A commercial trawl vessel was used and total 6 hauls were done to get some preliminary information on the population structure and abundance of red shrimp, Plesionika martia (A. MilneEdwards, 1883). A total of 50 specimens were sampled. The overall sex ratio, 1 male : 6.14 female, was significantly biased towards females (p<0.05). The mean carapace length (CL +/- SD) and mean weight (W +/- SD) of males and females were calculated as 59.28 +/- 14.49 mm (43-77 mm), 7.58 +/- 3.16 g (4.16-11.73 g), 73.62 +/- 9.24 mm (44-87 mm) and 12.13 +/- 3.88 g (4.5-19,7 g), respectively. Significant differences were detected between mean carapace length and weight of males and females (p<0.05). The ratios of red shrimp in the total catch and in the total shrimp catch were calculated as 5.53 % and 6.84 %, respectively. P. martia specimen were observed in the three out of six hauls. The catch per unit effort in the third haul was 4.5 kg/h, in the forth hauls was 2 specimen/h, and in the fifth haul was 2 specimen/h.trinfo:eu-repo/semantics/closedAccessPlesionika martianortheastern MediterraneanPopulation structureAbundanceArticle23365367WOS:000440355200009N/A
