Takifugu rubripes, commonly known as the Japanese puffer, Tiger puffer, or torafugu (

pufferfish in the genus Takifugu. It is distinguished by a very small genome that has been fully sequenced because of its use as a model species and is in widespread use as a reference in genomics.[3]

Taxonomy and etymology

The species is often referred to in the genomics literature as Fugu rubripes. The genus Fugu is a synonym of the currently preferred Takifugu.[4] Takifugu is Japanese for puffer and rubripes comes from the Latin ruber and pēs meaning ruddy foot.[citation needed]

Distribution and habitat

The species is known from the

estuaries; young fish can tolerate a wide range of salinities and will remain in river mouths and lagoons, maturing for one year before migrating permanently to the open ocean.[1]

Genome

A feature of this species is that it has a very small

RNA genes.[6]

One type of torafugu, 22-seiki fugu (meaning "22nd-century fugu"), has been genetically modified by removing four leptin receptor genes that control appetite. The result has increased appetite and weight gain, growing on average 1.9 times faster than normal torafugu. It is sold commercially as food.[7][8]

Toxicity

As some other pufferfish, some organs of the Japanese puffer contain tetrodotoxin and are highly toxic. The toxin is highly concentrated in liver and ovaries, slightly present in the intestines and flesh, and absent from skin and testes.[1]

Conservation

The Japanese puffer is classified as

IUCN. It is one of the most valuable commercial fishes in Japan, and although current catches (101 tonnes / year in 2004, down from a peak of 2,000 tonnes in 1987) are small compared to those of many other commercial species such as sardines and anchovy, they appear to be unsustainable and prevent the recovery of the species from earlier over-exploitation. Gear restrictions (most catches occur by longline fishing) and adjustments of fishery seasons to protect juveniles have been recommended to aid recovery. The species is extensively raised in aquaculture.[1]
