Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
Herring are forage fish, mostly belonging to the family of Clupeidae.
Sardine and pilchard are common names for various species of small, oily forage fish in the herring family Clupeidae. The term 'sardine' was first used in English during the early 15th century; a somewhat dubious folk etymology says it comes from the Italian island of Sardinia, around which sardines were once supposedly abundant.
Sprat is the common name applied to a group of forage fish belonging to the genus Sprattus in the family Clupeidae. The term also is applied to a number of other small sprat-like forage fish. Like most forage fishes, sprats are highly active, small, oily fish. They travel in large schools with other fish and swim continuously throughout the day.
Peacock bass or Brazilian tucunaré are large freshwater cichlids of the genus Cichla. These are diurnal predatory fishes native to the Amazon and Orinoco basins, as well as rivers of the Guianas, in tropical South America. They are sometimes referred to in English by their Brazilian name tucunaré or their Spanish name pavon. Despite the common name and their superficial similarity, they are not closely related to other fish known as bass, such as the North American largemouth bass.
The ocellaris clownfish, also known as the false percula clownfish or common clownfish, is a marine fish belonging to the family Pomacentridae, which includes clownfishes and damselfishes. Amphiprion ocellaris are found in different colors, depending on where they are located. For example, black Amphiprion ocellaris with white bands can be found near northern Australia, Southeast Asia, and Japan. Orange or red-brown Amphiprion ocellaris also exist with three similar white bands on the body and head. Amphiprion ocellaris can be distinguished from other Amphiprion species based on the number of pectoral rays and dorsal spines. Amphiprion ocellaris are known to grow about 11 cm long. Like many other fish species, females are, however, larger than males. The life cycle of Amphiprion ocellaris varies in whether they reside at the surface or bottom of the ocean. When they initially hatch, they reside near the surface. However, when Amphiprion ocellaris enter into the juvenile stage of life, they travel down to the bottom to find shelter in a host anemone. Once they find their anemone, they form a symbiotic relationship with them.
Cichla ocellaris, sometimes known as the butterfly peacock bass, is a very large species of cichlid from South America, and a prized game fish. It reaches 74 cm (29 in) in length. It is native to the Marowijne and Essequibo drainages in the Guianas, and the Branco River in Brazil. It has also been introduced to regions outside its natural range, but some uncertainty exists over the exact identity, and at least some of the introductions may involve another Cichla species or hybrids. It is frequently confused with C. monoculus. Studies conclude that the introduction of Cichla ocellaris does not negatively impact fish communities in Florida, making it an effective fisheries management tool.
The butterfly blenny is a small marine blenniid fish of Northern and Western Europe, as well as the Mediterranean Sea and Black Sea and Morocco. It is usually found at a depth of 10–400 metres (33–1,312 ft) down, especially in areas with a rocky floor.
Pao cambodgiensis is a species of freshwater pufferfish native to the Mekong basin. It is also recorded from Dong Nai River. This species grows to a length of 15.3 centimetres (6.0 in) SL.
Pao cochinchinensis is a species of freshwater pufferfish native to the basins of the Mekong and Chao Phraya Rivers. This species grows to a length of 7 centimetres (2.8 in) SL.
Pao leiurus is a species of pufferfish found in Southeast Asia from Thailand to Indonesia and in particular the Mekong basin. It is occasionally imported into the aquarium trade but is reported to be aggressive and snappish.
An anchovy is a small, common forage fish of the family Engraulidae. Most species are found in marine waters, but several will enter brackish water, and some in South America are restricted to fresh water.
Awaous ocellaris is a species of goby native to fresh, marine and brackish waters of southern Asia from India to the Philippines, and eastern Asia to Japan as well as the islands of Oceania. This species can reach a length of 13 centimetres (5.1 in) TL. It is of minor importance to local commercial fisheries.
Pao is a genus of mostly freshwater pufferfish with one species also occurring in brackish water. They are found in Southeast Asia. Until 2013, its species were generally placed in Tetraodon.
Pao turgidus is a species of freshwater pufferfish native to the Mekong basin. It may also occur in the Chao Phraya basin in Thailand. This species grows to a length of 18.5 centimetres (7.3 in) SL.
Pao bergii is a species of pufferfish in the family Tetraodontidae. It is a tropical freshwater fish native to the Kapuas River drainage of Borneo in Kalimantan (Indonesia).
Pao brevirostris is a species of pufferfish in the family Tetraodontidae. It is a tropical freshwater species native to Asia, where it is known from the Mekong basin and the Chao Phraya drainage. It inhabits marshes and swamps with dense aquatic plant cover, and the species is known to frequently hide between roots and among submerged foliage. It can grow to 9.5 cm (3.7 in) standard length.
Ancistrus gymnorhynchus is a species of catfish in the family Loricariidae. It is a freshwater species endemic to Venezuela, where it occurs in the upper Pao River basin in the Orinoco drainage, as well as in coastal rivers of the states of Carabobo and Yaracuy in Venezuela. The species reaches 14.2 cm (5.6 in) SL and it is known to feed on algae, which it has been noted to be very efficient at removing.
Sicyopterus ocellaris is a species of goby in the family Oxudercidae. It is only known from the Nuru River, in north-eastern Papua New Guinea.
