Overview

Comprehensive Description

Biology

A neotenic, pelagic species inhabiting inshore and estuarine waters, over sand, mud and eel-grass (Ref. 4343). Feed on zooplankton, especially copepods, cirripede larvae and mysids (Ref. 4343). Spawn in summer in empty bivalve shells (Ref. 35388). Probably migrate to deeper water to spawn during summer (Ref. 57814). Adults die after breeding (Ref. 4696) which does not qualify as a manifestation of semelparity but abbreviate iteroparity according to a recent study (Ref. 81039). Eggs are pear-shaped (Ref. 4696).

Life History and Behavior

Life Cycle

Single spawner, all oocytes in the ovaries grow at a similar rate (Ref. 57814). However, a recent study showed that this species breeds at least twice during its short lifespan with batches of oocytes at different vittelogenic stages in the ovary (Ref. 80139).

Wikipedia

Transparent goby

The transparent goby, Aphia minuta, is a fish species of the Gobiidae family. It is the only member of the genus Aphia.

Widespread in the Atlantic Ocean from Trondheim to Morocco, also in the Mediterranean, Black Sea and the Sea of Azov. Pelagic species, inhabits the waters with temperature 13-16°C and depth 0–97 m (usually 5–80 m), near the coasts, in the estuaries, on the sandy and muddy bottoms, in foulings.

Gastronomy

This fish is appreciated in Spain as part of the Andalusian, Catalonian and Valencian cuisines.[1] In Andalusia, where they are called chanquetes it is traditionally served deep-fried, with fried eggs and roasted or fried pepper.[2] Due to its rarity and high prize, it is being commercially replaced by some species of Chinese noodlefishes, locally called chanquete chino (Chinese chanquete), Neosalanx tangkahkeii and Protosalanx hyalocranius.[3]
