Abstract

Sea urchins a biota that is often associated with seagrasses were often found in seagrass beds. The objectives of this research were to discover the condition of sea urchins and seagrass, such as diversity, uniformity, dominance in sea urchins, density, and cover on seagrass, and related to variables in this research. This research was conducted on Derawan Island. The research method that was used is a 5m x 5m (sea urchin) quadrate and 0.5m x 0.5m (seagrass) placed intentionally on 2 stations with a total of 30 quadrats. The results found 3 species of sea urchins and 4 species of seagrass. At station 1 abundance of sea urchins is 2.94 individual/m2 whereas at station 2 is 0,28 individual/m2. At station 1 seagrass density 117,33 shoot/m2 whereas station 2 is 120,13 shoot/m2. Seagrass cover at station 1 is 58,75% and at station 2 is 60,28%. The dominant sea urchin species is Diadema setosum with the following diversity values H'=0,36, E=0,3, and C=0.81. There was no significant difference between variables at each station except temperature (0.020<0.05) and DO (0.027<0.05). Variables that were correlated with sea urchins in the seagrass ecosystem are nitrate, salinity, phosphate, temperature, and pH. The association with seagrasses in Derawan Island is positive.

Abstract

Managing Mud Crab resources is the main thing that must be done to maintain the sustainability of these resources so that they can continue to make an economic contribution to society. A study of Mud Crabs that can be carried out is on morphometric trusses and their morphology. This research was carried out from April to June 2022 with sampling locations in mangroves in Pagarawan Village, Bangka Regency, and Kurau Village, Central Bangka Regency. The Mangrove Crab species found at sampling locations in Bangka and Central Bangka were Scylla serrata and Scylla tranquebarica. There are morphological variations in crab carapace color between sampling locations. The morphometrics of mud crabs from Bangka were larger but showed no significant differences. Differences in substrate type and environmental conditions are predicted to influence the emergence of variations. The location of the sampling locations, which are still connected to the same sea waters, allows the crabs to have close genetic and population relationships, making the variation insignificant.

Abstract

The rise of the world of ornamental fish in Indonesia has become a business opportunity for various groups. One of them is the ornamental snakehead fish or Channa pulchra. This fish comes from Myanmar and was imported to Indonesia to meet the needs of the ornamental fish market. One of the factors that influence the success of a fish farming business is the FCR and SR values. The lower the FCR value and the higher the SR value, the better the sustainability of the cultivation business. To maintain FCR and SR values, a good quality feed supply is needed. The aim of this research is to determine the effectiveness of supplementing pelleted feed in the form of Spirulina flour and butterfly pea flower flour (Clitoria ternatea), which contain nutrients to support growth and immunity so that they can improve FCR and SR values. The methods used in this research are quantitative and experimental methods. The experimental design used was a completely randomized design (CRD) with 12 containers filled with 1 fish/container. Data were analyzed using the ANOVA test which was carried out with Duncan's advanced test. Observation parameters include FCR value, SR value and water quality. The results obtained showed that there was an effect of providing different additional feeds on the FCR value with the best treatment being treatment A with a value of 3.6 ± 0.61. Treatment B has a value of 5.35 ± 0.21 and treatment K has a value of 4.05 ± 0.53. Meanwhile, the SR value does not show any influence from providing additional feed which is different from the value of 100% for each treatment parameter. Water quality results include a salinity value of 0 ppt, DO 7.16 ± 0.68 mg/l and temperature 29.62 ± 0.82 °C. The water quality value is still considered safe for cultivation unless the temperature is too high which is thought to influence fluctuations in the FCR value.

Abstract

Freshwater lobster (Cherax quadricarinatus) is one of the freshwater commodities that has the potential to be cultivated and has economic value. However, the problem still faced by farmers is the quality of feed which can affect low growth and survival. This research aims to analyze the growth performance of juvenile lobsters fed silk worms and rice flour. This research used 30 juvenile lobster samples measuring 1-3 cm (+ 1 inch) that were around 30 days old per aquarium. The parameters observed were body length, body weight, and survival rate (SR) of juvenile lobsters and the water parameters measured were pH, temperature, and total dissolved solids (TDS). The results of the research show that juvenile freshwater lobsters are able to consume silk worms and rice flour so that juvenile lobsters can be classified as omnivores. Feeding treatment in the form of a combination of silk worms and rice flour showed the best results for growth in length, weight and SR of juvenile freshwater lobsters. Juvenile growth during 32 days of rearing fed a combination of silkworm and rice flour resulted 4.30 cm + 0.02 cm in a length, 1.43 g + 0.01 g in weight, and SR 80%.

Abstract

Bangka Island is one of Indonesia’s regions with significant potential in terms of freshwater fish diversity, particularly within the genus Betta, commonly known as wild bettas. This study aims to document species diversity, geographic distribution, and natural habitat characteristics of wild Betta populations on Bangka Island, which inhabit peat swamp ecosystems, blackwater rivers, and abandoned tin-mining ponds. Through field exploration and morphological identification, seven primary Betta species were recorded: Betta burdigala, B. schalleri, B. edithae, B. chloropharynx, B. uberis, B. cracens, and B. simorum. Each species occupies a distinct habitat type characterized by extreme water parameters, including low pH (4.2–5.8), minimal dissolved oxygen levels (0.8–2.5 mg/L), relatively stable water temperatures (26–30°C), and low conductivity. Certain species, such as B. burdigala and B. chloropharynx, exhibit unique physiological adaptations via the labyrinth organ, which enables aerial respiration. The species distribution is uneven across the island, with some species being restricted to specific localities, rendering them endemic. Major threats to these species include habitat degradation due to tin mining, oil palm plantation expansion, and environmental pollution. Recent data indicate that several populations are experiencing severe declines, with some nearing local extinction. Consequently, the findings of this study provide a critical foundation for ecosystem-based conservation strategies and the restoration of vital habitats. Scientifically, Bangka Island qualifies as a Betta biodiversity hotspot of strategic importance in the context of Southeast Asian biogeography and the conservation of endemic freshwater species.

Abstract

Freshwater fish biodiversity in Belitung Island has undergone a significant decline due to extensive tin mining activities and the rapid expansion of oil palm plantations. In response to these ecological pressures, a biodiversity assessment was conducted in 2024 in the Lenggang River system—an ancient freshwater ecosystem located in East Belitung, Indonesia. The primary aim was to document native and endemic fish species and to establish a reintroduction-based conservation strategy tailored to the river's ecological context. Field surveys recorded high ichthyofaunal diversity, from which 32 native species were selected for reintroduction based on ecological value, conservation status, endemism, and their capacity to adapt to rehabilitated habitats. Among the prioritized taxa was Gymnochanda verae, a rare and endemic species found exclusively in the Bangka–Belitung region. Other selected species include Gymnochanda verae, Desmopuntius gemellus, Osteochilus spilurus, Osteochilus flavicauda, Eirmotus insignis, Brevibora cheeyai and Aplocheilus armatus. The reintroduction initiative was designed not only to restore declining populations but also to enrich the genetic diversity of native fish communities. Importantly, all reintroduced species were confirmed to be historically present and indigenous to the Lenggang River system. The conservation strategy was further supported by habitat restoration, local community involvement, and long-term population monitoring. Preliminary results indicate positive acclimatization in restored zones, underscoring the potential of species reintroduction as an effective tool for freshwater biodiversity conservation in ancient tropical river systems. This study provides essential baseline data and offers a replicable model for integrated conservation of freshwater ecosystems in Southeast Asia.
