Contents. Fish stocking. Fish stocking is the practice of releasing fish that are artificially raised in a hatchery into a natural body of water (river, lake, or ocean), to supplement existing wild populations or to create a new population where previously none exists. Stocking may be done for the benefit of commercial, recreational or tribal ...
For trout, stocking rates of 30 to 50 kg/m 3 are normal at the end of a rearing cycle, while for marine species, such as sea bass and sea bream, the achievable load is lower, between 15 and 20 kg/m 3. The total volume required for a raceway is calculated by dividing the total amount of fish in kg by the desired stocking rate in kg per m 3. [17]

Recirculating aquaculture systems at the Virginia Tech Department of Food Science and Technology. Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control ...
The Integrated Floating Cage Aquageoponics System (IFCAS) was developed as an aquaculture-horticulture based on the concept of integrated farming system approach firstly in Bangladesh in 2013 to produce fish and vegetables in floating condition where waste materials (fish feces and unused feed) from fish culture dissolved in the pond water and settled on the bottom mud are used for vegetables ...
The condition index in fish is a way to measure the overall health of a fish by comparing its weight with the typical weight of other fish of the same kind and of the same length. The condition index is its actual weight divided by its expected weight, times 100%. A fish of normal weight has a condition index of 100 percent.
Inland saline aquaculture is the farming or culture of aquatic animals and plants using inland (i.e. non-coastal) sources of saline groundwater rather than the more common coastal aquaculture methods. As a side benefit, it can be used to reduce the amount of salt in underground water tables, leading to an improvement in the surrounding land ...
