The orange roughy (Hoplostethus atlanticus), also known as the red roughy, slimehead and deep sea perch, is a relatively large deep-sea fish belonging to the slimehead family (Trachichthyidae). The UK Marine Conservation Society has categorized orange roughy as "vulnerable to exploitation". It is bathypelagic, found in cold (3 to 9 °C or 37 to ...
The orange roughy's metabolic phases are thought to be related to seasonal variations in the fish's prey concentrations, with the inactive phase being a means to conserve energy during lean periods. Slimeheads are pelagic spawners; that is, spawning aggregations are formed and the fish release eggs and sperm en masse directly into the water.
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes (the demersal zone). [ 1 ] They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. [ 1 ] In coastal waters, they are found on or near the continental shelf, and in deep waters, they are found on or near the ...

According to FishBase about 34,800 species of fish had been described as of February 2022, [5] which is more than the combined total of all other vertebrate species: mammals, amphibians, reptiles and birds. Fish species diversity is roughly divided equally between marine (oceanic) and freshwater ecosystems.
509. 2014. Globally, fish and fish products provide an average of only about 34 calories per capita per day. However, more than as an energy source, the dietary contribution of fish is significant in terms of high-quality, easily digested animal proteins and especially in fighting micronutrient deficiencies.
