GROWTH AND SURVIVAL PERFORMANCE OF MUSSELS (Mytilus galloprovincialis, LAMARCK 1819) INTEGRATED TO A FISH FARM
Project no. 1062 · Status: Kapanmış · 2018
Summary
In this study, mussels were integrated into a fish farm located in Balıklıova/İzmir in order to use the nutrients arising from the production activities in fish farms between April 2018 and April 2019 in the cultivation of mussels fed by filtering the water. The impact area of the fish farm was tried to be determined and the rearing, survival and reproduction performances of the mussels were examined in 3 stations, which were the farm center, the impact area and the unimpact area. In order to determine the environmental parameters, temperature, salinity, chlorophyll-a and particulate matter were measured monthly. Monthly taken mussel samples were brought to the laboratory at Ege University Faculty of Fisheries Urla Campus, biometric measurements were made, meat yield and condition indices were calculated and gonad development stages were examined. It was determined that the growth in the impact area station was statistically significant than the other two stations (P<0,05) and the mussels with an average initial length of 10 ± 0.64mm reached a final size of 61.36 ± 4.2mm at this station. The mussels in the study area are in the resting phase in the summer months; it was determined that as the water temperature decreases in October and November they became sexually active and spawning occurs during the winter period covering December, January, February and March.
