CATDOLL : CATDOLL:Do silver carp eat feed?

Silver carp eats feed. Silver carp is a typical filter-feeding fish, mainly eating zooplankton such as rotifers, cladocerans, copepods (such as sword water fleas), and also eats some phytoplankton (such as diatoms and cyanobacteria) and artificial feed.

Silver carp's appetite is directly proportional to the water temperature. Silver carp likes high temperatures, and the most suitable water temperature is 23℃~32℃. In the hot summer, silver carp's appetite is the strongest.

If you want to raise silver carp well, you must first know the special feed for bighead carp, and at the same time add human and animal manure to improve fertility.

1. Feed

The crude protein content of artificial silver carp feed should be above 30%, and the fat content should be above 4%. The feed protein raw materials need to have a certain proportion of animal protein raw materials and plant protein raw materials. Fish meal is the best animal protein raw material, and peanut cake is the best plant protein raw material.

In terms of feed processing technology, it is best to use ultra-fine grinding for feed raw materials. It is best if 90% of the raw materials can pass through an 80-mesh sieve after grinding. This can improve the digestion and absorption efficiency and growth rate of silver carp.

In terms of feed particle size, silver carp feed is divided into powder and extruded floating feed. Silver carp with a size of less than 100g can be fed powder; silver carp with a size of more than 100g can choose extruded floating feed with a particle size of 0.3mm; silver carp with a size of more than 250g can choose extruded floating feed with a particle size of 0.5mm; silver carp with a size of more than 500g can choose extruded floating feed with a particle size of 1mm.

2. Feeding

If silver carp is co-cultured with other feeding fish, in order to improve the feeding efficiency of fish, it is recommended to feed silver carp and grass carp in different areas.

Zone feeding requires domestication to form the habit of grass carp and silver carp to eat in their respective areas.

First, feed grass carp with grass carp feed for half an hour, and then feed silver carp powder or expanded floating feed to induce feeding. The distance between the grass carp feeding area and the silver carp feeding area should be more than 20 meters. Generally, after 7 to 10 days of domestication, zone feeding can be achieved.

The feeding amount of silver carp is mainly adjusted according to water temperature, zooplankton biomass, stocking density and fish feeding conditions. The normal feeding rate of silver carp is recommended to be 0.5%~1.5%.

Silver carp is a filter-feeding fish, which feeds around the clock by constantly filtering zooplankton and other feeds in the pond water. Considering the feeding pattern of silver carp and the stocking density of the pond, it is recommended to increase the feeding frequency of compound feed, preferably 4 to 5 times a day.

The higher the stocking density of silver carp, the greater the amount of feed. It is generally recommended that in ponds with mixed grass carp, crucian carp and other fish, the stocking density of silver carp should be below 60 per mu, and less feed can be given or no feed if the source is clear; when the stocking density of silver carp reaches more than 100 per mu, it is recommended to increase the amount of feed, otherwise it will affect its growth rate.

Silver carp feeds on the surface of the water. When feeding, care should be taken to avoid waste. When scattering the feed by hand, do not feed too much each time, and the feeding speed should be slow. Each feeding time should not be less than 1 hour.
