Efficient sand lance feeding method

Abstract

The invention relates to the technical field of fish breeding, in particular to an efficient sand lance feeding method. The method comprises the steps that sand lance is bred by reasonably arranging a culture area, putting a large amount of phytoplankton in the culture area, laying a certain thickness of fine sand at the bottom of the culture area, feeding zooplankton and mineral substances which are reasonable in proportion, accurately controlling water temperature and the like, and the sand lance can inhabit a sandy sea area like in a natural environment; meanwhile, the sand lance is caught in a fine mesh bag to prevent the sand lance from running into a concrete wall of the culture area, the sand lance takes common phytoplankton and zooplankton and takes an antioxidant of bamboo leaves and tea dust as assistance, on one hand, the survival rate of the sand lance is increased, and on the other hand, growth and weight increasing of the sand lance are accelerated. According to the technical scheme, design is scientific and reasonable, the method is simple and efficient, the problem that in the closed fishing seasons, fishermen go to the sea to illegally catch the sand lance, so that the ecological chain of the marine environment is destroyed is greatly solved, and therefore the prospect of large-scale application and popularization is achieved.

Description

technical field [0001] The invention relates to the technical field of fish breeding, in particular to a method for efficiently raising the crocodile carp. technical background [0002] Jade tendon fish, also known as silver needle fish, is commonly known as noodle fish. Fish class, Yujin fish family. The body is slender, slightly flattened, and the adult fish is about 10 cm long, blue-gray or milky white, translucent, with a large mouth and canine teeth; the dorsal fin is long, and there is no pelvic fin. Inhabits the sandy bottom near the sea, often lurking in the sand. Distributed along the Bohai Sea and the Yellow Sea. It is one of the important economic fish in the north. It is rich in nutritional value and is an important bait for most fish, which plays an important role in the sustainable development of marine fisheries.

Problems solved by technology

In recent years, due to the increase in fishing intensity and environmental changes, its resources are decreasing day by day, and it is urgent to use and protect them rationally. Therefore, the state has established a regulation that no fishing is allowed during the fishing moratorium. It is not high and the market demand is huge, so many fishermen still secretly go to sea to fish illegally, but once the fishing is overdone, the number of mackerel will be greatly reduced, and fish species such as Spanish mackerel, which are at the upper level of the marine food chain, will not be found. Therefore, it is particularly important to study a breeding method to improve the survival rate of the tentacle fish.
