Harvest is one of the most important parts of fish farming and is frequently overlooked. This phase is often under-equipped and poorly planned. In cages and raceways, harvest may be as simple as partial draining; then herding, confining and removing fish with a dip net.这个读上去感觉就是捕捞的最后个过程噢？ However, harvesting pond raised fish can be the most labor intensive aquacultural activity. onds are harvested by the drain-and-seine (total) or the multiple (partial) harvest method. Harvest should take place during cool weather (water temperature, 60-65o F) if possible. When water temperatures are 80o F or higher, harvest fish in the cool, early morning hours. It is helpful to have cool well water nearby.
Total pond harvest is accomplished by draining and seining. First, the pond is partially drained (20-30%) to concentrate the fish. Thereafter, the pond is repeatedly seined until most (80%) of the fish are captured. The pond is then drained further and the seining process is continued. Often, ponds contain an excavated depression or harvest basin where fish are concentrated and netted during final drainage. In small ponds, seines can be pulled by hand; large ponds are seined by dragging the net with trucks, tractors or small four-wheel drive vehicles. Seines are pulled from deep to shallow water.
