Contributions Concerning the Quality Indices' Appreciation in Main Aquatic Organisms, Which Fall Under Human Consumption

Abstract

"One-year old rope grown mussels (Mytilus galloprovincialis L.) were held in three experimental lantern nets in raft system outside of Sinop Harbour. Mortality and growth were monitored from May 2005 to May 2006. Water temperature, salinity, transparency and food availability (total particulate matter, particulate organic matter, particulate inorgnic matter and Chlorophyll-a) were also determined. The monthly specific growth rate (SGR%) ranged 1.50-5.72% with a mean of 2.59±0.30%. Shell length increment was found as 13.67 mm and reached to 51.20±0.50 mm. The live weight increment was found 7.91 g, and mussels reached to 12.61±0.39 g. Meat yield ranged from 17.51 to 24.25% with a mean of 21.12±0.63%. Cumulative mortality was higher in winter than spring and summer. Monthly mortality was found maximum with 5.2% in October. This study is the first known experiment to collect data on effect of environmental factors on mussel growth and natural mortality in lantern nets and raft system in the Black Sea."
