Fishmeal in the context of "Fish feed"

The common stingray (Dasyatis pastinaca) is a species of stingray in the family Dasyatidae, found in the northeastern Atlantic Ocean and the Mediterranean and Black Seas. It typically inhabits sandy or muddy habitats in coastal waters shallower than 60 m (200 ft), often burying itself in sediment. Usually measuring 45 cm (18 in) across, the common stingray has a diamond-shaped pectoral fin disc slightly wider than long, and a whip-like tail with upper and lower fin folds. It can be identified by its plain coloration and mostly smooth skin, except for a row of tubercles along the midline of the back in the largest individuals.

The predominant prey of the common stingray are bottom-dwelling crustaceans, though it also takes molluscs, polychaete worms, and small bony fishes. It is aplacental viviparous: the embryos are nourished by yolk and later histotroph ("uterine milk") produced by the mother. Females bear 4–9 young twice per year in shallow water, after a gestation period of four months. The common stingray can inflict a painful, though rarely life-threatening, wound with its venomous tail spine. During classical antiquity, its sting was ascribed many mythical properties. This species is not sought after by commercial fisheries, but is taken in large numbers as bycatch and utilized for food, fishmeal, and liver oil. Its population is apparently dwindling across its range, and the International Union for Conservation of Nature (IUCN) assesses it as Vulnerable.

Boilies are a type of artificial fishing bait made from boiled paste that usually consists of fishmeals, milk proteins, bird foods, semolina and soya flour, which are mixed with egg white as a binding agent. The mixture is then boiled to form hard, round balls that diffuse evenly and slowly in water, and additional flavourings and aromatic attractants are usually included in the mixture to enhance the olfactory appeal to the fish. The spherical shape also allows the baits to be catapulted accurately when fishing at distant waters.

Though boilies are typically made and sold by large commercial suppliers, many anglers opt to make their own unique homemade boilies.
