AbstractMystus nigriceps commonly inhabit the Tarai River that is polluted by tofu industrial liquid waste. Low water quality may affects fish growth and that is reflected in the growth ring pattern of the otolith. A research aims to understand the pattern of otolith growth rings in the M. nigriceps was conducted in April to May 2019. The fish was captured using a cast net, and a scoop net. There were 90 fishes captured (31 males and 59 females). The otolith were removed and shaved. The dark growth ring pattern was investigated using a binocular microscope. Results shown that the standard length of the fish ranged from 75.11 to 150.44 mm and their body weight was 3.27 to 44.82 g. The otolith length was 1.375 to 2.625 mm and its width was ranged from 0.85 to 1.375 mm. Among the fish captured, 82 of them having 1-3 dark rings, indicate that the in certain period the growth of fish in the Tarai River is hampered. The distance between the nucleus and the first dark ring was 0.25 to 0.625 mm and there was no special pattern in the formation of the first dark ring. This fact indicate that the first dark rings are formed individually and it is not formed by periodic events in fish life. The water quality parameter value are as follows, temperature 27-280C; pH 6; DO 3.2-3.5 mg/L; and CO2 23.09-24.98 mg/L) and it is able to support the life of fish.

Trawl has the size a mesh size a small size pockets of the cod end. This allows the trawl fishing gear to potentially be a fishing gear that is not selective about the size of the fish and the species that are targeted for its catch. If this fishing gear is left, its existence will eventually have a negative impact on the sustainability of fish resources, especially in coastal waters. The purpose of this study is to calculate the composition and proportion of main catches, bycatch and discarded catches. It is expected that knowing the composition and proportion of the main, by-product and discarded catches can provide an overview of the pressure on stocks and sustainability of fisheries resources in the waters where trawl is operated. The method used in this study is a survey method. A series of survey activities were carried out directly in the field to identify and count the types of species caught by trawlers. Based on the percentage of main catch, by-catch and discard per type, it Matuta planipes are the dominant species caught by trawlers (23.65%). The main catch Parapenaeus longirostris 15.92%. In addition, the main catch caught were Parapenaeopsis sculptilis (9.787%), Penaeus merguiensis (0.646%), Metapenaeus brevicornis (10.118%), Penaeus indicus (0.029%) and Squilla mantis (0.153%). Percentage of bycatch reaches 2.245% of 10 species caught and discarded catches reach 61.103% of 25 species caught.

This research was conducted from July to October 2021 in Bengkalis Regency. This research is focused on evaluating in detail the condition of the ultimate fisheries from the ecological, social, economic, and institutional aspects as well as scientific information for follow-up planning and implementation of the best fisheries management in the waters of the Bengkalis Strait. The research method used during the study was a survey method. Types and sources of data used in this study are primary data and secondary data. The number of key respondents used in this study were 30 people. Sustainable fisheries management is seen from five dimensions, namely the ecological dimension, the economic dimension, the social dimension, the technological dimension and the institutional dimension. The scores for each attribute were analyzed using the Rapfish technique and will be passed through several analyzes such as multi-dimensional scaling (MDS), leverage analysis (JackKnife), and Monte Carlo analysis. Based on the results of the study the results of the catch of the terubuk fish during the period June-September amounted to 160 fish. From this amount, it showed that the percentage of male fish caught was much more dominant, namely 110 fish (69%) than 50 female fish (31%). The results of the analysis of each dimension show that the ecological index (59.92%) is included in the moderately sustainable category, the economic dimension (52.94%) is included in the moderately sustainable category, the social dimension (50.54%) is included in the moderately sustainable category, the social dimension (50.54%) is included in the moderately sustainable category. Institutional (49.91%) is included in the sustainable category and the technological dimension (70.25%) indicates the category is quite sustainable. Thus, the design of the terubuk fish management in Bengkalis waters can use the dimensions of the attributes that are classified as quite sustainable, to support or improve the institutional dimensions in order to support the management of terubuk fish
