In-situ spawning induction device and in-situ spawning induction method for parent sea cucumber

Abstract

The invention discloses an in-situ spawning induction device for parent sea cucumber. The in-situ spawning induction device comprises a square frame, attachment plates, meshes, steel chains, a floating ball, a plastic rope, fixing piles and cross beams. wherein a plurality of parallel cross beams are arranged at intervals on the upper surface and the lower surface of the square frame; a plurality of attachment plates are fixed at intervals between the corresponding cross beams on the upper surface and the lower surface of the square frame; fixing piles extending out of the four vertical edges of the square frame are arranged at four corners of the bottom surface of the square frame; four steel chains are fixed to four corners of the top surface of the square frame and are mutually cross-linked at the tail ends; the meshes are bound on the six surfaces of the square frame through rolling belts; and the floating ball is connected with the cross-linking position of the steel chains through a plastic rope. The invention further provides a method for conducting the in-situ spawning induction of the parent sea cucumber through the in-situ spawning induction device for the parent sea cucumber. According to the in-situ spawning induction device and the in-situ spawning induction method for the parent sea cucumber, the problems that an artificial breeding process of the sea cucumber is tedious, labor intensity is high, a period is long and cost is high can be solved, and the problems that when the parent sea cucumbers naturally spawn in the natural environment, a spawning rate is low, and a sperm and egg fertilization rate is low can also be solved.

Description

technical field [0001] The invention relates to the field of marine biology, in particular to a device for in situ induced spawning of sea cucumbers and a low-cost and high-efficiency method for in situ induced spawning of sea cucumbers in natural sea areas using the device. Background technique [0002] In the past ten years, with the improvement of the consumption level of Chinese residents, the consumption of sea cucumbers, one of the "Eight Treasures of Seafood", has continued to rise. my country's sea areas originally had abundant sea cucumber resources, but due to factors such as overfishing, wild sea cucumber resources have become increasingly rare. exhausted. Sea cucumbers have important ecological functions such as cleaning the ocean substrate and biological agitation, so they play an important role in the marine ecosystem. In the South my country Sea, sea cucumbers are extremely important for the material cycle of the coral reef ecosystem, the periodic cycle of cal...
