HISTOLOGICAL STUDY ON INTERNAL ORGANS DEVELOPMENT OF MANGROVE SNAPPER, Lutjanus argentimaculatus LARVAE
Abstract: Mangrove snapper,
Lutjanus argentimaculatus is one of highly economic value of marine fish
commodity. Culture of this species has been developed a few years ago. Basic
data on biological aspect is still limited whereas those kinds of information
are needed. Histological study to determine development of internal organs of
the larvae of mangrove snapper was conducted. Amount of 15-20 larvae each from
1 day after DAH hatching (1 DAH) up to 30 days after hatching (30 DAH) were
collected, fixed in Bouin’s solution for 4-6 hours and then transferred into
70% alcohol. The samples were then embedded in paraffin wax and the sections
were stained with haematoxylineosin (H&E). Results showed that the eye
retina of the mangrove snapper larvae well developed on 3 DAH, whereas their
digestive tract was on 5 DAH. Under this condition, the larvae started feeding
as showed by present of natural food tissues in the intestine. Development of
digestive tract and other internal organs reached their complete form like in
adult fish after 20 DAH.
