Abstract

Pemanfaatan sumberdaya perikanan Indonesia diberbagai wilayah yang tersebar di negeri ini, masih memiliki kekurangan yang signifikan. Ini dapat dilihat pada beberapa wilayah perairan yang masih terbuka peluang besar untuk pengembangan pemanfaatannya, dikarenakan belum optimalnya kinerja pemerintah untuk memberikan informasi yang dapat dijadikan sebagai acuan nelayan ketika melakukan aktifitas penangkapan ikan, terutama informasi tentang daerah penangkapan ikan (fishing ground). Tujuan dari penelitian ini adalah untuk memetakan daerah penangkapan ikan berdasarkan sebaran konsentrasi klorofil-a, salinitas perairan dan suhu permukaan laut untuk pendugaan daerah penangkapan ikan cakalang di perairan Kota Ternate, dengan memanfaatkan teknologi penginderaan jauh. Hasil penelitian menunjukkan bahwa, daerah yang sesuai untuk penangkapan ikan cakalang adalah daerah yang memiliki kandungan klorofil-a, salinitas dan suhu perairan yang sesuai dengan faktor oseanografi kehidupan ikan cakalang. Berdasarkan hasil penelitian, diketahui bahwa daerah penangkapan ikan cakalang di perairan Kota Ternate berada pada bagian barat Pulau Ternate dan Pulau Hiri, dengan posisi 1°14'58,94” LU – 127°46'36” BT sampai dengan 1°37'37,4” LU – 126°19'18,6” BT dan 0°35'82,5” LU – 127°81'10,43” BT sampai dengan 1°06'85” LS - 127°39'33,82” BT. Kata Kunci :  Daerah penangkapan ikan, klorofil-a, salinitas, suhu permukaan laut, penginderaan jauh

Abstract

The tuna fish (Thunnus spp.) is highly migratory and commercial tuna fishery. The fish tuna abudance supported ocea-nography and geography condition in North Mallucas Sea. The fishery targets catch increase on fish tuna provided a view of the need for assessment of phylogenetic tuna. The study was conducted to infer the phylogenetic in North Mollucas Sea. The research method was PCR-Sequensing. Moleculer analysis included extraction, Polymerase Chain Reaction (PCR), electrophoresis and DNA sequencing in control region mtDNA locus. Phylogenetic reconstructed with Neigbor joining with Kimura 2-parameter model using MEGA5. The result showed that four clade (bigeye, yellowfin, alalunga and skipjack). Genetic distance between bigeye with yellowfin was (0.084), bigeye with alalunga (0.163), ye-llowfin with alalunga (0.174), bigeye with skipjack (0.294), skipjack with alalunga (0.312) and yellowfin with skipjack (0.297). The overall result showed significant genetic different. That information explain about one populations species tuna. The tuna phylogeography unlimitedin geographic distributions. Abstrak Ikan tuna (Thunnus spp.) adalah ikan pelagis yang memiliki kemampuan ruaya dan nilai komersial. Kondisi oseanogra-fis dan letak geografis mendukung kelimpahan stok sumber daya ikan tuna di Perairan Maluku Utara. Aktifitas penang-kapan yang meningkat memberikan pandangan perlu adanya pengkajian filogenetik ikan tuna. Penelitian ini bertujuan untuk memperoleh informasi filogenetik ikan tuna di perairan Maluku Utara. Metode yang digunakan adalah metode PCR-Sekuensing pada lokus mtDNA control region. Analisis molekuler meliputi ekstraksi, Polymerase Chain Reaction (PCR), elektroforesis dan sekuensing DNA. Rekonstruksi pohon filogenetik dengan metode Neighbor joining dengan model evolusi Kimura 2-parameter dilakukan menggunakan aplikasi MEGA5. Hasil penelitian menemukan empat clade spesies ikan tuna yang berbeda (tuna mata besar, sirip kuning, alalunga, dan cakalang). Jarak genetik tuna mata besar (Thunnus obesus) dengan sirip kuning (Thunnus albacares) adalah 0,084; tuna mata besar dengan tuna alalunga (Thunnus albacore) adalah 0,163; tuna sirip kuning dengan tuna alalunga sebesar 0,174; tuna mata besar dengan caka-lang (Katsuwonus pelamis) adalah 0,294; cakalang dengan tuna alalunga adalah 0,312; dan tuna sirip kuning dengan cakalang adalah 0,297. Semua hasil menunjukkan perbedaan genetik signifikan. Namun dapat dijelaskan bahwa spesies tuna berasal dari satu keturunan. Filogeografi tuna tidak memiliki batas distribusi yang nyata spesies.

Abstract

Pangasius sp is an introductory species that is widely distributed in freshwater regions in Indonesia since the 1990s and it was initiatively reared at the beginning of 2011 using a floating net cage in Lake Ngade, Ternate. Even though it has benefited economically, there is still a lack of information on its biological and ecological aspects. Growth and survival rate are two main factors that should be known to develop Pangasius aquaculture. The study aims to understand the growth and survival rate of Pangasius by mixing different fish meals into dietary. 120 Pangasius fingerlings were placed into 12 tanks. Diet was formulated using Pearson’s square method. Three different protein fish meal sources were mixed into feed formulation namely flying fish meal, Nile meal, and eel meal. Commercial feed was used as control. Filling Randomized Design (FRD) was applied with the experimental set-up of the treatments. The results show that feed stability in water ranges from 2'23" to 3'47" while feed durability ranges from 2'09" to 2'35". The survival rate of Pangasius is almost 100% except for treatment C. Growth rates vary among treatments which is the highest found in treatment A (16.42%) followed by treatment B (15.85%), D (15.57%), and C (7.00%) respectively. Nile fish meal is also significantly affected (P<0.05) by the Specific Growth Rate (SGR) of fish. Nutrition ingredients and water quality parameters are conducive to maintaining the fish's life. All in all, different fish meal sources in the formulated diet are significantly supporting Pangasius growth.

Abstract

The Standard of living for fishermen’s families can be achieved through economic creativity by developing and diversifying fishery products. Women in fishery families have an essential contribution and an important role in their households. However, the part is not only domestically but also publicly, such as in marketing the products, refinement of the fishing gears, and fishing activities, among others. The object of the Community Service is mentoring activities and imparting knowledge through the diversification of fishery processing product with the fisherwomen (fishermen's wives and fisherman's daughters who do not have regular activities) as the targeted people. The activity was carried out in July 2022 at the Jambula KUB, Ternate City, North Maluku Province. Initial activities conducted were observation and discussion related to the desire and interest of fisherwomen to utilize fishery products to have added value through the process of fish catches. Results: The outputs that will result from this community service activity are (1) diversification of fish food products (local name : mpek=mpek and fish meatballs); (2) transferring of business management knowledge on how to make financial report for fishermen's families and (3) introducing the use digital media for business and marketing purposes and (4) the ability of fisherwomen to obtain other income from the small-scale fishery that has an impact on the family welfare, (5) Fishermen's family life is more prosperous and (6) scientific publications through reliable journals.
