Recreational fishing in coastal areas plays an important role in the economic development of Turkey. In this study, non-market economic value of recreational fishing activities by using Contingent Valuation (31,500 Turkish Liras: TL) and Travel Cost (504,000 TL) Methodologies was calculated in Ordu Province. The factors affecting the respondent's Willingness-to-Pay via Tobit Regression Model and the factors affecting individual travel cost via Negative Binomial Model was assessed. Beside determining non-market benefits, socioeconomic, demographic and fishing dimensions of recreational fishermen were also queried to provide better understanding of recreational fishing profile. In conclusion, it was determined that recreational fishing in Ordu has economically big impact in the region.

The present study was carried out to evaluate the biological characteristics of Pachygrapsus marmoratus in the southern Black Sea, Ordu, Turkey. A total of 1503 crabs, ranging from 0.9 to 4.3 cm in carapace length (CL), were collected monthly from November 2012 to October 2013. Female:male ratio was found to be 1:1. Measured male and female crabs were grouped in 0.49 cm CL class intervals. The mean CL, carapace width (CW) and weight (W) were determined as 2.55 ± 0.02 cm, 2.90 ± 0.02 cm and 14.21 ± 0.27 g, respectively, for all individuals. Correlation analysis was also conducted to reveal relationships between size parameters for males and females as well as between egg number and size. The b values of CW and W for male, female and ovigerous crabs were found to be 3.1, 3.06 and 2.95, respectively. Number of large-sized individuals and growth rate was higher in males compared to females.The highest correlation was found between CW and CL in both sexes. The mean condition index values were calculated as 49.03 for males and 45.79 for females. Ovigerous females were observed only from May to July 2013. The fecundity estimates ranged from 8989 to 151,578 eggs/crab, with an average value of 57,814.53 ± 3349 eggs/crab. The egg diameter ranged between 328.40 μm and 423.38 μm, with a mean size of 365.83 ± 1.97 μm. There was a positive relationship between egg number and female size.
