MORFOMETRI KERANG Anadara granosa di PERAIRAN SUKAL BANGKA BARAT
Indonesia memiliki potensi sumberdaya hayati yang sangat besar karena memiliki merupakan wilayah kepulauan yang memiliki luas laut sebesar 3.257.357 km² dan garis pantai sepanjang 95.181 km serta potensi sumberdaya lautan sebesar 10,2 juta ton/tahun. Organisme kerang adalah hasil perikanan yang melimpah di Indonesia sekaligus dapat dijadikan sumber protein hewani yang berguna bagi fungsi tubuh dan harganya yang murah sehingga dapat dijangkau oleh masyarakat. Kerang darah merupakan salah satu jenis kerang yang digemari masyarakat Indonesia. Kondisi perairan di daerah sukal diyakini oleh masyarakat sekitar sebagai tempat habitat yang baik terutama kerang darah. Aspek morfometri merupakan faktor yang sangat penting karena dengan morfometri dapat memahami pola pertumbuhan kerang yang terdiri dari pertumbuhan allometrik positif dan allometrik negatif. Tujuan penelitian ini adalah untuk menganalisis dan mengetahui karakteristik morfometri kerang darah di perairan desa Sukal. Pengambilan sampel kerang darah (Anadara granosa) dilakukan pada perairan Sukal Kabupaten Bangka Barat. Hasil penelitian pengukuran morfometri menunjukkan panjang cangkang kerang darah adalah 3-3,7 cm, berat total kerang darah 11-19 gram, berat daging kerang darah 2-5 gram, lebar cangkang 2,2-2,8 cm dan tinggi cangkang 2,1-2,5 cm. Hubungan antara panjang cangkang dengan berat total dan berat daging kerang darah adalah allometrik negatif yaitu pertambahan panjang lebih cepat/dominan dibandingkan pertambahan berat dengan masing-masing nilai konstanta b<3.

Terdapat 7 jenis ikan di Stasiun 1 (Sungai Kace), 4 jenis ikan di Stasiun 2 (Sungai Petaling, 5 Jenis ikan di Stasiun 3 (Sungai Kemuja) dan 1 Jenis ikan di Stasiun 4 (Sungai Zed). Struktur komunitas ikan di beberapa stasiun penelitian terdiri dari Indeks Keanekaragaman (H’) sebesar 0,731 untuk Sungai Desa Kace; 0,598 untuk Sungai Desa Petaling; 1,118 untuk Sungai Desa Kemuja; dan Sungai Desa Zed adalah 0. Hasil analisis komponen utama (PCA) diperoleh faktor kualitas perairan yang paling berpengaruh terhadap indeks keanekaragaman ikan adalah parameter DO (Oksigen Terlarut), parameter Nitrat (NO3) dan parameter Fosfat (PO4). Dimana paramater tersebut berpengaruh terhadap nutrisi/kesuburan perairan serta kandungan oksigen yang berpengaruh terhadap pertumbuhan dan perkembangan ikan.

Metode Penangkapan Udang Rebon (Acetes Sp.) dengan Alat Tangkap Sungkur sebagai Bahan Baku Pembuatan Terasi di Kecamatan Toboali Kabupaten Bangka Selatan
Sungkur is a traditional fishing gear used by Toboali fishermen to catch rebon shrimp. Rebon shrimp is the main raw material in making shrimp paste in Toboali District. This study aims to identify the construction of thrust fishing gear and find out how to operate the thrust fishing gear used in Toboali District, South Bangka Regency.The time and place of this research was carried out in November 2019 to December 2019 in Tanjung Ketapang Village and Rias Village, Toboali District, South Bangka Regency. Data taken from secondary data from various related agencies and primary data in the form of questionnaires were 74 respondents. The method of selecting respondents is done by the method of purposive sampling. Identification of the construction of bay fishing gear refers to the Food and Agriculture Organization (FAO) and according to the Republic of Indonesia Minister of Maritime Affairs and Fisheries Regulation No. 6 of 2010.The research methods used in the study are the questionnaire, interview, and observation methods. The analysis used is qualitative analysis. The results showed that the thrust fishing gear consisted of several parts, namely the stem, frame, legs, nets, bags, buoys, and weights. The operation of the thrust fishing gear is divided into several stages, namely the preparation of the fishing gear, to the location of the capture of the rebon shrimp, the operation of the fishing gear, and the collection of catches.

