What is the situation of seawater pearl grouper black body seedlings?
Seawater pearl grouper has black body seedlings. What should you watch out for in farming? Answer: Under normal circumstances, the number of black-body plants is not large, and the contagiousness is not strong or contagious. Occasionally, there are several types of seedlings appearing black body, not a contagious disease, and it is an individual seedling during the seedling cultivation process. There are problems such as the emergence of physical immune problems or open mouth stages where no food or individual functions are poor, and it should be the elimination of normal weak seedlings. If there is a large-scale black body problem, use a microscope to see if there has been a parasitic or bacterial disease. The problem to be noticed in the grouper seedling breeding: to ensure that the feed is sufficient, feed it as early as possible every day, strive to feed it before the sun comes out, prevent the emergence of seed killing each other; pay attention to the density of stocking, try to maintain a reasonable stocking density The timing of seedlings should be reasonably arranged to separate the fish fry with different specifications to prevent the fish from eating big fish. If it is the cement pond nursery rather than the pond nursery, the water should be changed as much as possible and the feces and bait in the cement pool should be kept timely. Discharge; to prevent disease on the fry regularly.
