The breeding season and spawning times can be shifted thus expanding the seasonal range of production. This leads to more efficient aquaculture because fry are available to the market year round. [5] Hormonal treatments can advance spawning by two to three weeks. [5]
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
The breeding aquarium for the rummy-nose tetra, in addition, needs to be sterilised prior to use, as the fish produces eggs that are notoriously sensitive to bacterial and fungal infection. Use of an antifungal agent is strongly advised once spawning is completed in order to prevent various fungi from attacking the eggs.
However, most fish do not possess seminiferous tubules. Instead, the sperm are produced in spherical structures called sperm ampullae. These are seasonal structures, releasing their contents during the breeding season, and then being reabsorbed by the body. Before the next breeding season, new sperm ampullae begin to form and ripen.
A fish hatchery is a place for artificial breeding, hatching, and rearing through the early life stages of animals—finfish and shellfish in particular. [1] Hatcheries produce larval and juvenile fish , shellfish , and crustaceans , primarily to support the aquaculture industry where they are transferred to on-growing systems, such as fish ...
The Taiwanese ornamental fish and shrimp industry is significant with more than 250 commercial operations, ~200 of them with operations in Pingtung County. Taiwan was once known as the “cichlid kingdom” for its specialization in cichlids , a fad which culminated in the breeding of the blood parrot cichlid in 1986. [ 18 ]
The fish schools in coastal waters and ascends up the rivers (anadromous) for around 50 – 100 km to spawn during the southwest monsoons (June to September and January to April). Actual peak breeding season of the fish is a topic of debate amongst the researchers. [11]
The breeding season is when seasonal breeders reproduce. Various variables can affect when it occurs. [3] A primary influence on the timing of reproduction is food availability. Organisms generally time especially stressing events of reproduction to occur in sync with increases in food availability.
