Ontogenetic of fish is a term used to study the development of the behavior of an individual throughout its life (life-span) from hatched to death. The mangrove ecosystem is a potential habitat for fish, especially the juvenile stage. Juvenile found in this habitat is an important economically fish. In various types of fish, the phenomenon of increasing the size of the fish body followed by changes in the types of food causing ontogenetic habitat of fish. It is evident in yellow snapper Lutjanus argentiventris. The juveniles live in mangrove habitat to approximately 100 mm or 300 days old, after which the fish move to deeper surrounding habitat. Mangrove forest that has a high complexity is to serve as an adaptation of fish to avoid predators and foraging. Several different habitats, both the mangrove ecosystem and other ecosystems provide different foods according to the needs at each phase-change of fish life. Animals that undergo ontogenetic habitat drift has management consequences that are more sensitive than animals inhabiting on single habitat. Hence, particularly habitat conservation resource management is needed. Not only conservation of the habitat, but also other habitats related to the migration of fish.

Giant clam population has been decreased in a few years. Resource management requires information from various aspects, such as ecological, population, and other aspects. This study was aimed at assessing the genetic profile of Tridacna giant clam in Wakatobi National Park waters using Cytochrome oxidase subunit I (COI) genetic marker. Sample collection was conducted around the three main islands, i.e., Wangi-wangi, Kaledupa, and Tomia. Genetic analysis using COI gene may contribute in identifying giant clams up to the species level and showed the relationship among species. The research found 41 specific nucleotide sites for the clams. T. crocea, T. squamosa and T. maxima had 2, 15 and 24 sites, respectively. COI gene as a biological marker was able to separate groups of giant clam by species. Nucleotide variation of T. crocea from Wakatobi was the highest among other locations, so it could be used as a genetic source for translocation and domestication. Keywords: cytochrome oxidase subunit I, specific nucleotide, Tridacna, Wakatobi National Park

The factors causing the degradation of mangroves in the Passare Apua village are low income, education, and community skills. Information from the Passare Apua Village Government revealed that 25% of the population did not have a job, so they were classified as non-productive people with minimal educational backgrounds and skills. The solution to the problems are to increase supervision, education, skills and income of local communities, for example by providing training programs on product processing made from local resources. One of the local resources that the people of Passare Apua Village have not utilized is the mangrove fruit which is still often found in the area. Mangrove fruit has been known as a resource that can be processed into food, such as mangrove sticks. This activity aims to train the community to produce processed mangrove products in the form of mangrove sticks with a high nutritional and economic value which the community can later make as an additional source of income. The method of implementing this activity consisted of two stages: counseling/delivery of materials and demonstrations and practices of processing mangrove fruit into mangrove sticks. The results of this activity indicated that the target audience had been able to process mangrove fruit into mangrove stick snacks and was interested in developing this mangrove stick as one of the new products to be marketed. --- Faktor-faktor penyebab degradasi mangrove di Desa Passare Apua adalah rendahnya pendapatan, pendidikan dan keterampilan masyarakat. Informasi yang didapatkan dari Pemerintah Desa Passare Apua diketahui 25% penduduk belum memiliki pekerjaan sehingga tergolong masyarakat non-produktif dengan latar belakang pendidikan dan keterampilan yang sangat terbatas. Solusi terhadap permasalahan tersebut adalah meningkatkan pengawasan, pendidikan, keterampilan dan pendapatan masyarakat setempat, misalnya dengan memberikan program pelatihan pengolahan produk berbahan baku sumberdaya lokal. Salah satu sumberdaya lokal yang belum dimanfatkan oleh masyarakat Desa Passare Apua adalah buah mangrove yang masih sering dijumpai di kawasan tersebut. Buah mangrove telah dikenal sebagai salah satu sumberdaya yang dapat diolah menjadi bahan pangan, seperti stik mangrove. Kegiatan ini bertujuan untuk melatih masyarakat menghasilkan produk olahan mangrove berupa stik mangrove yang bernilai gizi dan ekonomis tinggi yang nantinya dapat diproduksi oleh masyarakat sebagai sumber pendapatan tambahan. Metode pelaksanaan kegiatan ini terdiri dari dua tahap, yaitu penyuluhan/penyampaian materi dan demonstrasi serta praktek pengolahan buah mangrove menjadi stik mangrove. Hasil kegiatan ini menunjukkan bahwa Khalayak sasaran telah mampu mengolah buah mangrove menjadi cemilan stik mangrove dan berminat untuk mengembangkan stik mangrove ini sebagai salah satu produk baru yang akan dipasarkan.

