Abstract

Samalona Island is a small island that administratively belongs to the inner zone of the Spermonde Islands region with low live coral cover. One effort to improve coral conditions is to carry out vertical transplantation, but hydro-oceanographic conditions are thought to be an inhibiting factor, including sediment. The research carried out aims to determine the suitability of oceanographic parameters, estimate sediment rates, and determine the phosphate and nitrate in sediments. The research method used a field experiment method by taking water and sediment samples and installing sediment traps for 15 days. The parameters measured in situ are temperature, pH, current speed, salinity, and dissolved oxygen, while the ex-situ test is the dry weight of sediment, TSS, nitrate, and phosphate concentrations. Data analysis uses descriptive statistics and is categorized according to the evaluation instrument used. The research results show that the values for temperature, pH, current speed, salinity, and dissolved oxygen meet the standard criteria for coral-based on PP 21/2022. The sediment rate during the research period was 0,003 – 0,015 gr/cm2/day, so it was categorized as having the potential damage to corals with a mild to severe impact level. The nitrate concentration in sediment ranges from 0,19 – 0,25 ppm while phosphate ranges from 0,35 – 0,72 ppm, so it can be said to be waters with a medium trophic level (mesotrophic). The current speeds and sediment rates potentially accelerate nutrient concentrations and cause sediment resuspension, thereby closing coral polyps, especially on corals closest to the substrate where vertical coral transplant installations are installed.

Abstract

Koi fish (Cyprinus rubrofuscus) is one of the aquaculture commodities that is highly marketable because of its unique color pattern and body shape. The prevalence of parasites and pathogenic agents in Koi fish among farmers poses challenges and leads to the occurrence of numerous illnesses. Water quality management is implemented in an effort to prevent several infectious microorganisms. The application of a recirculation system is used to enhance water quality and bolster the disease resistance of Koi fish. The objective of this study was to evaluate the application of RAS technology in the koi fish culture under different filter media on bacterial density. This study used four treatments, namely treatment A (RAS with a dacron filter and pumice), B (RAS with a dacron filter and sand), C (RAS with a sand and pumice filter), and K (control without a recirculation system). The parameter observed in this study was the density of bacteria in the koi fish rearing-media. These findings demonstrated that the utilization of various filters had an impact on bacterial density. Treatment C (RAS with sand and pumice filter) exhibited the greatest bacterial density with an average value exceeding 3.4 log CFU. mL-1 from the first week to the third week. The density of nitrifying bacteria in the koi fish production system is positively influenced by the high-quality maintenance practices that are maintained under optimal conditions.

Abstract

Sea turtles are one of the living fossils that still exist. There are only 7 species of sea turtles in the world. Sea turtles have encountered many threats, even since they were still in the egg on the nesting beach. The nest of turtle eggs on the beach have some threats like predators, theft, sabrasion and coastline changes that increase the action of relocation of turtle nests are needed to save the eggs. Ths study aimed to know the estendency of native places from the eggs which are relocated to semi-natural nests at Turtle Conservation and Education Center, Serangan-Bali. The data was collected from 2015 until 2019. In 5 years the number of nest rescued was 792 and the number of eggwas 87.303. The nest which relocated to semi-natural nest in TCEC came from 27 nesting habitats. Mostly the nest native to Klungkung beach, Serangan beach, and Lembeng beach with the number of turtle eggs on each beach were 211 nests, 179 nests, and 174 nests.

Abstract

The potential of fisheries resources in Merauke Regency is very high, both in marine and inland including swamp waters. However, swamp waters in this Regency are relatively low to be utilized. This research was held in Swamp Ecosystem located in Wasur Village, Merauke Regency. The purpose of this study was to determine the effect of the various types of bait on the catch of fish, especially Snakehead fish by using one type of fishing gear known as traps. The benefit is to be able to provide additional information to the public about the type of bait most favored by Snakehead. This study used experimental fishing methods and further analyzed using a completely randomized design with three different bait treatment types: ants, frogs, and worms. The results showed that the percentage of fish caught using ant bait reached 53%, followed by frog bait at 28%, and worm bait at 19%, respectively. Overall, this research reveals that ant is the most preferred bait by Snakehead fish compared with two other baits.

