Embodiment Construction

[0029] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0030] Embodiments of the invention include:

[0031] A pond ecological breeding method for swimming crabs, which artificially breeds swimming crabs with shrimps and shellfish in a pond, specifically comprises the following steps:

[0032] (1) Selection of ponds for farming:

[0033] Select seawater salinity between 20% ~ 35%, water depth is more than 1.5m water intake, drainage is all convenient middle and high tide area to eat sugar as the pond for cultivation, the bottom of the pond has a descending slope to the drainage valve, so There is a gentle slope with a width of 1.5~3m in the embankment around the pond;

[0034] (2) Preparatory work for breeding:

[0035] After the shrimp and crabs...

Abstract

The invention discloses a method for ecologically breeding portunus trituberculatus in ponds, wherein people breed the portunus trituberculatus, shrimps and shellfish in the ponds in a matched mode. The portunus trituberculatus, the shrimps and the shellfish are bred in a mixed mode, and a scientific ecological stereoscopic mixed breeding mode is built. Fed bait meets the growth requirement of the portunus trituberculatus, and residual bait can be used by the shrimps; besides, excreta of the shrimps and the portunus trituberculatus and smaller organic detritus can be used as bait of the shellfish, and various kinds of natural bait or artificial feed of the ponds are used to the maximum degree; due to ingestion of the shellfish, water of the breeding ponds is purified better; by means of metabolism, decomposition and assimilation, self-improvement on a water environment is facilitated, and growing speed and anti-disease ability of the portunus trituberculatus, the shrimps and the shellfish are enhanced.

Description

technical field [0001] The invention relates to the field of aquaculture methods, in particular to a culture method for polyculture of swimming crabs, shellfish and shrimps in a pond. Background technique [0002] Portunus trituberculatus, commonly known as swimming crab and white crab, belongs to Crustacea, Decapod order, Portunidae, and is an important economic crab in the coastal areas of my country. It grows rapidly and has rich breeding profits, and has become an important cultured species in coastal areas of my country. Swimming crabs generally live and reproduce at a depth of 3-5 meters, and migrate to a depth of 10-30 meters in winter, preferring to live in caves at the bottom of the sand. However, due to the overfishing of sea area fishery and the deteriorating environment, its natural resources are decreasing year by year, seriously affecting the sustainable development of the industry's economy. Contents of the invention [0003] The technical problem mainly s...
