What are the key factors that restrict and influence the cultivation of mariculture seedlings and the construction of marine pasture?

The natural environment is unfavorable and the feed is malnourished.

1, unfavorable natural environmental conditions. The cultivation of mariculture fry and the construction of marine pasture need the quality and nutrition of mariculture, but the ammonia nitrogen of microorganisms in most seawater exceeds the standard, which restricts and affects the cultivation of mariculture fry and the construction of marine pasture.

2, feed malnutrition. Mariculture seedlings often take crops as the main source of nutrition, and the nutritional components will not meet the needs of the population, so there is no accurate breeding and nutritional intake.
