Abstract

Environmental problems due to aquaculture occur along with the increase in aquaculture production. IMTA is one system used as a solution in dealing with environmental problems. The objective of this study was to analyze the growth performance, survival rate, and production of the main commodity (tilapia) and the supporting commodities (Peres, Lemeduk, and Depik) which are applied through the application of integrated multi-trophic aquaculture (IMTA) using floating net cages. This research was conducted at the Lukup Badak Fish Seed Center, Central Aceh from July to August 2020. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 replications, namely: A (tilapia), B (tilapia and peres), C (tilapia and lemeduk), and D (tilapia and depik). ANOVA test results showed that the IMTA system had a significant effect on absolute length growth, absolute weight growth, specific growth rate (SGR), survival rate, and biomass production of tilapia (P0.05). The results showed that maintenance for 42 days produced the highest value in treatment B with the increase in absolute length growth (4.26cm0.24); absolute weight growth (5.47g0.45), specific daily growth rate (2.28%/day0.13) and the highest tilapia biomass production (480g/0.5m219.25). The highest survival rate was found in treatment C (82.42%2.28). It was concluded that the treatment using the IMTA system was better than without the IMTA system.Keywords:IMTAWater qualityGrowth performanceTrophic interactionBiomass production

Abstract

Indonesia is recognized as one of the territories that have the highest reef fish biodiversity in the world. One of the commercially valuable fish in this area is the groupers (locally name "kerapu"). At least 76 grouper species have been reported in Indonesian waters, with three species were categorized into "vulnerable", five species "Data Deficient", and 68 species under the "Least Concern" category based on IUCN classification. The increasing exploitations rate had been reported caused the grouper stocks in Indonesia to decrease and threatened extinction. However, only limited scientific data is available regarding the grouper in Indonesia, including their identification. In most fish landing sites across Indonesia, the groupers are morphologically identified and recorded as "kerapu" to replace their scientific species names. Accurate species identification is essential in designing appropriate and sustainable management of fisheries resources. One of the tools that have been used in fish identification is DNA barcoding. In the last two decades, this molecular method has been applied to identify many fish groups globally, including grouper fish. This study reviewed the DNA barcoding approach in grouper identification in Indonesia based on the available literature.Keywords:DNA barcodingGrouperMolecular TaxonomyFisheriesIndonesia

Abstract

Coral reef ecosystems have a vital role in waters so that damage to coral reef ecosystems can reduce ecological and socio-economic functions that can impact environmental imbalances, such as reef fish and benthic communities. This study aims to determine the effect of transplant media on the growth rate of the genus Pocillopora coral and see whether it has a significant effect on the rate of coral growth in TWAL Pulau Weh, Aceh Province. The method used is a purposive sampling method in determining stations, analysis using the ImageJ 1.52 application. The results showed that the effect of transplant media on the growth rate of Pocillopora corals were significant differences between structures given an electric current and those not given an electric current with a 95% confidence interval. The average growth value of Pocillopora corals given an electric current is 25.06 mm/month. While the Pocillopora corals that were not given an electric current average growth value was 16.50 mm/month.Keywords:Coral reefCoral transplantElectrical stimulationPocilloporaImagej

Abstract

The development of infrastructure could be one of a threat to habitat of horseshoe crabs. Regarding that, constructing of an international port at Kijing Beach in Mempawah could also become a menace to crabss habitat. Carcinoscorpius rotundicauda is known to be the most commonly found in Mempawah Mangrove Park (MMP) coastal area. This study aim is to analyze population structure and morphometry of Carsinoscorpius rotundicauda in MMP coastal area. Research was conducted on April-September 2022. Fishers collected horseshoe crab samples using trammel net. This study observed 14 characters and four ratios of morphometric, i.e. total length (TL), prosoma length (PL), opisthosoma length (OL), telson length, prosoma width (PW), carapace length (CL), compound eyes distance (CED), anal angle length (AAL), posterior angle distance (PAD), telson width (TW), median ridge length (MRL), anterior occeli length (AOL), process marginal length (PML), body weight, PL/OL, PW/PL, CL/TL, and CL/PW. The number of individuals of horseshoe crabs found high on September. The sex ratio of males to females was 1,95:1. The highest frequency relative of prosoma width was found in the range around 1214 cm (adult size). The ratio of PW/PL of female crab was significantly bigger than male. This difference could be used for determining sex of this species crabs. The growth pattern of mangrove horseshoe crabs bot males and females were negative allometry.

Abstract

Lingula anatina or also known as baree is an animal that has legs and no spine. Baree is one of the few marine avertebrates that has the most complete fossil record, this species can play a role in ecological monitoring and maintaining the health of marine ecosystems. This study aims to identify and analyze the types of ectoparasites and endoparasites as well as measure the prevalence and intensity of infection in Lingula anatina (baree) at Ujung Pancu Beach, Aceh Besar. The results showed the presence of ectoparasites Pedicellina cernua (Entoprocta) and Unitubilotestis sp. (Platyhelminthes), as well as endoparasites Perkinsus spp. (Perkinsozoa) and Hysterothylacium aduncum (Nematoda). The prevalence of ectoparasite infection ranged from 0.08%, with an intensity of 1 individual per sample, while the prevalence of endoparasites ranged from 0.03%-0.22% with an intensity of 1.45-2.81 individuals per sample. These findings add insight into the parasites infecting Lingula anatina and contribute to ecological monitoring and marine ecosystem health.Keywords:L. anatinaFilter feederNematodaPlatyhelminthes

Abstract

Provinsi Kepulauan Riau memiliki potensi perikanan yang tinggi karena didominasi oleh wilayah perairan dibandingkan daratannya. Potensi perikanan yang tinggi tersebut diantaranya adalah komoditas rajungan. Pandemi covid-19 di seluruh dunia berpengaruh terhadap berbagai sektor, salah satunya sektor perikanan rajungan, sehingga informasi biologi (bioinformasi) dalam masa pandemi ini sangat bermanfaat untuk kegiatan perikanan rajungan berkelanjutan di Kabupaten Bintan. Tujuan penelitian ini untuk memberikan bioinformasi terkait rajungan dalam masa pandemi covid-19 di Kabupaten Bintan. Bioinformasi tersebut meliputi distribusi ukuran, pola pertumbuhan, nisbah kelamin jantan dan betina, serta tingkat kematangan gonad rajungan betina di perairan Kawal dan Pengujan. Ukuran lebar karapas rajungan di Kawal berkisar antara 102,2–187,9 mm dan ukuran lebar karapas rajungan di Pengujan berkisar antara 106,3–148,4 mm. Modus kelas lebar karapas ditemukan pada nilai tengah kelas 130 mm (di Kawal) dan 140 mm (di Pengujan). Pola pertumbuhan rajungan baik betina maupun jantan di Kawal dan Pengujan bersifat allometrik negatif. Berdasarkan uji chi square dengan tingkat kepercayaan 95% (α = 0,05), nisbah kelamin rajungan jantan-betina secara umum baik di Kawal maupun di Pengujan pada kondisi yang seimbang. Tingkat kematangan gonad (TKG) pada rajungan betina secara keseluruhan ditemukan mulai dari stadia TKG 1 sampai stadia TKG 4. Di perairan Kawal ditemukan sebesar 67% matang gonad, 22% belum matang gonad, dan 11% berried female. Di perairan Pengujan ditemukan sebesar 31% matang gonad, 63% belum matang gonad, dan 6% berried female.
