The species is intensively exploited in the area as live bait for hand lines and long lines both for professional and sport fishermen. The study area is a closed bay in western Greece with a small opening which connects it to the Ionian Sea. Longevity of the species in the study area was found to be 4+ years. Females’ total length ranged between 18 and 54 mm; for males it ranged between 16 and 58 mm. The von Bertalanffy parameters for males were L ∞ =60.30 mm, K=0.520 per year and t 0 =-0.0166 years; for females they were L ∞ =58.80 mm, K=0.621 per year and t 0 =- 0.1261 years. Overall von Bertalanffy equation parameters were L ∞ =61.05 mm, K=0.521 per year and t 0 =0.086 years. Maximum weight was estimated as 3.440 g at L ∞ based on the length-weight relationship. Mortality estimates were Z=1.510 per year, M=0.928 per year and F=0.582 per year resulting in an exploitation ratio of E=39%. Using the above values, yield per recruit was estimated at 2.97 g/year at F max levels of 0.750 per year and E opt =50%. Overall length-weight relationship was estimated as: W = 0.01589TL 2.972 , r² = 0.886. This paper contributes to the knowledge of population dynamics of the species Upogebia pusilla and in particular, growth, mortality and yield.","claims":[{"public_id":"cl_0083fc4b0965610069570d52b634430e","status":"active","text":"Females’ total length ranged between 18 and 54 mm; for males it ranged between 16 and 58
