Tropical; 30°N - 11°S, 47°E Indo-West Pacific: from Kuwait to southern India and Bay of Bengal to the Philippines, also eastern tip of Papua New Guinea. Often confused with Sardinella gibbosa in Indian waters. Length at first maturity / Size / Weight / Age. Maturity: L m , range 11 -? cm. Sardinella marquesensis (Berry & Whitehead, ) Sardinella melanura (Cuvier, ) Sardinella neglecta (Wongratana, ) Sardinella richardsoni (Wongratana, ) Sardinella rouxi (Poll, ) Sardinella sindensis (Day, ) Sardinella tawilis (Herre, ) Sardinella zunasi (Bleeker, ). Habitat and Biology: Coastal,pelagic,but tolerant of low salinities in estuaries, schooling, preferring waters of 24° C, at surface or at bottom down to 50 m, strongly on a variety of small planktonic invertebrates, also fish larvae and phytoplankton. Inhabits lakes. This is the only species of Sardinella that is apparently found only, or even mainly, in freshwater. Presumably schooling. Also caught using ring nets (Ref. ).Mainly caught by gill net, beach seine, ring net and motorized push net (Refs, , ).Eaten fresh or dried (Ref. ).Is threatened by overfishing (Ref. ).
Forms schools in coastal waters. Adults feed on phytoplankton and zooplankton (crustacean and molluscan larvae) (Ref. , ).Juveniles predominantly prefer crustaceans expanding to include phytoplankton in the diet as their length increases (Ref. ).Marketed fresh, dried-salted, boiled or made into fish balls. SUMMARY: The reproductive biology of round sardinella, Sardinella auritaValenciennes, , was studied for the first time in the north-eastern Mediterranean Sea. Round sardinella has gained much attention lately because of its biomass increase, which might be the result of climatic changes occurring across the Mediterranean Sea. Monthly. Eastern Indian Ocean: Phuket, Thailand; southern coasts of East Java and Bali; and Western Australia. Western Pacific: Java Sea, Philippines, Hong Kong, Taiwan Island, southern Japan. Can not be distinguished as yet on morphological grounds from Sardinella aurita which occurs in the Atlantic Ocean. Indian Ocean: northern and western parts only, Gulf of Aden, Gulf of Oman, but apparently not Red Sea or the Persian Gulf, eastward to southern part of India, on eastern coast to Andhra; possibly to the Andaman Islands. Thus, studies pertaining to this species from the Philippines or Indonesia probably refer to Sardinella lemuru.
The species S. aurita, lives in the tropical and subtropical regions of the eastern Atlantic and is found in large concentrations along the West coast of Africa in three main areas (Roy et al., ): between southern Morocco (Western Sahara) and Guinea (26°–10° N), between Côte d’Ivoire and Ghana (7°–5°N)and further south between Gabon and southern Angola (0°–18° S) (Froese and. Dorsal spines (total): 0; Dorsal soft rays (total): ; Anal spines: 0; Anal soft rays: 12 - Diagnostic features as for Sardinella aurita from which it differs in having the anterior gill rakers on the lower limbs of the second and third gill arches distinctly curled downward (more or less flat in S. aurita) (Ref. ).The pelvic fin ray count of i 8 distinguishes S. brasiliensis from. Background and Objective: Sardinella sp. has gained much attention lately because of its biomass increase, which might be the result of climatic changes occurring across the Atlantic sea. Little information is known about reproduction of these species particularly in the Moroccan Atlantic area. The objective of the this study was to explore some aspects of the reproductive biology of. The reproductive biology of round Sardinella has been thoroughly studied in the Western8,9 and Eastern Atlantic10, In contrast, information were limited for the Atlantic Moroccan coast and it has been studied across its Mediterranean distribution. Such as the study of reproduction of Sardinella aurita in Algerian12,13, Tunisian waters14 and.
