The seine fish culture as a large-scale new breeding method has been welcomed by all localities and has achieved considerable economic benefits. The key technologies are summarized as follows:
Water: The water flow is slow and the maximum flow rate is below 0.3 meters/second. Water depth between 1.5 and 3 meters, water level difference within 1 meter, away from the channel and pollution sources.
Wai: double-layer, double-row, the bottom net is fixed with stone and anchor; two nets are set between the anti-escape observation cage, the high-yield zone in the intensive culture is double-sided cage, the net height is 2 times the maximum depth, the fish The nets used were 2# to 4# polyethylene nets (1.11 to 1.33 cm in size) and 7# to 8# nets in the fish nets (1.90 to 2.22 cm in size). Species: Choose the fish species with high quality, robust and suitable specifications, grass carp 200 to 250 g/tail, herring 500 to 1000 g/tail, head locust 50 to 100 g or 150 to 200 g/tail, carp 25 to 75 g/tail, carp 20g to 25g or 50g to 100g/tail, carp, carp 50g to 150g or 250g to 500g/tail.
Bait: mainly fresh water grass, snails, concentrates assist. Using the "two-headed, middle-green" method, a small number of feeding, and take the timing, positioning, quality, fixed-point feeding.
