  In this study, age, sex compositions, mortality, age-length, age-weight, length-weight relations, condition factors monkey goby, Neogobius fluviatilis (PALLAS, 1814), were determined from 622 specimens between April 2006 and March 2007 caught in Manyas Lake, in the Northwest of Turkey. The age compositions of specimens were between 1-5 years and sex percentages were found as 41.64% for females and 58.36% for males. The total length varied between 5.80 and 15.60 cm and the weight ranged from 3.80 to 47.20 g. Growth of population was the most rapid at the first year of life afterwards growth ratio was slower. Growth were expressed in length and weight and the von Bertalanffy growth equations were found as, Lt = 22.89 (1- exp -0.489 ( t + 1..390 ) ) and Wt = 99.85 (1- exp -0.489 ( t + 1.390) ) 2.9848 The following equation is for length-weight relationship, W = 0.127 TL 2.9848, R2 = 0.8763. Weight increased allometrically for all sexes as seen b = 2.9848. It was determined that the average condition factors of ages are changed between 1.192 and 1.283 for females and 1.225 and 1.458 for males. The population has shown better growth performance than others habitats because of the lake low latitude. We have given the population parameters and characters from Northwestern part of Anatolia in Manyas Lake.

  In this research, age, sex compositions, mortality, age-length, age-weight, length-weight relations, condition factors of white bream, Blicca bjoerkna (L., 1758), were determined from 183 specimens between April 2002 and March 2003 caught in Uluabat lake, in the northwest of Turkey. The age compositions of specimens were between 1-7 years and sex percentages were found as 50.27% for females and 49.73% for males. The mean forked length varied between 8.35 and 17.85 cm while mean weight ranged from 9.56 to 122.68 g. Growth of population was the most rapid at the first years of life afterwards growth ratio was slower. The weight of white bream increased allometrically for all sexes as seen b = 2.58. It was determined that the average condition factor of ages was between 1.62 and 2.51. The population has shown better growth performance than other habitats because the lake is low in latitude. We have given some of the population parameters and characters from Uluabat lake in northwestern part of Anatolia.

  The seasonal pattern of recruitment of the mussel, Mytilus galloprovincialis, on artificial collectors, situated at four different depth (0.5, 4, 8, 12 m) in the Dardanelles. The presence of pediveliger mussels throughout the year and their abundance in march reflects the presence of spawning mussels throughout the year and the occurence of a major spawning period during beginning of spring. Different densities of mussel settlement were detected at the different depths. Mussel seed density was higher at 0.5 m (surface) and 4 m than 8 and 12 m throughout the year. Artificial collectors should be hung within the first 8 m (especially within 4 m) of the water column in order to exploit the highest settlement in the upper parts.

  In this study, the acute toxicity of lambda-cyhalothrin, a synthetic pyrethroid pesticides heavily used in the paddy fields, to the juvenile and adults of Astacus leptodactylus was investigated. The two different experiments, one for the juvenile (0.417±0.001 g) and one for the adult (39±2.2 g) crayfish were conducted. Acute toxicity tests was performed in 3 L glass jars for the juvenile and in aquariums for the adults. Acute toxicity tests with a static control and 6 different concentrations with 3 replications were tested. About 10 healthy individuals were placed in each. During the experiments, the water temperature was kept at 20°C and average pH was constant at 7.8. At the end of the 96 h experiments, the LC50 value of lambda-cyhalothrin insektisitinin for Astacus leptodactylus were found as 0.84 ng L-1 for the juveniles and as 0.207 mg L-1 for the adults. As a result, the heavily used lambda-cyhalothrin in the paddy fields was determined to be very toxic for juveniles and for adult of Astacus leptodactylus.
