Age, growth and mortality of the small scaled Terapon puta (Cuvier, 1829) in Bardawill lagoon, North Sinai, Egypt
Age, growth, and mortality of Terapon puta were studied from a small scale fishery of Bardawill lagoon, (North Sinai, Egypt). 2777 specimens (6.9 to 17.5 cm total Length and 14.1 to 55.9 g total weight), were collected from April to December, 2016. The relationship between length and weight was W = 0.0186L2.7809. Age was determined by otoliths and age groups 0 to 4 years were observed. Growths in length and weight at the end of each year were calculated. The growth parameters of von Bertalanffy equation were calculated as (L∞ = 18.50, K = 0.3554 yr-1 and t0 = -1.15 yr-1). Growth performance index was calculated (φ = 2.08 for length and φ= 0.75 for weight). Mortality rates were 0.90 yr-1, 0.35 yr-1and 0.55yr-1 for total, natural and fishing mortality, respectively. The currently exploitation rate E = 0.61. The probability of capture (Lc50 = 12.7). The higher of fishing mortality verses natural mortality observed for T. puta indicates that its stock was overexploited in Bardawill lagoon.
