Abstract

Belonging to the technical field of aquatic feed, the invention particularly relates to a special feed for freshwater aquaculture of micropterus salmoides and feeding equipment thereof. By adding an immunity enhancer and an enhancer carrier into an original feed composition system, the effects of sustained release of the immunity enhancer and safe and remarkable improvement of the fish immunity are reached. On the other hand, by combining a feed charging frame unit, a rotary sprinkling plate unit and a perforated guide plate, the feeding equipment realizes the effects of uniform water surfaceand large-range feed sprinkling, and has the advantages of simple and quick feed rotary sprinkling feeding mode, large and uniform feed feeding surface, high structural stability of itself, and convenient repair and replacement.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to a special feed for freshwater culture of California perch and equipment for feeding it. Background technique [0002] California perch is a carnivorous freshwater fish with high economic value. It has the advantages of delicious meat, no intermuscular spines and relatively low growth requirements, so the market demand is huge. On the other hand, the main components of the existing freshwater culture feed for California perch are fish meal, flour, vitamins, minerals and some antifungal agents. Although the formula is basically satisfied with nutrients, it lacks additives to improve the immunity of fish, so Relatively can increase the morbidity rate of fish school, so a kind of novel high-efficiency feed containing immunity-enhancing additive is urgently needed on the market. [0003] In addition, when California perch is fed, it is mainly based on artificial sowi...