Abstract

The conservation Area (lubuk larangan) is one of the fish resource conservation areas. However, recently, the types of fish that live in this area have become increasingly threatened due to environmental changes and non-selective fishing. Therefore, it is important to study the diversity of freshwater fish in the conservation area (Lubuk Larangan) located along the Bangko River, Luak Kapau Village, South Solok Regency, West Sumatra Province, Indonesia.  This data will be valuable in determining which fish species should be prioritized for domestication as potential candidates for fish cultivation. The process of collecting fish is carried out between June and July 2020 by involving the assistance of local fishermen who use various types of fishing gear, including gill nets, spread nets, trap nets, and fishing rods. The findings from this study revealed the existence of 13 fish species belonging to three orders, six families, and thirteen genera. Among the species collected, the family Cyprinidae was the most dominant, accounting for 61.53% of the total fish population collected, followed by the families Cobitidae, Bangridae, Cichlidae, Mastacembelidae, and Gobiidae, each consisting of 7.69%. of the total. The species Acanopsis octoactinotus was identified as vulnerable, while Sicyopterus aeinsis was classified as near threatened. The level of functioning of the conservation area for fish preservation is 84.35%, which is included in the very well functioning category. Priority should be given to breeding programs and restoration initiatives targeting future populations of endangered freshwater fish.

Abstract

Research on the whale shark (Rhincodon typus) is carried out in the Kwatisore waters, part of the Cenderawasih Bay National Park (CTNP), Papua, Indonesia. Field observations were conducted for 4 months, from September to December 2016. The objective of the study was to look at the distribution and behavior of whale sharks based on weather conditions, time and place of appearance. The collecting of whale shark data was done by direct observation method which was divided into 2 observation time that is direct observation by researchers between 06.00-17.59 WIT and indirect observation by lift-net fisherman between 18.00-05.59 WIT. The distribution of whale sharks will be analyzed using Geographic Information System (GIS) through digitization process and overlay based on coordinate point. The results of observation and data analysis showed that the frequency of whale shark emergence at 06.00-11.59 WIT is much higher than at 00.00-05.59 WIT that is 148: 18 times. The low frequency of occurrence of these fish at night because in every observation at night, it is difficult to find an individual whale shark that appears. Whale sharks are more visible when the weather is sunny, compared to overcast or rainy days. The results of behavioral observations show that 64% of whale sharks appear to be eating. The rest is playing and just passing by. This is because whale sharks are heavily dependent on the main food of plankton that often lies just below the surface of the waters and or on the surface of the waters.

Abstract

Bagan are classified as lift nets and use light as an attraction. Ohoi Selayar is a fish-producing center in terms of capture fisheries. Fishermen generally use bagan, in one night 3-4 times hauling with a net immersion time of 2.5-3 hours, but based on the results of our survey there is a boat bagan that operates in one night only twice hauling with a net immersion time of 4-5 hours, for this reason this research was conducted with the aim of analyzing the composition of the catch and determining the optimal hauling time for fish catches on lift net in Ohoi Selayar Waters of the Kei Islands. The method used in this research is experimental fishing method, data analysis using t test by comparing the catch of boat trawl based on hauling time. The types of fish caught on the lift net for 10 days, generally small pelagic fish species. The arrival of this type of fish is thought to be due to direct attraction by light and foraging, namely; species of Anchovy (Stolephorus sp) with a total weight of 3,020 kg (61%), Layang (Decapterus spp) weighing 1628.6 kg (33%), and squid (Loligo) 294.2 kg (6%). Based on the results of the t-test analysis comparing the total catch of the boat between hauling times I and II, the t-count of 2.525 is greater than the t- table of 1.372 at the 90% and 1.812 95% confidence levels, indicating a significant difference between hauling times I and II on the boat. Thus, technically, hauling time II of the boat chart shows an increase in catch and is effectively able to respond to the distribution of fish around the lights when compared to hauling time I.

