Environmental Conditions Assessment for the Carp Cultured in Floating Cages on the Irrigation Canals

Abstract

Aquaculture in cages is considered an alternative to fishing in natural waters, by increasing fish production and using new water resources. This production method confers efficiency for fish farming and varies according to the ecological quality of the body of water used, its depth, and its potential for renewal. Integrated aquaculture in irrigation canals is a relatively new technological concept, used to maximize water efficiency by designing and placing removable fish raising facilities and establishing cages fish farming technologies, located on small bodies of water such as irrigation canals. The experiment was conducted over 30 days. The biological material for the floating cages has been represented by common carp with a body mass average of 453 g. A number of 450 carp specimens were distributed in a floating cage with a size of 5m×3m×3m made of galvanized panels. Results from the analysis of the gained weight was the 56.88 kg, with an initial fish loading weight per cage cubic meter of 5.43 kg/m3 and a finally result of 6.95 kg/m3 carp. In conclusion, the Cyprinus carpio species is of great interest for raising in floating cage located on the irrigation canal, because it supports a high level of adaptability and technological plasticity suitable for aquaculture.
