Protosalanx is a small

Lake Dianchi.[1][2] In addition to being eaten locally in Asia, they are exported to southern Europe as a replacement of the more expensive transparent goby, a Mediterranean species used in the local cuisine. This replacement is often done openly, but sometimes it is done fraudulently.[3]

Protosalanx are up to 22.5 cm (8.9 in) in

estuaries to spawn and the juveniles returning to the coastal sea. However, some of the introduced populations have been able to adapt their life cycle and always stay in fresh water.[2][4]

The scientific name is derived from proto (Greek proto = first) and the latinization of salamga, Filipino for a kind of swallow.[6]

Species

There are currently two recognized species in this genus:[1]

Genome and sex-determination

The Protosalanx genome has an estimated size of 525Mb and encodes 19,884 protein-coding genes.[2] Following this initial reference, whole genomes of 20 male and 20 female Protosalanx hyalocranius were sequenced and GWAS analyses were conducted to uncover its sex determination system and putative sex‐determining genes. Indicating a ZZ/ZW sex determination system, and that a “Z dosage” effect might play a vital role.[7]
