Details on the Lates calcarifer fish
Lates calcarifer, known as the Asian sea bass, is a large member of the Latidae family that is capable of tolerating the high salinity (Euryhaline). And it is scattered from the western Indian Ocean to the Pacific from the Persian Gulf to China, Taiwan, New Guinea and Australia and North Australia and breeding of this fish has recently started in Iran.. This type of fish is carnivorous and grows relatively fast. The desirable conditions for breeding this fish are temperature of 26 to 32 degrees Celsius and pH between 7.5 to 8.5 and salinity between 10 to 30 grams per liter and dissolved oxygen between 5 to 9 mg / liter. Meanwhile, one of the special features of this species is disease resistance and compressibility in breeding systems. Different systems can be used to breed this fish, but often in this field this fish is bred in both fixed and floating cages.
Feeding sea-bass fish in farmed conditions
Sea bass are mostly fed with fish protein waste and fish oil, but it also needs some plant-based food as a supplement. Nowadays, researchers are investigating to replace these two nutrients without spoiling the growth and weight of this fish. The market weight of this fish is about 300 to 500 grams, while by increasing the duration of breeding and controlling factors such as water temperature, the growth rate of fish can be increased and sold in different weights required by the market.
