Zebra shrimp, produced in Guangdong, has very thick lines on the body and back, heavy markings, strong texture, translucent body color, and occasional bright white spots called hoarfrost. Wild shrimp that grow in low water temperature seas have black and white patterns on their backs, just like zebras, so they are called zebra shrimp. Due to the low living water temperature, its body is relatively similar, but it is not particularly smaller than its body size, generally about three centimeters. It is very similar to tiger prawns, but zebra prawns have black stripes on their bodies, which are thinner than tiger prawns, with bright white spots in the translucent body color, and are sold abroad through Hong Kong.
1. Appearance characteristics of zebra shrimp
The body length of zebra shrimp is about three centimeters, the head and tail are bright yellow, and the head is singing. The tentacles are bright red near the base. The body starts from the waist and has a clear white fine line on the outer edge of each stripe, which is as black and white as a zebra in mammals. If it is a good quality zebra shrimp, it is very beautiful with white lines and hoarfrost on the back and head.
2. Key points for raising zebra shrimp
Zebra shrimp is a kind of shrimp that is easy to raise. Too big a problem, the water PH can be kept between 6.0-8.2, weak acid and weak alkaline water can be used, the water hardness GH can be between 2-10dGH, the temperature range is 15-28 ??, the most suitable for breeding The best temperature is between 24 and 26 ??C. Zebra shrimp are mainly omnivorous, mainly algae and plankton. They can usually be fed with nutrient-rich cooked spinach, frozen red blood worms, etc., which are extremely adaptable to water temperature. Strong and easy to feed. Can be housed with most tame lampfish, but not with large or aggressive fingerlings.
In addition, in the process of raising, it should be noted that the temperature can be low or not high. Some people have tried zebra shrimp to survive at a low temperature of 15 degrees Celsius, but they start at 30 degrees Celsius. Death occurs. The tank for raising zebra shrimp should also be large enough. When using heating rods in small tanks, special attention should be paid to monitoring temperature changes. Due to the small water body and slight deviations, extreme situations are prone to occur. The biggest advantage of using a large tank is that the water body is stable; but the water volume is large, and once a problem occurs, it is more troublesome to correct. Also, it is more laborious to fish for shrimp.
3. Reproduction of zebra shrimp
The ovary on the back of female zebra shrimp during sexual maturity will be yellow. The female shrimp will mate with the male shrimp immediately after maturity, and then the female shrimp will lay eggs, and the cherry shrimp is in vitro fertilized. The pebbles are golden yellow when the zebra shrimp tank starts to hold the eggs, and turn black or green as the eggs mature. After a few weeks, the shrimps are born, and the good quality shrimp tanks can see a little red when they are born. Because zebra shrimp are large eggs, it is relatively easy to reproduce. Unlike the small egg type Yamato algae shrimp, the reproduction process requires a soda environment and there is a cooling process. Zebra shrimp can be fed with frozen blood red worms to increase nutrition when brooding eggs. At the same time, pay attention to the water quality not too acid, so as to avoid breeding difficulties for female shrimp. Female shrimp hold eggs once a month.
It is worth noting that the zebra shrimp larvae were raised in earthen ponds after hatching and collected, and the larvae mainly fed on organic debris and unicellular algae such as Chlorella in the early stage of growth. Whether the organic debris and unicellular algae are abundant in the water body is very important to improve the survival rate of zebra shrimp larvae. If the amount of food is insufficient, cannibalism will occur. The dissection of juvenile shrimp found that there were basically no debris of zooplankton such as cladocerans and copepods in the stomach of juvenile shrimp. After 7 weeks of rearing, the average size of larvae can reach 7.6 cm.
