Unfortunately, the data on small-scale and traditional fisheries is still lacking. It makes it challenging to make fishing policies and regulations. Survey activities and experimental fishing were conducted to determine and analyze the composition of the main catch, bycatch and discarded by the local fisher's bottom traps in Sibolga, North Sumatra, Indonesia. Five units of the trap with a size of 150 cm x 100 cm x 50 cm (length x width x height) were used to collect fish data. These five trap units operated in the fishing ground, where local fishers usually operate their fishing gear. The fishing operation carried out within 1 mile of the coastline with water depths ranging from 7-10 meters. The duration of trap setting around 5-7 days for each fishing operation. A motorboat operated with a weight of 5.8 GT. The results showed that the total bottom trap catch consisted of 329 individuals with a total weight of 151.4 kg and 12 demersal fish species. The main catch was 148 individuals (88.9 kg), or 44.7% of the total catch during the experiment i.e. Chepalapholis urodeta, Ephinephelus areolatus, Epinephelus chlorostigma, Plectropomus leopardus, Ephinepelus coioides, Lates calcarifer, Lutjanus malabaricus, and Lutjanus erytropterus. The bycatch was 151 individuals (57.1 kg) or 46.1% i.e. Lethrinus obsoletus, Lutjanus ehrenbergii, Acanthurus auranticavus, Platax teira, Nemipterus japonicus, Scarus rivulatus, Lutjanus johnii, Siganus canaliculatus, Caesio cuning, and Taeniura lymma.While the discarded catch amounted to 30 individuals (5.4 kg) or 9.2% i.e. Naso brevirostris, Diodon holocanthus, and Diadema setosum. The bycatch utilization obtained by fishers was 83.4%, and the unutilized was 16.6%.

This researh used survey and random sampling methods, i.e taking research samples (tilapia, broom fish, and giant prawns) at 3 (three) observation stations, including Station 1 Amplas, Station 2 Denai, and Station 3 Percut. Heavy metal content (Pb and Cd) and microbiological quality (E.coli and Salmonella, sp) were analysed. Data analysis was done by inference and calculated using Microsoft office Excel (Microsoft Inc., USA) descriptively. The results showed that all samples in each observation did not meet the quality standard value requirements according to SNI 2729:2013 and SNI 2705:2014. The average heavy metal content of Lead (Pb) was 0,3 mg/kg in tilapia and broom fish, and 0,5 mg/kg in giant prawns. The content of heavy metal Cadmium (Cd), were 0,1 mg/kg in tilapia and broom fish, and 0,5 mg/kg in giant prawns. All samples also showed positive in containing E.coli and Salmonella, sp. The value of Bioaccumulation Factor (BAF) of heavy metals (Pb and Cd) in all samples was 1, meaning that the sample's ability to accumulate heavy metals (Pb and Cd) was high.

The price of feed with high protein content which is relatively expensive is a big problem in the catfish farming process. On the one hand, there is shrimp head waste which is a source of protein with a protein content of 42.16% - 49.8% which has not been utilized and is disposed of as waste. Through this research, the shrimp head waste was carried out by an enzyme hydrolysis process to produce shrimp soluble extract (SSE) using a protease enzyme. The SSE that has been produced is then given to catfish aged 14 days to support the addition of protein sources for the growth of catfish. During the 1 month trial, there was a significant difference in results in the treatment catfish with the addition of 2% SSE compared to the control catfish. The addition of SSE gave a very good effect on the weight of catfish which was randomly distributed in a tank containing 50 catfish with an average initial weight of 0.6-0.8 grams. The provision of SSE was carried out simultaneously with the provision of standard fish feed, namely 3 times a day. The increase in catfish weight after being treated was about 2 grams/week. This indicates that SSE can increase the growth of catfish and can be used as an alternative supplement in the future because in addition to reducing the level of pollution due to catfish waste, it can also be a new discovery in the field of fisheries.","PeriodicalId":30450,"journal":{"name":"Depik Jurnal","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74154830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
