A, seedling facilities
South America white shrimp nursery facilities and basic similar to prawn nursery room in China. The seedling pool for fiberglass rectangle flume commonly or cement pool, volume for 10 ~ 15 cubic meters. Seedling water filter must go through 2 ~ 4 times, single cell algae cultivating water treatment more strictly. Or coal boiler heating available diesel boiler, using the method of hot water circulation. With roots blower aeration.
Second, the kind of shrimp cultivation
Central and South America to use most of South America white shrimp shrimp from natural sea fishing, but fishing shrimp must prevent essence in pod fall off. Choose healthy and free from damage, weight 50 ~ 60 grams of shrimp, with male and female ratio 1 ~ 1 to 1 in the indoor sink a keeper. Stocking density of 4 ~ 5 tail/square meters, the water temperature is 26 ~ 27 ℃ salinity thirty-three over one thousand ~ 35, daily morality of pool in water by about 50%, and aeration, the morality of pool in black shading net cover, the light in the pool to be less than 100 lux. Silkworm feeding fresh oysters, squid, frozen sand, erbium, such as the daily for erbium material is about 10% of the shrimp weight.
Three, artificial ripening pod transplantation and fine
South America white shrimp as the open type of spermatheca. Its reproductive habit is different from penaeus chinensis. Male and female shrimp gonad fully mature before mating. When mating, the male shrimp fine pod adhesion in female shrimp from the chest to step foot between 3 ~ 4 (spermatheca position), a few hours after mating, the female shrimp began to lay eggs, pure pod release sperm at the same time, the complete fertilization in the water.
In South America is engaged in the South America white shrimp artificial seedling, mostly take shrimp let its natural mating ways, then pick mated female shrimp, eggs hatch in the hatching trough or cement pool. This way, although able to mass produce shrimp seedlings, but need more kinds of shrimp. In central and South America, South America white shrimp are adopting artificial ripening, fine pod artificial seedling transplant technology, the effect is better also. Operating technology are as follows: from natural sea area collection of shrimp, after a period of time a keeper for their it ADAPTS to the environmental conditions of the pool, namely artificial crowded eye operations, first will be a keeper of shrimp within the black barrel out into the air. The male and female shrimps are crowded to the ball in the right eye, again the appropriate operating in the water. And then will go to the eye of the kind of shrimp back into the original pool to continue to develop. Then through a period of time temporarily, to eyeball shrimp will gradually mature, artificial transplant fine pod at this time. South America white shrimp open spermatheca lies between 3 ~ 4 step on the foot. Sexual maturation of male shrimp, the seminal vesicle has milk-white. Artificial graft pod, must choose the male shrimps with high maturity, in the fifth step on the foot base thumb several jog, pod is out. Then fine pod adhesion in the female shrimp spermatheca. Female shrimp into the small black barrel again carefully, for its eggs, fertilization. Your barrel for smaller, fall off in case the essence of pod. Want to use black shading net shading on the barrel
