Cobia, a warm water fish, is one of the more suitable candidates for offshore aquaculture. [1] [2] Cobia are large pelagic fish, up to 2 metres (6.6 ft) long and 68 kilograms (150 lb) in weight. They are solitary fish except when spawning, found in warm-temperate to tropical waters.
Blackfin tuna are a warmer-water fish, preferring water temperatures over 20 °C (68 °F). [6] The females release eggs into the water column to be fertilized by sperm. Fertilization of their eggs produces pelagic larvae which can be found on the surface of the water all the way to depths of 164 feet. [5] [7]
Cool water copepod assemblages have moved north because the waters get warmer, they have been replaced by warm water copepods assemblages however it has a lower biomass and certain small species. This movement of copepods could have large impacts on many systems, especially high trophic level fish. [32]
Experts offer a list of the fish that have the most health benefits — from salmon and sardines to tilapia and tuna — plus which fish to avoid and why.
This is where fish can fit in as it is lower in saturated fat than most other animal protein sources and adds to the nutritional benefits of plant-based diets." 9. Fish is highly versatile.
In California, for example, 15 fish farms produce tilapia, bass, and catfish with warm water from underground. This warmer water enables fish to grow all year round and mature more quickly. Collectively these California farms produce 4.5 million kilograms of fish each year. [161]
Fish cages containing salmon in Loch Ailort, Scotland, an inshore water. Inshore mariculture is farming marine species such as algae, fish, and shellfish in waters affected by the tide, which include both littoral waters and their estuarine environments, such as bays, brackish rivers, and naturally fed and flushing saltwater 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.