Abstract

The fish apartment is one of the concepts of artificial structures on the seabed where the design and construction are created to resemble the conditions of natural reefs. The fish apartment is designed with concrete material which is combined by utilizing waste pearl shells with the same construction but different in the application of the use of shells. This study was carried out for 6 months with 12 observations, which aimed to examine the treatment preferences of the fish apartment that have an impact on the presence of fish in the vicinity. The fish apartment is placed in two different locations to see the preference of the fish in the fish apartment. Data was collected using the visual census method to determine the effect of the fish apartment on the presence of fish using data analysis of variance (ANOVA) with the factorial randomized block design experimental method. The assessment of the effect of fish apartment on the presence of fish was carried out by treating the fish apartment construction itself, and other treatments that were also tested were sampling time, placement position, and repetition (groups). The types of fish observed in the fish apartment and its surroundings were 19 families on good coral reef locations, and 15 families on damaged coral reef locations. The number of fish observed was more in a fish apartment without pearl shells.

Abstract

Acanthaster planci is one of the most potential causes of coral reef damage in Indonesia. The presence of A. planci in Indonesia has been reported with a large population and preys on corals with large numbers. This research as conducted in order to provide information quickly related to the category of A. planci hems in the Sombori tribe. The monitoring method used is the time s imming method hich is carried out for 2x10 minutes. Categorization of outbreak determination using threshold approach developed in the ORANET (Oceania Regional Acanthaster Network) program. Monitoring the abundance of A. planci as carried out in seven locations with 10 observation points, namely Dongkalan Kecil Island with 123 individuals, Dongkalan Besar Island with 5 individuals, Mbokita Island with 60 individuals, Kayangan Island with 7 individuals, Red Sand Beach with 5 individuals, Air Kiri Beach with 6 individuals, and Goa Alo Beach with 6 individuals. The high number of A. planci individuals is only found on 2 islands, namely Dongkalan Kecil Island and Mbokita Island. The number of A. planci on these t o islands is included in the category of possible outbreaks and is included in the category of threatening coral reef ecosystems. The condition of coral reefs on Dongkalan Island is small dominated by dead corals thought to be due to predation of A. planci. hile on Mbokita Island, the condition of coral reefs is not dominated by dead corals but there are many remnants of predation on corals.

Abstract

Fishing with explosives (fish bombs) is one of the cases of destructive fishing that occurs every year on the coast of Saleh Bay, Sumbawa, West Nusa Tenggara. The government has implemented several strategies to reduce destructive fishing, but these cases still occur on the coast of Saleh Bay. This research aims to determine fishermen's perceptions and principles regarding fishing using bombs. This research was conducted from June to August 2023 in Prajak Hamlet, Batu Bangka Village, Sumbawa, West Nusa Tenggara (NTB). The method used in this research is a survey. The survey was conducted through in-depth interviews with respondents. The number of respondents in this study was 50 people. Data were analyzed using descriptive analysis. Data is displayed with graphs. The research results show that there are still 2% of fishermen who think that bombs are a cheap fishing tool, produce abundant fish and are easy to operate. There were 2% of respondents who stated that there was nothing wrong with using bombs. The act of bombing fish was imitated by previous people. As many as 4% of fishermen are not sure that their actions will have an impact on the ocean. The majority of fishermen (72%) have a high level of confidence in using fishing gear recommended by the government, but there are 8% who feel unsure about using fishing gear recommended by the government. The results of this research indicate that there is still potential for fish bombing in the waters of Saleh Bay. Therefore, outreach activities are needed for fishermen regarding the impacts of using fish bombs.
