A risk assessment of PCBs and other contaminants in farmed and wild salmon was flawed and did not reflect public health community opinions.
Even with dedicated aerators, aquaculture farms can experience stress and mortality in culture animals due to low dissolved oxygen concentrations in pond water. Simple tractor-powered aerators offer a quick and portable solution to low dissolved oxygen levels that provides strong emergency aeration and water movement.
It is technologically feasible to recover functional muscle proteins and lipids from fish processing byproducts using isoelectric solubilization/precipitation.
Emergency aeration with tractor-powered paddlewheels allowed U.S. catfish farmers to increase feeding and stocking rates, and double production.
The potential yield of catfish from earthen ponds is high, but several factors limit production under commercial conditions.
Proposed best management practices for rainbow trout production address eight areas of production covering the entire culture cycle.
Water flow within channels can be measured using the float method or calculated using rating curves that project water velocity based on a series of finite measurements.
Tilapia culture is an important component of local food production in Honduras. Rising exports have raised in-country demand and production.
Accurate estimations of water volumes in aquaculture systems contribute to both better management of resources and cost-efficient production.
In Indonesia, shrimp farming practices vary somewhat from region to region depending on the local conditions and financial pressures.
In intensive ponds and raceways, oxygen injection can manage oxygen demand and can quickly increase dissolved-oxygen levels to minimize risk of catastrophic failure.
Groundwater from wells is sometimes used to supply hatcheries and ponds. The potential water supply via wells is defined largely by geology.
A simple evaluation process can characterize commercial biofilter performance as a function of flow rate and ammonia-nitrogen concentration.
In a study, a radial-flow settler provided approximately twice the TSS removal efficiency of a comparable swirl separator.
Research has shown that microbial mats are effective at removing nitrogen and phosphorus from aquaculture effluents.
The worldwide adoption of ecologically, socially and economically sound systems based on a series of principles of organic agriculture is exemplary if unrealistic.
