Embodiment Construction

[0016] a. At the beginning of May every year, when the seawater temperature is 19-25°C, select the female broodstock of Mantis shrimp with full ovaries and fertilization, that is, select the gonads to fill the entire back (the front end starts from the back of the stomach and extends back to the telson). , the abdomen is orange-red, the telson part is triangular, the body length is more than 100 mm, the gonad index is 13.5-14.7%, the body surface has no mechanical damage, the appendages are complete, the body surface is shiny, and the ovaries are fully developed. Put them in the pre-disinfected holding pond (cement pool) for temporary cultivation for 2 to 3 days, add filtered fresh seawater to the holding pond, inflate it, and put the disinfectant for breeding into the temporary holding water body to prevent bacterial infection EDTA (5ppm) and oxytetracycline (1ppm), feed minced meat of variegated clams every day, the feeding amount is 8-12 kg / ha, and the temporary stocking den...

Abstract

The invention discloses an oratosquilla pond ecological breeding method which is simple in operation and low in cost, saves power consumption and can breed a great quantity of young oratosquilla for releasing and propagating; the method is implemented by selecting female parent oratosquillas which have fully-developed ovaries and are fertilized, placing in a temporary breeding pond for 2-3 days of temporary breeding, and feeding minced short necked clam everyday; selecting healthy individual and placing in a pond on mud flat with breeding density being 3000-4000 per hectare, and before the parent oratosquillas lay eggs, adding fermented chicken manure fertilizing water into the breeding pond with the addition amount being 150kilo / hectare; during the period that the parent oratosquillas lay eggs and incubate the eggs, feeding minced short necked clam everyday with feeding amount being 4-6kilo / hectare, and after eggs are incubated into the young, fishing out the parent oratosquillas; and when the young oratosquillas develop into zoaea V period young, feeding frozen red acete chinensis with feeding amount being4-6kilo / hectare to breed the oratosquillas in I period of grown young, andfishing out the young oratosquillas.

Description

Technical field: [0001] The invention relates to a method for raising seedlings of mantis shrimp, in particular to an ecological seedling raising method for mantis shrimp ponds with simple operation, low power consumption, low cost, and the ability to cultivate a large number of seedlings of mantis shrimp for release and proliferation. Background technique: [0002] Although mantis shrimp is not as famous as prawns and lobsters among the economical shrimps, it has become more and more popular among consumers because of its delicious meat and wide range of comprehensive utilization. The economic value is increasing year by year, and its development efforts are also increasing. increase. However, because the mantis shrimp is an excellent wild species with high economic value, there is no precedent for artificial cultivation, and the current disorderly fishing of its counterparts has led to a decline in the resources of the wild mantis shrimp. Invention content: [0003] The...
