| Abstract: |
Total of 6035 horse
mackerel, Trachurus trachurus
L. 1758, found in the Black Sea, caught by
various types of fishing gear, as purse seines, bottom trawls, gillnets,
mid-water trawls and fishing lines had been examined during January to December
2003. Length, weight, sex distribution, the ratio of fish under the minimum
legal landing size and distribution of juvenile fish and the types of gear used
were compared as a part of the study. Mean total lengths of the horse mackerel
caught using all these types of fishing gear (purse seines, bottom trawls,
gillnets, mid-water trawls and fishing lines) are measured at 12.69, 12.01,
15.35, 13.18 and 14 centimeters, respectively. According to their sex, the
minimum mean total length and weight were measured for a purse seine at 13.34
cm and 20 g for females, 13.33 cm and 19.73 g for males. Minimum legal landing
size (MLLS) is 13 cm and the ratios of under 13 cm for purse seines, bottom
trawls, gillnets, mid-water trawls and fishing lines were measured at 60.79%,
65.04%, 9.66%, 39.14% and 20.42%, respectively. The bottom trawl and purse
seine were more capable than other fishing gear in catching juvenile fish.
