Jacksonville Aquarium and fishing reports

Food must provide fish with the elements needed to "build" their body (proteins) and the energy (from proteins, carbohydrates, and lipids) required for its smooth functioning. Feeding a fish properly ensures that it will grow satisfactorily, as well as facilitating its reproduction and helping it to combat disease. Quality and quantity are two important concepts in feeding: an aquarist must learn to avoid over-feeding and to diversify the food supply. AQUARIUM FISH DIETS AND NUTRITIONAL REQUIREMENTS With regard to fishes' feeding habits and dietary requirements, there are three main groups: - Carnivores, which feed on worms, crustaceans, insects, or other fish; - Herbivores, with a diet mainly comprising vegetable matter (plants, algae) which they graze or grind; - Omnivores, which have a very varied diet as they eat both animal prey and vegetable matter. In practice, diets are not always so easy to define. In a natural setting fish eat what th...

Aquarium fish Anatomy & Biology There are more than 30,000 species of fish, more or less evenly distributed between fresh water and sea water, and of these some 1,500 are of interest to the aquarist. Fish embody a great anatomical and biological diversity and richness, and this can be clearly seen in aquariums. Whatever type of aquarium you choose, a minimal knowledge of the anatomy and biology of the species you are raising is an essential prerequisite. The information below, presented in layman's language, allows you to keep your fish in good health, in the best possible conditions, to feed them appropriately so that they can grow, and to facilitate their reproduction — in short, to understand them better in order to take better care of them. External Anatomy of a fish The body A fish is typically drawn as an elongated spindle, and in fact this is the most common form, as it makes it easier to swim in open water. These hydrodynamic characteristics pe...
