Mantis shrimp is one of the marine organisms that has a very abundant diversity of species. The similarity of morphology of this group make it difficult to identify morphologically. Therefore, identification was carried out using a DNA barcoding approach. The purpose of this study was to identify the mantis shrimp species from Manokwari waters using molecular techniques. The CO1 gene fragments were amplified by using LCO and HCO primers. The DNA sequences obtained were analyzed for homology, phylogeny, and genetic distance using MEGA X software. A total of 537 base pairs of CO1 gene fragments of mantis shrimp from Manokwari were obtained. The results of the homology analysis on GenBank, show the highest similarity of 91.18% with sequences from the genus Gonodactylus. Analysis of phylogenetic tree and genetic distance showed the same results and supported each other with homology analysis on GenBank data.

:Maluku as an archipelago province with the highest potential for fishery in Indonesia, where people occupy more than 75 percent of coastal areas and small islands (DKP Maluku Province, 2017) which still live below the poverty line. The government has made various efforts to alleviate poverty of coastal communities by providing aid package through policy to provide capture fishery assistance package but the results obtained have not been maximized. In addition, there has not been an in-depth evaluation of the impact of providing aid package to fisherman in Ambon City.This study aims to analyze the characteristics of recipients of aid packages and analyze the impact of policies on fishery assistance packages. This study was conducted in May - June 2019. The data of this study are consisted of primary and secondary data. Sampling was done by total sampling, which amounted to 44 respondents and method used is Descriptive Statistic and Editing, Scoring, Tabulating, Processing and Cleaning. Based on the results of the study there were 12 characteristics of respondents which are divided into 4 social characteristics and 8 economics that receive of assistance package in Ambon City and then the mechanism of giving and managing fishery assistance package in the form of tonda fishing rod (1.5 GT) was not good.

Parit Sembin, Parit Derabak, dan Parit Cabang Kiri digunakan untuk irigasi pertanian dan aktivitas domestik. Saluran air juga merupakan media hidup bagi beberapa jenis ikan. Keberadaan jenis ikan di Parit Sembin, Parit Derabak, dan Parit Cabang Kiri belum pernah dilakukan. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis ikan dan struktur komunitas ikan di ketiga paerit tersebut. Penelitian ini dilakukan pada bulan November-Desember 2019. Jenis ikan yang ditemukan adalah Rasbora sp, Trichopsis sp, Barbodes sp, trichogaster leeri, Osteacillus vittatus, Demogenys sp, Kryptoterus sp, Anabas testudineus, Trichogaster pectoral, Channa striata sebanyak 1.617 individu. Nilai Indeks Keanekaragaman jenis ikan di Parit Sembin, Derabak, dan Cabang Kiri tergolong rendah. Nilai Indeks Keseragaman di Parit Sembin dan Derabak tergolong sedang dan Nilai Indeks Keseragaman di Parit Cabang Kiri tergolong rendah. Nilai Indeks Dominansi Parit Sembin dan Derabak tergolong rendah dan Nilai Indeks Dominansi Parit Cabang Kiri tergolong tinggi.

Sungai Buaya merupakan salah satu sungai di Pulau Bunyu yang di sekitarnya terdapat aktivitas pemukiman, pertanian, dan perikanan (penampungan dan pengolahan hasil tangkapan ikan) serta sebagai tempat sandaran kapal nelayan dan transportasi laut. Aktivitas tersebut akan menghasilkan bahan pencemar yang berbeda dan masuk ke sungai baik secara langsung maupun tidak langsung. Bahan pencemar yang masuk ke sungai akan mempengaruhi kualitas air dan menyebabkan terjadinya penurunan kualitas air apabila terjadi secara terus menerus tanpa kontrol terhadap sumber bahan pencemar. Salah organisme yang terpengaruh oleh penurunan kualitas air adalah makrozoobentos. Penelitian ini bertujuan untuk mengetahui keanekaragaman makrozobentos di Sungai Buaya. Penelitian dilaksanakan pada bulan Agustus-Oktober 2013. Pengambilan sampel sedimen dan makrozoobentos menggunakan Eckman Grab. Sampel sedimen diambil sebanyak ± 500 gram dan dimasukan ke dalam kantong plastik. Sedangkan sampel makrozoobentos dipisahkan dari sedimen menggunakan saringan ukuran mata saring 0,5 mm. Sampel yang tersaring diawetkan dengan formalin 5%. Analisis struktur komunitas makrozoobentos dilakukan dengan menentukan komposisi (kepadatan), keanekaragaman (H’), keseragaman (E), dominansi (C). Struktur komunitas makrozoobentos memperlihatkan nilai indeks keanekaragaman yang rendah. Nilai indeks keseragaman tergolong tinggi dan indeks dominansi tergolong rendah. Tidak ada dominansi spesies di perairan Sungai Buaya. Makrozoobentos yang ditemukan selama penelitian terdiri dari 4 kelas yaitu Bivalva (1 jenis), Gastropoda (13 jenis), Crustacea  (1 jenis), dan Polichaeta (2 jenis).

Giant prawns are one of the leading commodities of the people of Sambas Regency. From a socio-cultural perspective, catching giant prawns has been going on for a long time and until now it has become a habit and a hobby which has even become an international event that is packaged in the form of a fishing competition. Indirectly, the giant prawn business expands and plays a role in moving other sectors, such as the tourism sector, either in the form of tours or culinary. Catching giant prawns in Sambas Regency is already intensive because it only depends on the fishing sub-sector and lasts all year round. This study aims to predict the current status of giant prawn resources in various dimensions in order to formulate strategic policies in sustainable management. Based on the results of the RAPFISH analysis on each dimension of sustainability, it can be concluded that the sustainability status of giant prawn (Macrobrachium rosenbergii) resource management in Sambas Regency, West Kalimantan, has a sustainability index value of 45.34. Sustainability status is in less sustainable condition or poor management status. The highest sustainability index value is found on the social dimension and the lowest on the institutional dimension. Of the five dimensions of sustainability, the social and ecological dimensions show results that are still supportive for the sustainability of the giant prawn (Macrobrachium rosenbergii) resource management in Sambas Regency, West Kalimantan. And the other three dimensions must be given special attention because the sustainability dimension has an impact on the sustainability of management with a less sustainable status or poor management status. Especially on the institutional dimension, it should be an evaluation for local governments. Based on the facts on the ground, there is no real formal institution in catching giant prawns, unlike fishing groups or other fish farming groups. That's why it is believed that in planning the development of fishing groups or fishing for giant prawns, it is currently impossible to do. So that in the future a formal regulation from the local government is needed regarding the business actors of catching giant prawns in Sambas Regency.
