What to eat with yellow croaker?

Yellow catfish is a commonly used fish, which is artificially cultivated in many places. Yellow catfish is an omnivorous fish, which mainly feeds on animal feed under natural conditions. The fry stage feeds on zooplankton, while the adult fish feeds on insects and their larvae, small fish and shrimp, snails and clams, and also swallows plant debris.

Yellow catfish also swallows a large number of fertilized eggs of carp, crucian carp, etc. Yellow catfish has a wide diet, and the composition of its food varies under different environmental conditions. According to the analysis of the food in the stomach and intestines of 101 yellow catfish, the food types include young fish, fish eggs, shrimps, aquatic insects, snails, aquatic plants, etc., among which shrimps appear most frequently.

Yellow catfish fry hatch 1 to 3 days, body length 5.0 to 8.0 mm, from their own yolk sac to absorb nutrition, the endogenous nutrition. 4 days later, the yolk sac basically disappears, the body length of 8.1 to 9.0 mm is the feeding stage of fry, mainly feeding on rotifers, small cladocerans and copepod larvae, 9.0 mm above the fry completely feed on external food, exogenous nutrition.

Morphological characteristics of yellow catfish:

The body is elongated and slightly stout, with the tip of the snout tilted upward toward the dorsal fin and flattened laterally at the back. The head is slightly large and flattened, with most of the dorsal part of the head exposed; the upper occipital spine is wide and short, close to the nuchal spine. The snout is blunt and rounded when viewed from the back. The mouth is large, inferior, and arc-shaped. The jaw and palatine teeth are velvety and arranged in a ribbon. The eyes are medium-sized, laterally superior, with free eye margins; the interocular space is wide and slightly raised. The front and rear nostrils are far apart.

The anterior nostril is short tubular. The nasal barbels are located at the front edge of the posterior nostril, extending to or beyond the posterior edge of the eye; there is a pair of maxillary barbels, extending backward to or beyond the base of the pectoral fin; the outer mental barbels are longer than the inner mental barbels. The gill openings are large, extending forward to the ventral surface vertically below the middle of the eye. The swim bladder has one chamber and is heart-shaped. The operculum is not connected to the gill septum. The gill rakers are short.

When breeding, there must be sufficient water, fresh water, and no pollution. Each pond should be equipped with a high-power camera. Also, the fish must be healthy and have no surface injuries. The rules must be consistent. They must be fed at fixed times and some vitamins must be fed on time. I found that if the fish have any abnormal conditions, they should be dealt with in time, and the growth of the fish should be checked every half a month.
