The thoracic fins are light red with 14-15 soft rays and the pelvic fins have 1 soine with 5 rays. Shark skin tanned with placoid scales on it is called shagreen. Sharks are extremely dangerous in the sea and injure fisherman and damage their nets, steal baits, devour captured fish and drive away squids and fishes to be netted. Consumer demand for tilapia and tambaqui product attributes is studied in the second essay. A Source of Protein During breeding, male fish make round holes at the edge or bottom of the pond and female fish lay their eggs here. Transgenic fish have been used to study developmental regulation of genes, improve cold tolerance, increase growth rate, and improve feed utilization. The ease of breeding and ongoing care, along with the accelerated growth and the wide variety of consumed food, have made Tilapia one of the most important fish species in the pisciculture sector. Brooder. Low carbohydrate Uses Of Tilapia As we all know tilapia is a fish that can be used in fish fry , fish curry etc. It became popular at the farmer level in the early part of the current century. An extreme case of specialisation is the bony electric eel (Electrophorus electricus) of the Amazon. Tilapia fish is a lean source of protein and also a good source of various vitamins and minerals. No special techniques are required for breeding and laying eggs. The skin of several fishes like the sharks and rays are used for making polishing and smoothing material.
