Fish food should ideally provide the fish with fat (for energy) and amino acids (building blocks of proteins) and the fish food (whether flake or pellet) must be speedily digested in order to prevent buildup of intestinal gas, kidney failure and infections (such as swim bladder problems and dropsy) and to avoid aquarium pollution due to ...
Prior to 1910, fish meal was primarily used as fertilizer, at least in the UK. [2]Fish meal is now primarily used as a protein supplement in compound feed. [2] [3] As of 2010, about 56% of fish meal was used to feed farmed fish, about 20% was used in pig feed, about 12% in poultry feed, and about 12% in other uses, which included fertilizer. [1]
Bluegill try to spend most of their time in water from 60 to 80 °F (16 to 27 °C), and tend to have a home range of about 320 square feet (30 m 2) during nonreproductive months. They enjoy heat, but do not like direct sunlight – they typically live in deeper water, but will linger near the water surface in the morning to stay warm. [ 6 ]

They also will readily consume human food scraps, most notably bread which is commonly used for bait. [15] The pumpkinseed sunfish has a terminal mouth, allowing it to open at the anterior end of the snout. [5] Pumpkinseed sunfish that live in waters with larger gastropods have larger mouths and associated jaw muscles to crack the shells. [16]
The green sunfish (Lepomis cyanellus) is a species of aggressive freshwater fish in the sunfish family (Centrarchidae) of order Centrarchiformes.The green sunfish does not always grow large enough to be an appealing target for anglers, [2] but it is kept as an aquarium fish by hobbyists. [3]
It is dark-colored dorsally and yellow-green ventrally. Unlike bluegill, the male has a cherry-red edge on its operculum; females have orange coloration in this area. The adult fish are between 20 and 24 cm (7.9 and 9.4 in) in length. Max length is 43.2 cm (17.0 in), compared to a maximum of about 40 cm (16 in) for the bluegill.
