Effect of Age on Growth of Keeled Mullet Fish Liza Carinata (Valenciennes, 1836) in Different Environmental Conditions (Wild And Lab.)
This study was carried out in the central laboratory for aquaculture research and the National Institute of Oceanography and Fisheries, Suez branch on the Keeled mullet, Liza carinata as two parts. In the first part within the wet laboratory, four treatments were formed by ratio densities 40, 60, 80, and 100 fish per cubic meter within a wet laboratory. This experiment expanded for 13 weeks. The fish fed on commercial diets 32% crude protein 6 days per week for two times as 3% of biomass weight of fish. The following parameters were measured: growth performance during the experimental period and gonadosomatic index at the end of the experiment. Results showed that females' final weight, gain weight, daily weight gain, and SGR were slightly higher than those of males. GSI ranged from 0.19±0.003 to 0.24±0.005 for females and males, respectively. The second part within wild, monthly random samples L. carinata were collected from the commercial catch of artisanal boats at Suez Bay during the period from September 2018 to September 2019. The length-frequency for more than 943 specimens of L. carinata was grouped in 1cm length classes. In the laboratory date of capture, total length to the nearest mm, total weight to the nearest 0.1g. The equation for growth in length was Lt = 22.45 (1 - e-0.52 (t +0.34)). The equation for growth in weight: Wt = 133.96 (1 - e -0.52 (t +0.34)) 3.12