TINGKAT PREVALENSI CACING ENDOPARASIT IKAN TONGKOL (Euthynnus affinis) YANG DIDARATKAN DI PELABUHAN PERIKANAN NUSANTARA (PPN) SUNGAILIAT KABUPATEN BANGKA
The existence of parasitic worms in fish can diminish the value of the fish. This research aims to identify the type of parasitic worms that infect the little tuna (Euthynus affinis) with the prevalence rate, examine the intermediate host of the parasite and examine the most infected fish based on the total length. This research conducted in January 2020 at nusantara fishery harbor of Sungailiat Bangka Regency using the random sampling method. The results showed that the parasitic worms that infect the little tuna consist of species from Didymozoon lobatum that infect the gills with the often prevalence category which is 23.190%, Dinurus tornatus, Dinurus scombri, and Rhadinorhynchus Pristis that infects the stomach and intestine with prevalence respectively often with the amount of number 2.898%, 1.449% and 24.640% for occasionally category. There was no parasite found in the muscle of the fish and the abdominal cavity.The composition of the food consists of Synedra sp (4,547%), Nocticulla scintillans(0,395%), Coscinodiscus raidatus (0,110%), Melosira varians (2,384%) and shrimp larvae. The results showed that the largest food index of little tuna (Euthynnus affinis) is the shrimp larvae with the index of preponderance of 89.170% and suspected as the intermediate host of the parasite. The result indicated that there was no parasite in fish with a total length under 25 cm. Little tuna that infected by parasitic worms is dominated in the size with the range of 32 – 34,1cm with the most commonly parasitic worms found is the species from Rhadinorhynchus pristis.

POLA PERTUMBUHAN DAN FAKTOR KONDISI IKAN BAUNG (Mystus nemurus) DI SUNGAI UPANG DESA TANAH BAWAH KABUPATEN BANGKA
This study aims to analyze growth patterns, condition factors, sex ratio of Baung Fish (Mystus nemurus) and environmental parameters of Upang River, Tanah Bawah, Bangka Regency. The time and place of this research was carried out from December 2019 to February 2020 in the waters of the Upang River, Tanah Bawah Village. The sampling point was determined by purposive sampling method which was divided into 3 research stations. Baung fish sample data collection was carried out using gill nets with mesh sizes ¾ inch, 1 inch, 1 ½ inch, 1 ¼ inch, 1 ¾ inch, and 2 inch. The results of the growth parameters of Baung Fish (Mystus nemurus) are L∞ = 217.35 with a K value of 0.330 and t0 of -0.287. The relationship between length and weight obtained the growth pattern of male Baung Fish is negative allometric and female is allometric positive. The results of the analysis of the condition factor for male Baung fish were 0.678 and females were 1.798. Based on the results of the calculation of the sex ratio of Baung Fish, there were 37 males and 16 females with a ratio of 1: 1.31. The results of the analysis of temperature parameters ranged from 28-31 0C, pH ranged from 4-5, brightness ranged from 32.18-91.35%, depth ranged from 4.37-6.64 m, current velocity ranged from 0.04-0.08 m / s, dissolved oxygen (DO) ranging from 3.07-644 mg / L shows that it still meets the standards for the survival of the Baung Fish (Mystus nemurus) organisme.

Pengaruh Pemberian Pakan yang Berbeda Terhadap Pertumbuhan Tukik Penyu Sisik (Eretmochelys imbricata) Di Konservasi Penyu Aik Batu Banyak Desa Keciput Kabupaten Belitung
The existence of turtles have endangered, so that the efforts of preserve population is needed to through captive breeding efforts. In conservation efforts (breeding), selection of the right feed will be affect a good growth. The purpose of this study is to determine the effect of different feed and to know the percentage level of different feed efficiency on the growth of hatchlings. This research conducted for 8 weeks at Aik Batu Banyak of Conservation of Turtle Sea, Belitung Regency. The research method is experimental used a complete randomized design (CRD). The study conducted 4 treatments with 3 replications. The results of the study showed that feeding different from the growth of hawksbill sea turtles have no significant or significant differences. Hawksbill turtle hatchlings which fed a mixture of 75% anchovies + 25% tamban fish produce higher values ​​of carapace length and carapace width compared to other feeds. Meanwhile, anchovy feeding produces higher hatchlings than other feeds. The length and weight relationship is negative allometric. The highest percentage level of feed efficiency in fish pond food.
