Most oceanic species (78 per cent, or 44 per cent of all fish species), live near the shoreline. These coastal fish live on or above the relatively shallow continental shelf. Only 13 per cent of all fish species live in the open ocean, off the shelf. Of these, 1 per cent are epipelagic, 5 per cent are pelagic, and 7 per cent are deep water. [16]
Oceanic fish inhabit the oceanic zone, which is the deep open water which lies beyond the continental shelves. Oceanic fish (also called open ocean or offshore fish) live in the waters that are not above the continental shelf. Oceanic fish can be contrasted with coastal fish, who do live above the continental shelf. However, the two types are ...
Its fish are of great and growing importance to the bordering countries for domestic consumption and export. Fishing fleets from Russia, Japan, South Korea, and Taiwan also exploit the Indian Ocean, mainly for shrimp and tuna. Endangered marine species include the dugong, seals, turtles, and whales.

The largest species is the beluga sturgeon (Huso huso) of the Caspian and Black seas, the only extant bony fish to rival the massiveness of the ocean sunfish. The largest specimen considered reliable (based on remains) was caught in the Volga estuary in 1827 and measured 7.3 m (24 ft) and weighed 1,474 kg (3,250 lb). [ 1 ]
Fishes that live in the ocean can be carnivores, herbivores, or omnivores. [4] Herbivores in the ocean eat things such as algae and flowering seagrasses. Many herbivores' diets consist of primarily algae. Most saltwater fish will eat both macroalgae and microalgae. Many fish eat red, green, brown, and blue algae, but some fish prefer other types.
Fish species are roughly divided equally between freshwater and marine (oceanic) ecosystems; there are some 15,200 freshwater species and around 14,800 marine species. [27] Coral reefs in the Indo-Pacific constitute the center of diversity for marine fishes, [ 28 ] whereas continental freshwater fishes are most diverse in large river basins of ...
