Abstract

Mangroves are an important part of determining conservation areas as well as determining zoning within conservation areas. Therefore, information on the status and distribution of mangroves is essential in managing conservation areas. This study was conducted in Taman Pulau Kecil, Central Tapanuli District. The data was collected in June 2019. The sampling sites consisted 26 points (1-15 at the Mursala Island and its surroundings and 16-27 in the Tapian nauli Bay (maindland)). The study revealed 17 mangrove species from 9 families consisted of 14 true mangroves and 3 associated mangroves namely pandan (Pandanus tectorius), waru (Thespesia populnea), and ketapang (Terminalia catappa). Analysis of the importance of mangrove species in Taman Pulau Kecil, Central Tapanuli district showed that Rizophora, Xilocarpus, and Bruguiera have a large influence and role in the mangrove vegetation community. Mangroves in conservation area at Taman Pulau Kecil were in the good category. However, the condition and status of mangroves in Tapian Nauli Bay had better condition with the density of 3.120 ind/ha while in Mursala  Island and its surroundings with density of 2.356 ind/ha.Keywords: Mangrove, Marine Protected area, Mursala Island, Tapian Nauli BayABSTRAKMangrove merupakan salah satu ekosistem penting dalam penentuan kawasan konservasi serta dalam penentuan zonasi di dalam kawasan konservasi.

Abstract

High fish stock density causes a decrease in water quality due to increased organic waste in water media and this can be overcame using biofloc technology. The bacterial consortium in the biofloc system breaks the organic compound into nutrients for phytoplankton growth. This research aims to determine phytoplankton abundance in biofloc ponds with different catfish stocking densities. Furthermore, a completely randomized design (CRD) was used, with four treatments and three replications. The treatments involved 1,000, 1,500, 2,000, and 2,500 catfish per m3, respectively, with a weight of ± 1-3 grams. Also, the fish was fed 3% of its body weight and reared for 40 days in a tarpaulin pond, with a water volume of ± 1,974 L. The AMOVA test was used to analyze the data and 10 phytoplankton genera were observed. However, the phytoplankton abundances showed no statistical significance among the treatments. The results showed that the first treatment had the most abundant phytoplankton, with an average number of 13,394 cell/L.Keywords:AbundanceBioflocCatfishDensityPhytoplankton

