Silver pomfret ( Pampus argenteus ) was a demersal fish of the family Stromateidae and high economical value. The fish was caught by the mini trawler. This research aims to study the reproductive biology, growth and mortality of silver pomfret in North Kalimantan. The research was conducted in January-November 2016 in Tarakan, North Kalimantan. The length of the silver pomfret was 9.5-32 cmFL, sex ratio between female and male was unbalanced (0,55:1). The peak of spawning season in January and august. The fecundity of silver pomfret ranges from 57,969 – 248,520 eggs and the spawning type was a multispawner. length weight relationship was negative allometric. Length at first captured (Lc) was smaller than length at first matured (Lm). The Von Bertalanffy’s growth equation was Lt = 36.6 (1-e 0.51 (t +-0.30274) ). The natural mortality rate (M) of silver pomfret was smaller than fishing mortality rate (F).
