Can hydrangea be added to feed instead of fish meal?

Yes, people studied black hydrangea to find feed protein instead of fish meal. Fish meal is a very important nutrient in fish feed, which provides protein and fat for fish growth. Therefore, in order to save costs, it is not advisable to reduce the amount of fish meal. At present, soybean meal is also used to replace part of fish meal in fish feed, but fish prefer to eat animal protein and fat, and plant protein and fat are less attractive to fish. Feeding omnivorous aquatic fish with black water salamander larvae instead of fish meal can not only provide fish with protein and fat, but also reduce the cost of fish feed.