Abstract

Microplastics are particles that have a size of 5 mm, where its existence might be able to contaminate the biota in the aquatic environment. This research was conducted in the coastal waters of Bengkalis Island in December 2020 with the aim to determine the types and analyze its abundance of microplastics in each area with different sources of anthropogenic input in the north and south Bengkalis Island. Sampling of sea water for microplastic analysis was done using plankton net (diameter 30 cm and mesh size 30 μm) from six sampling stations. Thirty six individual samples of Duri (Arius maculatus), Lomek (Harpodon nehereus), and Biang (Setipinna breviceps) fish were obtained with the help of local fishermen in each sampling location. The results showed that the types of microplastics found in seawater samples are fiber and film with average abundance ranges between 9.58 particles/m3 - 40.42 particles/m3. The highest abundance was found in station 6 (60.83 ± 8.61 particles/m3 and 20.00 ± 8.94 particles/m3) for fiber and film, whilst the lowest abundance was found in station 3 (12.50 ± 5.24 particles/m3 and 6.67 ± 6.06 particles/m3) for fiber and film, respectively. The average abundance of microplastics found in the digestive tract of fish was 62.96 particles/ind. which consisted of fiber, film and fragment. The highest microplastic abundance was found in Duri fish (72.22 particles/ind.), whilst the lowest was found in Lomek fish (55.56 particles/ind.). Although the abundance of microplastic in coastal waters of north Bengkalis were higher than that in the south of Bengkalis Island, statistically they were significantly different. This was presumably due to differences in oceanographic influences such as current and waves between the two water masses as well as anthropogenic activities in both areas that can affect the spread and distribution of microplastics.Keywords: plastic waste, Bengkalis waters, demersal fish, pelagic fishABSTRAKMikroplastik adalah partikel yang memiliki ukuran 5 mm, di mana keberadaannya dapat mencemari biota di lingkungan akuatik. Penelitian ini dilakukan di perairan pantai Pulau Bengkalis pada Desember 2020 dengan tujuan untuk menentukan jenis dan menganalisis kelimpahan mikroplastik di setiap wilayah dengan berbagai sumber input antropogenik bagian utara dan selatan Pulau Bengkalis. Pengambilan sampel air laut untuk analisis mikroplastik dilakukan menggunakan plankton net (diameter 30 cm dan ukuran jala 30 μm) dari enam stasiun pengambilan sampel. Tiga puluh enam sampel individu ikan Duri (Arius maculatus), Lomek (Harpodon nehereus), dan Biang (Setipinna breviceps) diperoleh dengan bantuan nelayan lokal di setiap lokasi pengambilan sampel. Hasil penelitian menunjukkan bahwa jenis mikroplastik yang ditemukan dalam sampel air laut adalah fiber dan film dengan kisaran kelimpahan rata-rata antara 9,58 partikel/m3 - 40,42 partikel / m3. Kelimpahan tertinggi ditemukan di stasiun 6 (60,83 ± 8,61 partikel / m3 dan 20,00 ± 8,94 partikel / m3) untuk fiber dan film, sedangkan kelimpahan terendah ditemukan di stasiun 3 (12,50 ± 5,24 partikel / m3 dan 6,67 ± 6,06 partikel / m3) untuk fiber dan film. Kelimpahan rata-rata mikroplastik yang ditemukan dalam saluran pencernaan ikan adalah 62,96 partikel / ind. yang terdiri dari fiber, film dan fragmen. Kelimpahan mikroplastik tertinggi ditemukan pada ikan Duri (72,22 partikel / ind.), sedangkan yang terendah ditemukan pada ikan Lomek (55,56 partikel / ind.). Meskipun kelimpahan mikroplastik di perairan pantai Bengkalis utara lebih tinggi daripada di selatan Pulau Bengkalis, secara statistik mereka berbeda nyata. Ini mungkin karena perbedaan dalam pengaruh oseanografi seperti arus dan gelombang antara dua massa air serta aktivitas antropogenik di kedua daerah yang dapat mempengaruhi penyebaran dan distribusi plastik mikro.Kata kunci: sampah plastik, perairan Bengkalis, ikan demersal, ikan pelagis

Abstract

The marine environment is a rich sources of natural bioactive compounds which are not used optimally. It has been established that marine organisms contain a unique physicochemical characteristic that is very valuable to be applied for food industry and pharmaceutical. Recently, numerous study have been shown that compounds extracted from marine organisms possess various biological activities, including anticoagulant, anticancer and hypocholesterolemic. Moreover, fish oil and marine bacteria have been claimed as a source of omega-3 while crustaceans and seaweeds contained carotenoids and phenolic compounds. Based on a variety of biological activities of marine organisms, this review focuses on the potential use of marine-derived compounds as functional food ingredients and nutraceutical including some consideration of barriers for their application.Laut menyimpan sumber bahan fungsional yang relatif belum dimanfaatkan secara optimal. Karakteristik fisikokimianya yang kompleks dan tidak ditemukan pada biota terrestrial,   menjadikan bahan fungsional laut potensial untuk diaplikasikan dalam berbagai aspek seperti pengolahan makanan, pengawetan, fortifikasi dan industri farmasi. Selain itu, banyak penelitian menunjukkan bahwa senyawa yang diekstrak dari biota laut memiliki aktivitas biologis yang beragam. Sebagai contoh, peptida yang diisolasi dari hidrolisat protein ikan serta fucans, galaktan dan alginat dari alga telah terbukti memiliki aktifitas antikoagulan, antikanker dan hipokolesterolemik. Selain itu, minyak ikan dan bakteri laut merupakan sumber yang asam lemak omega-3, sedangkan krustasea dan rumput laut mengandung senyawa antioksidan seperti karotenoid dan senyawa fenolik. Berdasarkan beragam aktifitas bioaktif yang terkandung pada bahan laut, review ini berfokus pada potensi senyawa laut sebagai bahan pangan fungsional dan nutrasetikal sekaligus tantangan dalam pemanfaatannya.

