Hemisquilla braziliensis is a species of mantis shrimp native to South America. [1]
H. braziliensis is currently facing pressure in the South Atlantic due to bycatch and exploitation. Off the coast of the Brazilian states of Sao Paulo and Rio de Janeiro, commercial pink shrimp trawling is common and often leads to the bycatch and discarding of numerous species of crustaceans, including H. braziliensis. [2] Due to its large size, the species is also directly targeted for commercial exploitation in this region. [3]
Bycatch, in the fishing industry, is a fish or other marine species that is caught unintentionally while fishing for specific species or sizes of wildlife. Bycatch is either the wrong species, the wrong sex, or is undersized or juveniles of the target species. The term "bycatch" is also sometimes used for untargeted catch in other forms of animal harvesting or collecting. Non-marine species that are caught but regarded as generally "undesirable" are referred to as rough fish or coarse fish.
The shrimp fishery is a major global industry, with more than 3.4 million tons caught per year, chiefly in Asia. Rates of bycatch are unusually high for shrimp fishing, with the capture of sea turtles being especially contentious.
The devil fish or giant devil ray is a species of ray in the family Mobulidae. It is currently listed as endangered, mostly due to bycatch mortality in unrelated fisheries.
Mullus barbatus is a species of goatfish found in the Mediterranean Sea, Sea of Marmara, the Black Sea and the eastern North Atlantic Ocean, where its range extends from Scandinavia to Senegal. They are fished, mostly by trawling, with the flesh being well regarded. The International Union for Conservation of Nature has assessed their conservation status as being of "least concern".
The hedgehog seahorse is a species of fish of the family Syngnathidae. It inhabits coastal waters from India and Sri Lanka to Taiwan and northern Australia. It is threatened by overfishing, as both targeted catch and bycatch. This species is ovoviviparous, with males carrying eggs in a brood pouch before giving birth to live young.
Squilla mantis is a species of mantis shrimp found in shallow coastal areas of the Mediterranean Sea and the Eastern Atlantic Ocean: it is also known as "pacchero" or "canocchia". Its abundance has led to it being the only commercially fished mantis shrimp in the Mediterranean.
Farfantepenaeus is a genus of prawns in the family Penaeidae. Its eight species were formerly included in the genus Penaeus. It was first published as a genus name in 1972 by Rudolf N. Burukovsky, but without the necessary designation of a type species. That situation was corrected by the same author in 1997. The name Farfantepenaeus commemorates the Cuban carcinologist Isabel Pérez Farfante.
The common guitarfish is a species of cartilaginous fish in the family Rhinobatidae. It is native to the eastern Atlantic Ocean and the Mediterranean Sea. It is a bottom-dwelling fish feeding on crustaceans, other invertebrates and fish. The females give birth to live young. Its lifestyle makes it vulnerable to trawling and other fishing methods, populations seem to be declining and it has disappeared from parts of its range.
Pandalus montagui is a species of cold-water shrimp in the family Pandalidae. It is the type species of the genus Pandalus and is variously known as the pink shrimp, Aesop shrimp and Aesop prawn.
In the fishery business, a bycatch reduction device is a tool designed to minimize unintended capture of marine animals, to reduce the adverse effects of fishing on the ecosystem.
A shrimp (pl.: shrimp or shrimps is a crustacean with an elongated body and a primarily swimming mode of locomotion – typically belonging to the Caridea or Dendrobranchiata of the order Decapoda, although some crustaceans outside of this order are also referred to as "shrimp".
Nemipterus bipunctatus, the Delagoa threadfin bream, Bleeker's threadfin bream or butterfly bream, is a species of marine ray-finned fish belonging to the family Nemipteridae, the threadfin and whiptail breams. This demersal fish is found over soft bottoms in the Indian Ocean.
The blackchin guitarfish is a species of cartilaginous fish in the family Rhinobatidae. It is native to the eastern Atlantic Ocean and the Mediterranean Sea. It is a bottom-dwelling fish feeding on crustaceans, other invertebrates and fish. The females give birth to live young. Its lifestyle makes it vulnerable to trawling and other fishing methods, populations seem to be declining and it is subject to intensive fishing pressure, with its fins being sold into the Asian market. The International Union for Conservation of Nature has assessed its conservation status as being "critically endangered".
The Southern eagle ray, sometimes known as the Southern eagle fish or the rockfish, is a ray species in the family Myliobatidae. It lives in waters just off of the Atlantic coast, from the tip of Florida down to Argentina, inhabiting estuaries or bays to give birth during spring and summer and migrating to the open sea in autumn and winter. It has an average width of 99 centimeters, and a length of 60 centimeters. It is often confused with the bullnose ray, a related species in the genus Myliobatis, due to the two species' similarities in appearance.
Brotula barbata, commonly known as the bearded brotula, Atlantic bearded brotula, or sugarfish, is a species of cusk-eel in the genus Brotula. It lives in the Atlantic Ocean, in depths of up to 300 meters. Its coloring ranges from olive-brown to red-brown, and it grows up to be around 50 centimeters. It has a carnivorous diet, and it is oviparous.
Acetes americanus is a small shrimp species in the family Sergestidae found in the western Atlantic Ocean between Brazil and the United States.
Hemisquilla is a genus of mantis shrimp, and the only genus in the family Hemisquillidae. It contains four species distributed in Australia and the Americas. Species in the genus typically eat snails, fish, rock oysters, and smaller crustaceans like crabs. They are preyed upon by larger bony fishes and cephalopods. It is the most basal living mantis shrimp lineage, and the sister group to all other mantis shrimp.
Hemisquilla ensigera is a species of mantis shrimp. Two formerly recognized subspecies are now considered to be separate species.
The Rio Grande marine ecoregion covers the waters offshore of the southern Brazilian states of Rio Grande do Sul and Santa Catarina. The ecoregion stretches along 500 miles of sandy beach coast, and 200 miles out to sea. The warm Brazil Current flows south through the region in parallel with the coast. The continental shelf is smooth and flat, with the bottom mostly sand and mud. Overfishing is a problem, but marine life in recent years has benefited from measures such as a 2018 ban on motorized shrimp trawler fishing within 12 miles of the Rio Grande do Sul coast. The Rio Grande ecoregion is one of four coastal marine ecoregions in the Warm Temperate Southwestern Atlantic marine province. It is thus part of the Temperate South America realm. .
