Problems solved by technology

Golden squid likes to eat live bait, and the pool water must be clear, which greatly limits the promotion of this species. The society urgently needs a high-yield, efficient, and environmentally friendly golden squid breeding model to solve the bait and water quality problems in the golden squid breeding process

Abstract

The invention relates to an ecological polyculture method for mainly raising golden squid in a pond. The steps include: clearing the pond, digging a deep ditch in the middle of the pond, increasing a gentle slope on the inner side around the pond, covering the gentle slope with a layer of geotextile, and laying PVC reinforcement on the bottom of the pond. Oxygen pipeline; when the pond water temperature reaches 7-8°C in spring, stock clam seedlings in the pond; when the pond water temperature rises to 12-13°C, stock white shrimp with eggs; when the pond water temperature rises to 14-16°C After that, the golden squid larvae are stocked; then the bait combination is fed. The present invention utilizes the ecological complementarity of golden squid, white prawns and clams to carry out polyculture, clams purify water quality, golden squid can feed on white prawns, and there are groups of white prawns in different stages in the pond, which satisfies the requirements of golden squid for live bait demand; and the golden squid eats mostly sick and weak white shrimp individuals, which effectively controls the spread of shrimp diseases, thereby achieving the goals of high yield, high efficiency and environmental protection.

Description

technical field [0001] The invention relates to a method for polyculture of golden squid, in particular to an ecological polyculture method for mainly raising golden squid in ponds. Background technique [0002] Golden squid ( Sepia esculenta ), also known as cuttlefish and mullet, are distributed in the Bohai Sea, the Yellow Sea, the East China Sea, the South China Sea, the Japanese Islands and the Philippine Islands. The golden squid is one of the most important economic species in the world squid family. Its annual output ranks second among the squid species in the world. Yellow croaker, small yellow croaker and hairtail are collectively known as one of the four traditional fisheries in my country and are important fishing targets. However, since the 1980s, due to various reasons such as overfishing and the destruction of the marine environment, its resources have declined significantly, and its output has declined sharply. At present, the golden squid has disappeared in...
