Abstract

This invention discloses an ecological polyculturing method of sea cucumber, Penaeus monodon and Portunus trituberculatus, which comprises the following steps: choosing the Portunus trituberculatus and Penaeus monodon with quick growth speed and high economic value based on the biological characteristics that the sea cucumber and decapod crustacean have different growth time and nutrition levels;and making full use of the idle water and abundant natural baits in the pond during the aestivation of the sea cucumbers to polyculture sea cucumbers, shrimps and crabs. The culturing method is characterized by optimizing the ecological environment of the pond, reducing pollution discharge and disease spread, using the water space effectively, reducing culturing and producing cost, increasing culturing output, etc.

Description

Technical field:

[0001] The invention relates to a comprehensive ecological cultivation method for sea cucumber cultivation ponds, in particular to sea cucumbers and prawns monodon that can optimize the ecological environment of ponds, reduce pollution discharge and disease transmission, effectively use water body space, reduce cultivation production costs and increase cultivation output Ecological polyculture method with Portunus trituberculatus. Background technique:

[0002] At present, in the northern coastal areas of my country where conditions permit, ponds are being built or renovated for the cultivation of sea cucumbers with high value. There are the following problems in the cultivation of single species of sea cucumber:

[0003] 1. Sea cucumbers need to use drugs to remove fish, shrimp, and crabs in the pond before releasing the seedlings, which not only increases the cost, but also causes potential damage to the pond ecosystem;

[0004] 2. Most of the ponds trea...
