The knowledge of the biological aspects and feeding activity of fish is required to manage the lack of data on fisheries. In this study, a total of 200 Plotosus canius were caught and examined to obtain information on their biological aspects, length-weight relationship, and feeding activity. The fish were captured using a gill net and traditional fishing trap called Bubu. Subsequently, all samples were examined for total body weight, total length, condition factor, gonad maturity, and feeding activity. The results showed that the specimens captured were 156 males and 44 females weighing between 95-280 gr and 117-214 gr with the length of 26-39 cm and 28-36.3 cm, respectively. The length-weight relationship showed a negative allometric growth pattern. The mean condition factors of males and females were 1.1048 and 1.0102, respectively. At the same time, the maturity level of gonads was at I and II. Moreover, it was discovered that most organisms in the digestive tract were shrimp, worms, small fish, and crabs, while the highest index of preponderance was in shrimp with 42%. In conclusion, this study showed the new information about length-weight, biological condition, and feeding habits of Plotosus canius, which can be inventoried to strengthen data on sustainable fisheries management.

Leaders bear heavy responsibilities and play a significant role in management, and thus they should possess wisdom and skills in making innovations for the success of their work. This study aimed to investigate the following issues: the types of leadership applied by the head of Dayah Raudhatul Qur'an, the leadership role of the head of Dayah in the development of students' behavior and the constraints faced by the leadership in the formation of morality students in Dayah Raudhatul Qur'an. The study employed a qualitative research design. Data were collected through observation, interviews, and documentation. The results of the study showed that the types of leadership applied by the head of Dayah tended to follow the democratic, deliberative, and charismatic leadership. The role of the head of Dayah in terms of shaping the students' behavior included establishing the regular Quran recitation, tausiah (giving advice), discipline, and dzikr (remembering Allah) after daily prayers. Further, the constraints faced by the leader in the formation of santri morality in Dayah Raudhatul Qur'an that is the influence from the outside because the majority of santri in Dayah Raudhatul Qur'an is a student from various universities and students are also busy by the tasks on campus so as not can focus on just one activity. Keywords: leadership role; head of dayah; developing students' behavior A.
