Black Pomfret (Parastromateus niger) is one of the most important commercial species along the coast of the Oman Sea. In this study, with the aim of an investigation some biological characteristics of Black Pomfret in coastal waters of Sistan and Baluchistan province (Oman Sea). Sampling were carried out from November to December 2020 using gillnet with mesh size of 14.7 cm and 130 black pomfret were collected and the length range of Black Pomfret was 18-45.40 cm. The range of minimum and maximum weight was 112-1900 g with a mean weight of 396.453 g in Black Pomfret. The length-weight relationship of Black Pomfret was calculated as W=0.0094TL3.2016. The results showed that the calculated value of b parameter (3.2016), which indicates the natural growth pattern of this species in Oman Sea, is positive allometric. The total length-girth relationship of Black Pomfret was calculated as Gmax=1.0555Gg+1.7124 and the optimal catch length was 29.6 cm. The L∞ was estimated at 47.3 cm. The length maturity (Lm50) of Black Pomfret was calculated to be 26.6 cm. The results show 65% of the fish caught were immature and did not have a chance to spawn. Obtaining such parameters with studies and long-term planning of these stocks and the information related to the length frequency, weight, length-weight relationships, length-girth relationships and optimum length can have a great impact on the knowledge of the stocks and fishing pressure on aquatic stocks such as black Pomfret in Sistan and Baluchistan province.