One of the important capture fisheries commodities in Southeast Sulawesi, especially small-scale fisheries, is blue swimming crab (Portunus pelagicus) using traps. The catching is said to be successful if it gets the maximum profit for the business actor. The use of different types of bait in trap results in different catches. The purpose of this study was to analyze the financial aspects which include costs, income, profits, and the level of financial feasibility of catching crabs using different baits, namely peperek fish and anchovies. The method used in this study is a survey method, namely by reviewing, observing and collecting information data directly in the field. The results of the study indicated that the variable costs incurred annually have a greater amount than the fixed costs. The biggest revenue from the crab catching business was by using peperek fish bait, with the profits being able to cover the costs incurred. Crab fishing business using peperek fish is said to be feasible and profitable as seen from the value of NPV, IRR, and B/C Ratio with the return on capital in the category of medium return on capital. Meanwhile, by using anchovy bait, there is a loss, where the revenue obtained cannot cover the costs incurred.

Meretrix meretrix is a degraded resource in Kendari Bay waters, but its reproductive pattern is not fully known.. This study aims to determine the level of gonad maturity, gonadal maturity index, fecundity and the size of the first gonad maturity of M. meretrix at the Kambu River estuary, Kendari Bay, Southeast Sulawesi. This research was carried out at the Kambu River estuary for 6 months from August 2021-January 2022. These clams were taken randomly representing all size classes as many as 300 birds during the study. M. meretrix were observed for gonad color and gonad development microscopically, then the length and weight of the gonads were measured using a caliper and analytical balance with an accuracy of 0.5 mm and 0.0001g, respectively. The results showed that the development of male and female gonads was relatively simultaneous, which was dominated by mature gonads (III-IV) in each month of observation. TKG I-V was found in every month of observation. The gonad maturity index of males and females were 4.92-6.00 and 5.53-6.32, respectively. The fecundity of M. meretrix ranged from 4882-85677 grains. The first mature size of the gonads of male and female M. meretrix is 20 mm.

ABSTRAK Telah dilakukan penelitian tentang peranan tanaman sebagai biofilter untuk menjaga kualitas air media. Penelitian ini dilakukan dengan beberapa rangkaian kerja yang dimulai pada bulan Juni - Agustus 2022 di UPT Laboratorium Terpadu Unkhair Kota Ternate. Penelitian ini dirancang dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri 3 perlakuan dan 3 ulangan selama 60 hari. Pengukuran dilakukan terhadap suhu, salinitas, DO dan pH, amoniak, nitrat dan nitrit pada setiap minggu. Estimasi dilakukan terhadap efektifitas biofilter tanaman terhadap ammonia (N) dan fosfor (P) pada setiap perlakuan, pertumbuhan mutlak dan sintasan (SR) udang galah dan dianalisis menggunakan ANOVA dengan uji F pada taraf kepercayaan 95%. Uji Fisher (LSD) dilakukan apabila perlakuan berpengaruh nyata terhadap peubah yang diukur (P0.05). Hasil analisis memperlihatkan bahwa ketiga perlakuan tanaman tidak berbeda dalam menyerap N dari limbah budidaya udang galah. Sedangkan untuk penyerapan P dari ketiga perlakuan, jenis pakcoy menyerap paling efektif (0.725 mgL-1) dibandingkan dengan tanaman seledrei (0.540mgL-1) dan selada (0.186 mgL-1) (P0,05). Selain itu pula, konsentrasi ammonia selama penelitian cenderung menurun. Pertumbuhan mutlak dan laju pertumbuhan spesifik pada ketiga perlakuan tidak signifikan berpengaruh (P0,05), sedangkan sintasannya signifikan berpengaruh (P0,05). Meskipun demikian, ketiga tanaman dapat digunakan sebagai biofilter dalam system akuaponik.Kata kunci: Biofilter, tanaman, akuaponik, limbah, udang galahABSTRACTIt has been studied how plants can act as biofilters to preserve the standard of media water. The UPT Unkhair Integrated Laboratory in Ternate City will be the site of this research, with work series beginning in June 2022 and lasting through August 2022. Three treatments and three replications were used in this study's completely randomized design (CRD), which lasted for 60 days. Temperature, salinity, DO and pH, ammonia, nitrate, and nitrite were all measured on a weekly basis. ANOVA with the F test and a 95% confidence level were used to estimate the efficiency of the plant biofilter against ammonia (N) and phosphorus (P) in each treatment, absolute growth, and survival (SR) of gigantic prawns. When the treatment had a significant impact on the measured variables (P0.05), Fisher's test (LSD) was applied. The analysis's findings demonstrated that N absorption from the giant prawn industry's waste did not differ between the three plant treatments. Regarding the three treatments' P absorption, pakchoi (0.725 mgL-1) absorbed P more efficiently than celery (0.540 mgL-1) and lettuce (0.186 mgL-1) (P0.05). Additionally, there was a tendency for the study's ammonia concentration to decline. Survival had a significant influence (P0.05), although the absolute growth and specific growth rates of the three treatments did not (P0.05). However, all three plants can be utilized in aquaponic systems as biofilters.Keyword: Biofilter, plants, aquaponics, waste, giant prawns
