Embodiment 1

[0025] 1) Cleaning of the pond: remove excess silt at the bottom of the pond, disinfect the pond with 50-60cm of water inflow, and after the pond is repaired, put cement pipes and tiles on the bottom of the pond as obstacles, and enter the water after disinfection. The depth of the pond water is 90-100cm, and the fermented and sterilized farmyard manure is used as fertilizer water after the pond enters the water;

[0026] 2) Fermentation method of farmyard manure: use 15 parts by weight of straw ash, 18 parts of leaf weed powder, 8 parts of distiller's grains, 12 parts of bran, and 75 parts of chicken manure as raw materials, and add 450-600 kg of water to 1000 kg of raw materials Make fermentation broth, and add 3-5kg of EM stock solution, 1-2kg of brown sugar for anaerobic fermentation for 8-10 days;

[0027] 3) Swimming crab seedlings are generally placed in mid-to-late May, and 1-1.5 kg / mu of juvenile crabs are selected for seedling cultivation in earthen ponds; in late Ju...

Abstract

The invention relates to a method for mixed culturing of swimming crabs and palaemon carinicauda. The method belongs to the technical field of fishery industry and is characterized by comprising the following steps of (1) clearing up a pond; (3) putting swimming crab seedlings in mid-to-end of May, selecting III-period baby crabs cultivated in a soil pool, putting 1-1.5kg per mu, in the end of June, putting 1-2kg of lively-swimming egg-carried shrimps per mu, and planting submerged plant water caltrop in the bottom part of the pond for improving water quality; (4) replacing 70-80 percent of water at every 5-7 days, sterilizing in time after water replacement, and putting water quality modifying agent for one time at the second day; (5) feeding crab and shrimp mixed feed, and then feeding according to the conventional mixed culturing method of the swimming crabs and palaemon carinicauda. According to the method for the mixed culturing of the swimming crabs and the palaemon carinicauda, the nutrition is balanced, the daily demands of the swimming crabs and palaemon carinicauda can be met, the feed efficiency is high, the survival rate of the swimming crabs and palaemon carinicauda is high, the ponderal growth is quick, the immunity of crab bodies can be remarkably enhanced, and the capabilities of antibiosis and antiviral of the crab bodies are improved.

Description

technical field [0001] The invention belongs to the technical field of fishery, and specifically relates to a method for polyculture of swimming crabs and white prawns. Background technique [0002] Swimming crabs belong to arthropods. The male navel is smooth and smooth, with long claws and the shell surface is blue; the female navel has fluff, and the shell surface is ocher or spotted. The meat is rich, the fat is plump, delicious and nutritious. Every 100 grams of crab contains 14 grams of protein and 2.6 grams of fat, which has high nutritional and economic value. The white prawn is a medium-sized shrimp with a body length of 5-9 cm. The white prawn has a wide range of food habits, and the protein content is not high. No matter dead, live, fresh, rotten animal or plant feed, or organic debris It can be ingested and has a wide range of feed sources. Swimming crabs and white prawns are expensive to breed alone. Contents of the invention [0003] In view of the above-m...
