While there are environmental, social and economic benefits from aquaculture facility certification, farms bear most of the costs, at least initially: procedures, equipment and services to achieve compliance. There are risks that new procedures could affect productivity and raise production costs. 

With aquaculture insurance, producers can substitute an insurance premium of a known cost for an unknown potential cost, the loss of stock. 

Those charged with determining the underlying cause of a disease outbreak have a wide variety of detective tools at their disposal. 

Each farm unit should have a written program that defines measures to prevent food safety problems and a program of regular testing. 

Combining biofloc technology with bio-secure modular shrimp culture can make operations more sustainable and economically viable. For optimized biofloc production, lined ponds and reservoirs and high stocking densities are essential. Paddlewheel aerators keep dissolved-oxygen levels high. 

The Fishery is an inland farm in California that raises largemouth bass, carp, sturgeon and catfish in a recirculating system that minimizes water use. 

In the international aquaculture trade, producers have lots of information on how their fish or shrimp were produced, but buyers may know little about a product’s safety, origins or environmental and social impacts. 

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. 

In modifying its infrastructure and related pond management, QVD Aquaculture uses floating water plants to remove nitrogen and phosphorus from the discharge water. Sludge pens capture sludge at ponds for later reuse. 

In a trial, a novel dietary vegetable oil blend was able to totally replace fish oil in tilapia diets without negatively impacting growth performance. 

Readily available energy has supported expanded seafood production. Feed production is the major energy-consuming aspect of finfish and crustacean culture. 

In China, fleshy shrimp have had much higher market value than other shrimp species. China’s aquaculture scientists and fishery agencies have therefore worked closely with shrimp farmers to rebuild the farming industry for F. chinensis. 

Algae offer advantages over terrestrial plants for biofuel production: short generation cycles and fast population growth. Algal fuel production would spare corn and soybeans for consumption as food for humans. 

In a white shrimp farm trial in a low-salinity environment, alternatives to fishmeal did not negatively impact the growth, survival or FCR of the shrimp.
