Special measures for raising fish species
Nested filter and omnivorous species usually do not require special care, but they require special care for devoured species because of their small size and low ability to compete for food; poor digestion, inability to feed, or poor digestion of large fish species The rough texture of the feed is harder to feed, especially small-scale grass carp. The method of care is to use a mesh or bamboo basket to form a small food and snack table. The number of farms and stations depends on the size of the fish pond. Mesh mesh and fence gap size is determined by the larger body size of the swallowing fish body width, so that large-size fish species can not enter, only allowed to set the fish into the species. For example, if the growth of nested fingerlings is faster, large mesh nets or wider fences should be replaced in time. Feeding recipes are also taken care of. In addition to full-priced pelleted diets, nutrient-rich and easily digestible feeds can be selected according to their diet.