Abstract

Chitosan is an ingredient that can be used as a feed additive. In aquaculture, chitosan can be used as an antimicrobial, antifungal, antioxidant growth-promoting and immunostimulant. This study aims to determine the optimum addition of chitosan to feed to increase growth and daily feed consumption of giant gourami. The method used in this research is an experimental method using a completely randomized design (CRD), which consists of five treatments and three replications. The treatments used were (A) without chitosan (control), (B) 2.5 g/kg feed, (C) 5 g/kg feed, (D) 7.5 g/kg feed, and (E) giving chitosan of 10 g/kg feed. The test fish used were giant gourami with a 6 – 8 cm length and a weight of 8 – 10 g. The container used was hapa measuring 1 x 1 x 1 m3 with a density of 15 fish per treatment and 42 days of maintenance. The feeding rate was 3% of the fish biomass. Data from observations of length and weight were analyzed using Analysis of Variance (ANOVA) with a 95% confidence level; if there was a significant difference, Duncan's multiple distance test was performed. The results showed that addition of chitosan 7.5 g/kg feed was effective in improving growth on giant gourami. During maintenance, absolute length growth was 2.90 ± 0.10 cm, absolute weight growth was 15.33 ± 1.19 g, daily growth was 36.51 ± 2.84%, feed conversion ratio was 1.69 ± 0.06, and survival rate was 100 ± 0.00%. This research concluded that the optimum level of addition of chitosan to increase growth and daily feed consumption of giant gourami was 7.5 g/kg feed.Keywords:ChitosanFeed additiveGiant gouramiGrowth

Abstract

Blue swimming crab (Portunus pelagicus) is the dominant catch in Betahwalang, Demak, and the most important export fish commodity, particularly to USA. The high demand for this crab has been promoting an excessive fishing effort, causing a decrease in the crab's natural stock. This study aims to investigate the biological condition of P. pelagicus on the northern coast of Central Java and assess the crab stock exploitation status in this study area. Carapace width, body weight, Gonad Maturity Stages (GMS), and sex of crab samples were collected from the fishers and collectors landing sites or meeting points. This study employs a simple random sampling technique with no replacement. This study revealed that the maximum carapace width of female crabs was 56-164 mm, and the estimated carapace width at first maturity (Lm) was 98.2 mm. The relationships between carapace width and body weight between male and female crabs indicated positive and negative allometric growth patterns. During this assessment, the P. pelagicus stock indicated an 'over-exploited’ status, with an LB-SPR parameter of 19 percent and an exploitation rate (E) of 0.66. Management measures such as minimum legal size, reduced effort, and open-close areas and seasons should be implemented to achieve sustainable use of the crab fishery.Keywords:Blue swimming crabFishing gearDemak watersCarapace lengthSpawning potential ratio

Abstract

 The purpose of this study was to identify the tiger shrimp (Penaeus monodon) histopatology status in traditional cultured ponds at Bireuen Regency, Aceh Province. The sampling was carried out by purposively random method from seven ponds and two shrimps were sampled from each pond. Several water quality parameters were checked like temperature, pH, salinity and ammonia. Result showed that black tiger shrimp (Penaeus monodon) which were cultivated in traditional ponds in the Bireuen Regency, Aceh Province were histopathologically changes. It was suspected the hepatopancreas changes were associated with viral infection like Hepatopancreatica Parvovirus (HPV) and White Feces Disease (WFD). Ammonia concentrations were found higher in some ponds like Alu Buya Village, Jangka Keutapang Village, Jangka Mesjid Village, Alu Kuta Village and Punjot Village. The management of regular feeding and water quality control is highly recommended to anticipate the viral potential attack in traditional shrimp pond farming at Jangka District, Bireuen Regency, Aceh Province.Keywords:Tiger shrimps Histopathology Water quality
