摘要

利用2014年1 - 12月在Myeik近岸海域采集的拖网渔业渔获物，研究了splendens Leiognathus的生殖生物学。全年都有产卵，高峰期在4 - 5月和9 - 12月。初熟体长雄性为9.0 cm，雌性为8.4 cm。平均性腺指数在女性(2.5)比男性(1.5)更显著。性别比(1雄:1.1雌)也表明雌比雄占优势，产卵量在6120 ~ 58412个之间。生殖力与鱼长、鱼重和子房重的关系表明，生殖腺重(r=0.9)与生殖腺重的关系大于与鱼长(r=0.8)和鱼重(r=0.7)的关系。

Reproductive Biology of Splendid Ponyfish Leiognathus splendens (Cuvier, 1829) in Myeik Coastal Waters, Myanmar

Reproductive biology of Leiognathus splendens was studied by using the samples collected from the catches of trawl fisheries in Myeik coastal waters during January to December 2014. Spawning takes place throughout the year, with a peak during April-May and September-December. The observed length at first maturity was 9.0 cm total length in males and 8.4 cm in females. The mean gonadosomatic index was more prominently in females (2.5) than males (1.5). Sex ratio (1 male: 1.1 females) also indicates the general dominant of females over males Fecundity varied from 6120 to 58412 eggs. Relationship of fecundity to fish length, fish weight and ovary weight showed that fecundity is more related to the gonad weight (r=0.9) than length (r=0.8) and weight of fish (r=0.7)
