What does the death of whiteleg shrimp fry look like?It looks like a dead shrimp, nothing special! In most cases, the surface of the shrimp fry turns white when they just die, and they are somewhat different from adult shrimps when viewed with the naked eye. Because the shrimp fry are too small, their shells are generally transparent, and only their intestines can be seen to be black. Most shrimp fry do not eat before they die, and their intestines are empty, just like what land-based farmers call an empty stomach. Therefore, the shrimp fry look white when they first die, and their binucleate eyes also appear grayish white. What does desalinated shrimp fry mean? (Penaeus vannamei)The shrimp fry of Penaeus vannamei is cultivated in seawater with a concentration of 26-28‰, so the breeding environment is also in the same seawater. Due to the nationwide promotion of Penaeus vannamei, freshwater breeding of Penaeus vannamei has also become a reality. At this time, the shrimp fry cultivated in seawater must be artificially domesticated and finally fully adapted to freshwater breeding. The cultivated shrimp fry are desalinated shrimp fry. This technology was applied as early as the late 1990s. Now desalinated breeding of Penaeus vannamei has been realized in most parts of my country, and the results are remarkable. |
