea and triple superphosphate to stimulate phytoplankton blooms. There is no objective way of determining the ideal fertilization rate for an individual pond. 

Commercial nitrogen and phosphorus fertilizers are widely used in aquaculture production systems to stimulate phytoplankton growth and the food web that provides natural food organisms beneficial to stocked fish fry and shrimp postlarvae. 

Several large shrimp farms in Latin America, originally built to operate using significant, flow-through water exchange with the surrounding environment, have been retrofitted to a recirculating operation mode. This modification provides numerous benefits, including improved biosecurity. 

Confusion can result because of differences in units (dimensions) used to report water quality variables, which can lead to faulty assessments. Professor Claude Boyd discusses issues related to units of measure for some common water quality values in aquaculture. 

Algunos pescadores de langosta de Maine están recurriendo a la acuicultura en un intento por diversificar y dar a las libras de langosta una segunda oportunidad de producir mariscos locales. 

Farming sea cucumbers – known as sea slugs in China – is changing people’s lives, giving rural workers in Madagascar a potential pathway out of poverty. 

As aquaculture grows as an economic engine, consumers, seafood buyers, NGOs and governments are pushing to assess and rate farms’ environmental performance. Establishing clear measurements remains a challenge. 

The new Global Estimates of Modern Slavery report released by the International Labour Organization indicates that 24.9 million workers at any given time in 2016 were in modern slavery. One in 10 of those workers around the world was working in the fishing and agriculture industries.
