Acetes is a genus of small shrimp that resemble krill, which is native to the western and central Indo-Pacific, the Atlantic coast of the Americas, Pacific coast of South America and inland waters of South America. Although most are from marine or estuarine habitats, the South American A. paraguayensis is a fresh water species. [1] Several of its species are important for the production of shrimp paste in Southeast Asia, including A. japonicus , which is the world's most heavily fished species of wild shrimp or prawn in terms of total tonnage [2] and represent the majority of non-human animals killed for food in terms of number of individuals. [3]
In Southeast Asia, Acetes have different local names depending on the country. It is known as rebon in Indonesia, geragau in Malaysia, bubuk in Brunei, alamang in the Philippines, among others.
The genus is characterised by the loss of the fourth and fifth pairs of pereiopods. [4] [5] They are small prawns, 1–4 centimetres (0.39–1.57 in) long, translucent, but with a pair of black eyes, and a number of red spots of pigment on the uropods. [5]
The eggs of Acetes are green. As they develop, they swell to twice their original size or more. [6] The eggs hatch early in the year, and the larvae grow, mature and spawn in the same year. [7]
It includes 14 species, [8] which are listed here with their FAO endorsed common names: [9]
Many species of Acetes are fished for commercially, and the different species are often not discriminated. Acetes are the most fished genus of crustacean, with global production in 2008 of 558,124 tonnes (1.23×109 lb). [10] Fishers mostly use push nets and bag nets, as well as seines both on boats and from the shore.
Only a small proportion of the entire catch is sold fresh, with most of it being dried, salted or fermented. [5] The caught prawns are washed and then mixed with 4–5 pounds (1.8–2.3 kg) of salt per 100 lb (45 kg) of prawns. The prawns are then crushed using cleavers and packed into various containers, where the paste remains for around 4 hours. After this, the paste is re-packed, before being left to mature for a month, after which it is mixed and crushed again, and then packed for sale. If a producer cannot sell the paste quickly, it can be kept for up to 6 months, mincing it every month or so. [11] The resulting paste is reported to contain 16.2% protein and 1.3% fat. [12]
The Caridea, commonly known as caridean shrimp or true shrimp, from the Greek word καρίς, καρίδος, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp.
Dendrobranchiata is a suborder of decapods, commonly known as prawns. There are 540 extant species in seven families, and a fossil record extending back to the Devonian. They differ from related animals, such as Caridea and Stenopodidea, by the branching form of the gills and by the fact that they do not brood their eggs, but release them directly into the water. They may reach a length of over 330 millimetres (13 in) and a mass of 450 grams (1.0 lb), and are widely fished and farmed for human consumption.
Bagoóng is a Philippine condiment partially or completely made of either fermented fish or krill or shrimp paste with salt. The fermentation process also produces fish sauce known as patís.
Pandalus borealis is a species of caridean shrimp found in cold parts of the northern Atlantic and northern Pacific Oceans, although the latter population now often is regarded as a separate species, P. eous. The Food and Agriculture Organization refers to them as the northern prawn. Other common names include pink shrimp, deepwater prawn, deep-sea prawn, Nordic shrimp, great northern prawn, northern shrimp, coldwater prawn and Maine shrimp.
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.
Shrimp paste or prawn sauce is a fermented condiment commonly used in Southeast Asian and Southern Chinese cuisines. It is primarily made from finely crushed shrimp or krill mixed with salt, and then fermented for several weeks. They are either sold in their wet form or are sun-dried and either cut into rectangular blocks or sold in bulk. It is an essential ingredient in many curries, sauces and sambal. Shrimp paste can be found in many meals in Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam. It is often an ingredient in dip for fish or vegetables.
Cryphiops caementarius is a South American freshwater shrimp.
Palaemon serratus, also called the common prawn, is a species of shrimp found in the Atlantic Ocean from Denmark to Mauritania, and in the Mediterranean Sea and Black Sea.
Scyllarides latus, the Mediterranean slipper lobster, is a species of slipper lobster found in the Mediterranean Sea and in the eastern Atlantic Ocean. It is edible and highly regarded as food, but is now rare over much of its range due to overfishing. Adults may grow to 1 foot (30 cm) long, are camouflaged, and have no claws. They are nocturnal, emerging from caves and other shelters during the night to feed on molluscs. As well as being eaten by humans, S. latus is also preyed upon by a variety of bony fish. Its closest relative is S. herklotsii, which occurs off the Atlantic coast of West Africa; other species of Scyllarides occur in the western Atlantic Ocean and the Indo-Pacific. The larvae and young animals are largely unknown.
Heterocarpus is a genus of deep-sea shrimp, mainly of tropical areas all over the world.
Marsupenaeus is a monotypic genus of prawn. It contains a single species, Marsupenaeus japonicus, known as the kuruma shrimp, kuruma prawn, or Japanese tiger prawn. It occurs naturally in bays and seas of the Indo-West Pacific, but has also reached the Mediterranean Sea as a Lessepsian migrant. It is one of the largest species of prawns, and is accordingly one of the most economically important species in the family.
Trachysalambria curvirostris is a species of prawn that lives in shallow waters of the Indo-West Pacific. It is one of the most important species targeted by prawn fishery, with annual harvests of more than 300,000 t, mostly landed in China.
Ibacus ciliatus is a species of slipper lobster from the north-west Pacific Ocean.
A shrimp is a crustacean with an elongated body and a primarily swimming mode of locomotion – typically belonging to the Caridea or Dendrobranchiata of the decapod order, although some crustaceans outside of this order are also referred to as "shrimp".
Prawn is a common name for small aquatic crustaceans with an exoskeleton and ten legs, some of which are edible.
Farfantepenaeus aztecus is a species of marine penaeid shrimps found around the east coast of the US and Mexico. They are an important commercial species in the US. The FAO refers to them as the northern brown shrimp; other common names, used in the US, are brown shrimp, golden shrimp, red shrimp or redtail shrimp.
Farfantepenaeus duorarum is a species of marine penaeid shrimp found around Bermuda, along the east coast of the United States and in the Gulf of Mexico. They are a significant commercial species in the United States and Cuba.
Crustaceans are invertebrate animals of the subphylum Crustacea, a large, diverse group of mainly aquatic arthropods including decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans.
Acetes japonicus is a shrimp species from the family Sergestidae. It occurs in the western Pacific Ocean and northern Indian Ocean, between Arabian Sea and the Yellow Sea. It is the species of wild shrimp or prawn with the highest reported annual catch, 402 thousand tonnes in 2019, fished by China and South Korea.
The eastern king prawn is an edible dendrobranch prawn endemic to eastern Australia. Its scientific name is Melicertus plebejus or Penaeus plebejus. It is caught by commercial and recreational fishers for human food.
