technical field

The invention relates to the technical field of aquaculture, in particular to a device and a method for cleaning up floating dirt in a squid nursery pond.

Background technique

The descriptions in this section merely provide background information related to the disclosure in this application and may not constitute prior art.

Sepiella japonica, commonly known as cuttlefish and order fish, belongs to the phylum Mollusca, class Cephalopoda, order Decapoda, family Sepiidae, and genus Sepiella . Mansoni squid was once one of the traditional "four seafoods" in the East China Sea fishing grounds in my country. The highest annual output in Zhejiang Province's history once reached more than 60,000 tons, accounting for 9.3% of the province's total marine fishing output. Since the end of the 1970s, due to overfishing and destruction of spawning grounds, the output of squid in the coastal fishing grounds of Zhejiang has dropped sharply, and the fishing season has not been formed, and it is on the verge of extinction.

Breeding and release is an effective means to increase the replenishment of fishery resources. In recent years, the proliferation and release of squid in Zhejiang Province has achieved initial results. The squid that has disappeared for many years has gradually returned to the people's table. The proliferation and release of squid in the East China Sea has become the most successful artificial breeding in the East China Sea fishery. Release case. The multiplication and release of Squid mansoni is mainly in the form of releasing fertilized eggs.

I have been engaged in the large-scale artificial breeding of squid mansoni for many years, and it has been observed that during the indoor artificial breeding of squid mansoni, there are often a large number of mucous membrane-like floating objects on the surface of the culture water. There are two main sources of this kind of floating matter, one is from the dead shrimps that are fed and the lighter residues after the squid ingested the shrimps, and the other is the jets ejected by the squids during activities such as grabbing food, fighting and mating Ink, ink is a viscous suspension composed of many small black particles. It is a kind of indole quinone substance. Part of it diffuses into the water body, and part of it will adhere to debris when it encounters debris, etc., and float on the surface of the pool. Difficult to unravel. The death of squid is mostly caused by the decay of dead shrimp pollutants, the blackening of the water caused by inkjet, and the oil film formed by ink and debris, which leads to the deterioration of the water body and insufficient oxygen supply, especially during the spawning season. .

In actual farming production, the traditional way is:

1. According to the principle of siphon, use the sewage suction pipe to siphon the residual bait at the bottom to the drainage ditch twice a day to prevent the residual bait from rotting and spoiling the water quality;

2. During the breeding period, in order to reduce the concentration of ink in the water body and maintain a good water environment, first of all, the water body should be replaced at least twice a day, about 3/4 each time; The drain hole of the sewage pipe 1 is discharged, but the efficiency is not high, and the culture water directly flows to the drain, causing great waste. The daily water exchange rate is 200%-300%. During the peak period of seedling cultivation, the seawater supply is seriously insufficient.

3. Use a ladle to remove floating objects such as ink and debris on the surface of the water body from time to time. The workload is heavy, and only piles of floating objects can be cleaned.

It should be noted that the above introduction to the technical background is only for the convenience of a clear and complete description of the technical solution of the present application, and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are known to those skilled in the art just because these solutions are described in the background technology section of this application.
