Abstract

Batu Bara Regency is a region with abundant natural resources, one of which is the cultivation of grouper fish. Grouper is a member of the Serranidae family of coral reef fish. Many groupers are raised in ponds, which makes them susceptible to disease due to environmental and dietary factors that are not adapted to grouper fish, which is a native species. Parasites are one of the grouper-infecting diseases that, if left untreated, can result in mass mortality and harm farmers. The aim of this study was to identify parasites in ponds in Mesjid Lama Village, Talawi District, so that it would be easier to determine the type of parasite, its level of attack, and subsequent efforts to eradicate it. This research employs a sampling technique, specifically a random sampling of orange-spotted grouper. The results of the performed analysis include analyses of both ectoparasites and endoparasites. Several types of ectoparasites were identified, including Cryptocaryon irritans, Pseudorhabdosynochus sp, Benedenia epinepheli, and Caligus sp, while Prosorynchus sp was identified as the endoparasite. The most prevalent parasite found in the fish is Cryptocaryon irritans.Keywords: EndoparasiteParasitesGrouper

Abstract

The waters of Palabuhanratu Bay are fertile and rich with fish resources. For a long time, fishermen have used the fish resources in these waters. Hairtail (Trichiurus sp.) was one of the fish resources in Palabuhanratu Bay that caught by fishermen using handlines. Fishery production landed at Palabuhanratu Fishing Port in 2019 was 5,414,240 kg with a total hairtail production of 314,107 kg. The problem raised in this study was knowing the right hairtail fishing season so that it provides optimum benefits for fishermen. In addition, knowing potential fishing areas could assist fishermen in choosing their fishing time and fishing ground. The purpose of this study was to describe the hairtail fishing unit, to analyze the catch composition of handline, to analyze the fishing season patterns of hairtail fish, and to analyze hairtail fishing ground in Palabuhanratu bay. The results of the analysis showed that the fishing season for hairtail (Trichiurus sp.) in the waters of Palabuhanratu Bay lasts for 5 years with the peak in October. However, the reality is that fishing operations can be carried out throughout the year. The average catch per unit effort (CPUE) of hairtail (Trichiurus sp) duringfishing seasons was 11.32 kg/trip in 2019. The potential fishing ground was in the waters of West Ujung Genteng, Southern waters of Sawarna, Southern waters of Karanghawu and the waters of West Ujung Karang Bentang.Keywords:Fishing season patternHairtail fishFishing groundPalabuhanratu Bay

Abstract

Baby crab consumption has become a growing trend in snack markets across Asia, with rising popularity in at least five countries. Cirebon, situated on the coast of West Java, is a region experiencing particularly high demand for baby crab commodities, notably the locally known "kroyo" crab. However, without adequate information on this species, its future stock sustainability may be compromised. Indonesian regulations governing high-value Crustacea commodities, outlined in Ministry of Marine Affairs and Fisheries Regulation Number 16 of 2022, include lobster (Panulirus spp.), mangrove crab (Scylla spp.), and blue swimming crab (Portunus spp.). This study employs both morphological and molecular analyses, utilizing DNA barcoding techniques. Male (AMJ) and female (AMB) crabs were collected in February 2023 from Gebang Waters, Cirebon, Indonesia. Morphological identification followed guidelines established by the Food and Agriculture Organization (FAO) for crabs, while molecular identification utilized the Cytochrome Oxidase I (COI) gene. Morphological features such as carapace characteristics, front-orbital border, and cheliped spine morphology categorize the specimens under the genus Charybdis. Specifically, the presence of two spines in the cheliped indicates classification as Charybdis anisodon, a conclusion supported by molecular analysis revealing a 98.9298.96% similarity with C. anisodon. Further analysis of the stock of this crab species is necessary to enhance awareness of its exploitation and inform sustainable management practices.Keywords:Baby crabDNA barcodingFisheries managementIdentificationMorphological

Abstract

Noise pollution, or unwanted sounds in the ocean, can have a negative impact on marine mammals, especially on their biological behaviour when hunting for prey and changes in diving habits when leaving their habitat. This noise study was carried out in the waters of Samarinda with the help of a passive system acoustic instrument, which captures the range of sound intensity in the water column and supporting data in the form of sound range and activity above sea level. The sound range of 38.10-78.60 dB (A) above the water surface is safe for both everyday activities and as a habitat for mammals. Similarly, the underwater sound intensity between 0.84 and 138.47 dB re 1 Pa falls within this range. The noise condition in the study area is still expected. It can be used as an initial reference for the tolerance of sound intensity that applies to living things around the research location. The noise of the sea in Samarinda's waters has no effect on the lives of animals.Keywords:NoiseSound intensityMarine mammalHydrophoneSmartNoise

Abstract

Nile tilapia is a freshwater fish that is widely cultivated in Indonesia. During its development, tilapia aquaculture has constraints such as low growth rates. Therefore, it is necessary to add a feed additive to the feed in the form of charcoal. Charcoal is an adsorbent that has high absorption so that the addition of charcoal in the feed can increase the absorption of nutrients of tilapia. A 45-days trial was conducted to determine the percentage of addition of triggerfish bone charcoal (Abalistes stellaris) as a feed supplement that affect the growth performance and intestines of tilapia. The research design was a non-factorial Completely Randomized Design (CRD) with 4 treatments and 2 replications as treatments including: treatment A (control), B (addition of 1%charcoal), C (addition of 2% charcoal) and D (addition of 3% charcoal). A total of 240 tilapia fingerlings (5-7 cm) were used and placed in 8 aquariums then filled with 72 liters of water. Providing adlibitum (unlimited) feed with a frequency of 2 times a day. The ANOVA test showed that the addition of triggerfish bone charcoal (A. stellaris) in the feed was not significantly different (P 0.05) in weight growth, absolute length and daily length growth but it was significantly different (P 0.05) in feed conversion ratio and the efficiency of feed utilization. Based on result, it was concluded that the addition of 3% charcoal was the best treatment which gave the lengthiest of villi which was increasing the length of the intestinal villi to 71.11 µm from the initial length of 162.22 µm. easel at 233.33 μm, showed the highest feed conversion ratio value and feed efficiency (1.12 %, 89.6%).Keywords:CharcoalFish boneIntestinal histologyStarry triggerfish

Abstract

Abstract. Pomacentridae has a wide distribution in Indonesia waters. Research on species richness of Pomacentridae has been carried out in some areas in Indonesia. However, there are no data about the relationships of Pomacentridae on the southern coast of West Java. This research aims to know the evolutionary kinship of Pomacentridae ornamental fish in Ujung Genteng and Taman Manalusu Beach, West Java. This research used a survey method with a judgment sampling technique. The parameters measured were the consistency index (CI) and character evolution of the resulting phylogenetic tree. Cladogram reconstructed based on maximum parsimony algorithm with 1000 bootstrap replicates in PAUP software. The result showed that the tree had a CI value of 0.6000 which indicated low homoplasy. Pomacentridae formed a monophyletic group when they compared with Chaetodon collare as outgroup. The Pomacentridae clade divided into two subclades. The first subclade consisted of Abudefduf indicus as a basal species, then Neoglypydodon bonang and Plectroglyphidodon lacrymatus have a closed kinship and diverged after Dascyllus trimaculatus, and then Abudefduf notatus and Abudefduf sexfaciatus have a close kinship and diverged after Abudefduf vaigiensis. The second subclade referred to as a basal group, and within this subclade, Chrysiptera brownriggii has a closely related to Chrysiptera unimaculata and diverged after Chromis opercularis.Keywords: Cladistics, damselfish, meristic, morphometric, Pomacentridae
