Penelitian respons mimi terhadap cahaya light emitting diode merah dengan intensitas yang berbeda telah dilakukan pada skala laboratorium. Penelitian ini bertujuan untuk menentukan pola dan laju respons mimi terhadap lampu LED merah dengan intensitas yang berbeda serta menentukan tingkat intensitas LED merah yang tepat untuk mitigasi bycatch mimi. Metode penelitian yang digunakan adalah eksperimen skala laboratorium dengan tiga variabel intensitas cahaya LED merah, yaitu rendah (3,68 × 10-6 W/cm2), intensitas sedang (5,47 × 10-6 W/cm2), dan intensitas tinggi (1,05 × 10-5 W/cm2). Pengujian dilakukan untuk mengamati pola dan laju respons mimi terhadap tiga intensitas cahaya lampu LED merah. Spesies mimi yang dijadikan objek penelitian adalah Tachypleus gigas. Jumlah mimi yang digunakan sebanyak 20 ekor dengan panjang total 30-38 cm. Analisis data yang digunakan adalah metode deskriptif komparatif. Hasil penelitian menunjukkan terdapat respons mimi menjauhi cahaya terbanyak pada LED merah intensitas rendah sebanyak 60%, sedangkan intensitas sedang dan tinggi sebanyak 35% dan 34%. Adapun waktu respons mimi yang tersingkat terdapat pada intensitas cahaya LED rendah selama 32,05 detik dan waktu respons terpanjang terdapat pada intensitas tinggi selama 59,06 detik. Berdasarkan respons penghindaran tersebut, lampu LED dengan intensitas 3,68 × 10-6 W/cm2 dapat digunakan sebagai alternatif dalam mitigasi bycatch mimi pada perikanan jaring insang dasar. Research on the response of horsehoe crab toward red light emitting diode lamps with different intensities were carried out on laboratory scale. The purpose of this study were to analyze the pattern and response rate of horseshoe crab against red LEDs with different intensities and determine the intensity of red LED light that is suitable for mitigation bycatch of horseshoe crab. The research method used was experimental laboratory with three viriables, namely low intensity (3,68 × 10-6 W/cm2), moderate intensity (5,47 × 10-6 W/cm2), and high intensity (1,05 × 10-5 W/cm2). The experiment was carried out by observing the pattern and the response rate for the red LED lights. The type of spesies used in research is Tachypleus gigas. The number of horseshoe crabs used was 20 with a total lenght of 30-38 cm. Data analysis used was deskriptive comparative method. The result showed that the intensity of the most avoided by horseshoe crab was a low intensity of 60%, while the moderate and high intensity were 35% and 34% respectively. The shortest horseshoe crab response time is at low intensity for 32,05 seconds and the longest response time is at high intensity for 59,06 seconds. LED light with an intensity of 3,68 × 10-6 W/cm2 provide an avoidance response to horseshoe crab. Based on the avoidance response, LED lights with an intensity of 3,68 × 10-6 W/cm2 can be used as an alternative in mitigation bycatch of horseshoe crab for bottom gillnets fisheries.

The need for fishery products that are healthy, safe, legal, sustainable, and democratic from time to time continues to increase. This makes the export destination country require a certificate issued by an institution. One of the standards used by such countries is the MSC ecolabel. MSC ecolabel is an endorsement of a product that meets the criteria of environmental sustainability procedures and hasbeen well managed. Ecolabel identifies fisheries governance properly based on established criteria, relating to the utilization of fishery resources and marine ecosystems. Therefore, it is necessary to conduct an assessment related to the application of MSC ecolabels in the Sibolga tuna processing industry. The purpose of this study is to analyze the level of gap (gap analysis) and the suitability of the application of the MSC ecolabel and examine various inhibiting factors. This research was conducted using survey methods and Focus Group Discussion (FGD) with industry and Sibolga Archipelago Fishing Port. The analysis used was qualitative descriptive analysis, gap analysis, and conformity level analysis. The results showed that the level of conformity in the MSC CoC of 5 (five) criteria, only 1 criterion was in accordance with the standard, while the other four had not, with the level of conformity being 63.75%, 83.25%, 66.75, and 57.25%. The results of the assessment of the inhibiting factors were obtained from fishermen, processing industries, and government support. Keywords: MSC CoC, Sibolga, traceability, yellow fin tuna.

Large pelagic fish live on the water surface in groups. Skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), mackerel tuna (Euthynnus affinis), mackerel (Scomberomous guttatus) are species of fishes that mainly catches by fishermen using purse seines. This study aims to determine the length and weight of large pelagic fish in the water of Idi Rayeuk and best the fishing season. This research was conducted in one month. Fish samples were collected from fishermen that used purse seine and landed their catches at the Idi Rayeuk Fishing Port, East Aceh. Additionally, the data was derived from the fishing port time-series during 2015 to 2019. The result showed that the yellowfin tuna (Thunnus albacares) has a length between 37 - 58 cm with a weight of 1.0 - 3.2 kg, skipjack tuna (Katsuwonus pelamis) 32 - 58 cm in length and weight 0.5 - 3.0 kg, mackerel tuna has 33 - 54 cm of length with a weight of 0.6 - 2.5 kg, and mackerel has 44 - 66 cm of length and weighing 0.7 - 1.7 kg.

Pulau Banyak and Pulau Banyak Barat Districts. play an active role in advancing capture fisheries production, this can be seen from the larger number and size of vessels operated so as to produce larger capture fisheries production. To land and sell their catch, many private entrepreneurs do it in their private holdings, not in government-owned fishing ports. This Tangkahan generally has relatively little land and facilities, but the activities and production are relatively large. This study aims to analyze the catch landed on the Tangkahans of Banyak Island, Aceh Singkil and make a map of the location of the Tangkahans in Pulau Banyak, Aceh Singkil. The method used is in 2 stages, the first stage is conducting a field survey using interview questionnaires, and the second stage is collecting field data (coordinate points of Tangkahan, types of catches and aerial photos of Tangkahan Island many). The location of the research is on Banyak Island, Aceh Singkil. The results of the study showed that there were 12 Tangkahans in Pulawa many, of which 8 units were in Baguk Village and 4 units were in Balai Desai. The catches that landed consisted of Squid, Dencis Fish, Tuna, Coral Anchovy and others. This is because the fishing gear used by Pulau Banyak fishermen is dominated by Bagan.

The nutritional content of fish is very high in protein and omega 3 fatty acids, but there is still little interest in eating fish among children. The government is trying to prevent stunting by launching the GEMARIKAN (Gemar Makan Ikan/Fond of eating fish) program to fulfill nutrition sourced from fish. Fish are generally less popular because their shape makes them uninteresting and boring, so interest in eating fish decreases. Housewives are encouraged to play a role in fulfilling children's nutrition through fish intake using various techniques, one of which is processing fish into a variety fish-based food. Alternative fish-based food is made to attract families to consume it by empowering groups of housewives and young women. This training aimed to educate about alternative fish-based food and recommend business opportunities to support additional family income. Training activities were carried out through mentoring and counseling for 20 housewives and young women from Gampong Blang Padang, by forming small groups and providing education regarding techniques for processing fish into dimsum products, fish sticks and fish nuggets. The results of the training showed that housewives and young women were able to make more varied fish preparations. Apart from that, participants received counseling about the benefits of fish for health, not only as an ingredient in making various types of processed fish food that have nutritional and economic value.
