Catfish feed formulation

Note that reasonable stocking reasonable stocking densities, can improve feed efficiency; suitable mix of varieties, can make full use of feed, mutualism, achieve harmony water and improve feed efficiency. For catfish farming high survival rate, feed to reduce waste, we must control the fish stocking density and with class. When the fish run, you should select 30 g / tail around the large-sized fish were into fish feed. Stocking fingerlings can be flexible according to pond conditions, management, feed supply and fingerling size, etc., appropriate stocking density sought, too thin fishing pool utilization is not high, low efficiency, is too dense fish grow slowly, to induce disease ; with reasonable pay attention to take advantage of fishing and water layer space and do not fought as a precondition. Usually acre can put 30 g / tail catfish species around 1500, and with 50 g / tail about 200 flower silver carp. The fish should be put requirements specification and tidy, bright color, smooth surface, disease no injury, no fins incomplete, infirmity, before entering the pool required 5% salt water immersion 10 minutes. Catfish species usually in late April of each year running, after gray with a silver carp to catfish into the pond and a half months before delivery, in order to facilitate the growth of catfish. In addition, as the fish continue to grow, to regulate the breeding density, improving efficiency, in batches from harvesting market and harvesting and stocking, to regulate the amount of water containing the fish, improve the feed rate of return.
