Abstract
Three specimens of apogonids species of total length 72.69, 106.28 and 110.67 mm were caught off Tuticorin at the depths of 90-100 m as a bycatch on 1st January 2013 from the commercial trawler operated from Tuticorin Fishing Harbour, Southeast coast of India. In this paper, on the occurrence of Jaydia queketti was figured and the comprehensive diagnostic features of the recorded specimens were elucidated. The species of this genus Jaydia is distributed continentally and often caught as a bycatch from shrimp or fish trawl. These species are widely distributed in New Guinea, larger islands in the Coral Sea, Australia, Arabian Sea of India and also from Africa to Japan. Nevertheless, the present observation shows the occurrence of J. queketti from the by-catch of trawl fishery operated along Gulf of Mannar, Southeast coast of India.
Highlights
Cardinalfishes (Family: Apogonidae) are small percoid species, mostly less than 100 mm; generally marine, qualitatively abundant families in the reef ecosystems and are found in estuaries and lowland freshwater bodies[1,2,3]
The genus Jaydia Smith 1961 comes under the Apogoninae subfamily and tribe Sphaeramiini (6 genera)
The present paper aims to record and spot out the presence of spotfin cardinal, Jaydia queketti (Gilchrist, 1903) and to describe about the further occurrence in the trawl bycatch of Tuticorin Fishing Harbour, Tuticorin, Gulf of Mannar, Southeast coast of India
Summary
Cardinalfishes (Family: Apogonidae) are small percoid species, mostly less than 100 mm; generally marine, qualitatively abundant families in the reef ecosystems and are found in estuaries and lowland freshwater bodies[1,2,3]. They are nocturnal; few species show parental care; where males are known for mouth brooding of eggs, and some of the species have a ventral luminous organ[1,4,5]. The tribe Sphaeramiini differs from the other apogonids in having melanophores completely blackish in the stomach and intestine, seven first dorsal spines with third dorsal spine shorter than fourth spine
