| dc.description.abstract | The study was carried out to know the efficiency of the bridle lengths and it was attached in between otter boards and wings of the trawl net. The experimental study was carried out once in the fortnight for the depth of 20 m and 25 m with a bridle length of 15 m and 20 m for the respective depths. It was observed that, during trawling square mesh codend covered with diamond mesh i.e. 24 mm to know the retained and escapement catch composition as well as the fuel consumption in both the bridle lengths viz. 15 m and 20 m during the present study. It has been observed that at a depth of 20 m and 15 m bridle length, it has been found that there was a less catch when compared to that of 20 m bridle length. Whereas, for 20 m bridle length at the same depth, the fuel consumption was more in case of 15 m bridle length compared to that of 20 m bridle length. Similarly, at a depth of 25 m for the 15 m bridle length was found to be less catch when compared to 20 m bridle length to the same depth. As far as, fuel consumptions are concerned 20 m bridle length was found to be less fuel consumption when compared to that of 15 m bridle length. However, in the present study for the depth of 25 m and 20 m bridle length was found more suitable, when compared to the depth of 20 m, for both 15 m and 20 m bridle length. Therefore, it has been decided to adopt 20 m bridle length as a standardized bridle length for the trawl net to be operated during the operations of square mesh codend trawl net. | |
