Fish, plants and microbes are three main components of aquaponics, and microbes play the bridge role of converting fish waste to plant nutrients. The three major types of modern aquaponic designs are deep-water or "raft", nutrient film technology "NFT", and media-based bed or reciprocating systems.
A fish (pl.: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and ...
Fish anatomy is the study of the form or morphology of fish. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish.

Found in warm seas, the tuna is commercially fished extensively as a food fish, and is popular as a bluewater game fish. As a result of overfishing, some tuna species, such as the southern bluefin tuna, are threatened with extinction. [5] This article is part of a series on. Commercial fish. Large pelagic.
Remora Gill, 1862. Synonyms. Echeneididae. The remora ( / ˈrɛmərə / ), sometimes called suckerfish or sharksucker, is any of a family ( Echeneidae) of ray-finned fish in the order Carangiformes. [4] Depending on species, they grow to 30–110 cm (12–43 in) long. Their distinctive first dorsal fins take the form of a modified oval, sucker ...
A robot fish is a type of bionic robot that has the shape and locomotion of a living fish. Most robot fish are designed to emulate living fish which use body-caudal fin (BCF) propulsion, and can be divided into three categories: single joint (SJ), multi-joint (MJ) and smart material -based "soft-body" design.
They have been created from several different species of fish: zebrafish were the first GloFish available in pet stores, and recently the black tetra, tiger barb, rainbow shark, Siamese fighting fish, X-ray tetra, and most recently Bronze corydoras have been added to the lineup. They are sold in many colors, trademarked as "Starfire Red ...
Fins first evolved on fish as a means of locomotion. Fish fins are used to generate thrust and control the subsequent motion. Fish and other aquatic animals, such as cetaceans, actively propel and steer themselves with pectoral and tail fins.
In biology, any group of fish that stay together for social reasons are shoaling, and if the group is swimming in the same direction in a coordinated manner, they are schooling. [1] In common usage, the terms are sometimes used rather loosely. [1] About one quarter of fish species shoal all their lives, and about one half shoal for part of ...
