The waters of Aceh are surrounded by three major water bodies: the Andaman Sea, the Indian Ocean, and the Malacca Strait. Differences in current patterns extend the distribution range and contribute to the species diversity. Fish from the Scaridae family are among the species that thrive in these environments. The family Scaridae (Rafinesque 1810), commonly known as parrotfish, inhabits tropical seas, including the Pacific, Indian, and Atlantic Oceans, and is often found in coral reef areas. Parrotfish play a crucial role in maintaining coral reef health as one of the herbivorous fish species. This study aims to analyze the morphometric variation of five parrotfish species harvested from the Northern waters of Aceh. Traditional morphometrics using 12 measurement characters were applied to 60 fish samples from five species of the Scaridae family (Chlorurus capistratoides, Chlorurus sordidus, Scarus ghobban, Scarus niger, and Scarus rubroviolaceus). The results showed that Scarus rubroviolaceus shares four similar characters with Scarus ghobban: ED, HL, CPL, and PFL; it also shares four characters with Scarus niger: ED, HL, CPL, and SNL. Chlorurus capistratoides shares three similar characteristics with Scarus niger: CPL, ED, and PFL. In addition, the results of the DFA analysis revealed that Scarus ghobban and Scarus niger exhibit the highest degree of similarity in morphometric traits, particularly in HL, SNL, DFBL, ED, and PFL. Furthermore, Scarus rubroviolaceus demonstrates a slight overlap with Chlorurus capistratoides, while Scarus niger shows a minor overlap with Scarus rubroviolaceus. This study provides morphological diversity of parrotfish species in the northern Aceh waters.Keywords:Aceh watersmorphometricsParrotfishMeasurement charactersDFA

Global warming is caused by increased carbon emissions into the atmosphere resulting from burning oil, gas, and other fossil fuels. Subsequently, the carbon gas enters the waters through a diffusion process facilitated by the concentration of gases in the air, which is higher than in the waters. The outcome of this process is a decrease in water acidity, leading to a lower pH, which can disrupt the life of aquatic biotas. Therefore, this study aims to analyze the effect of decreasing of pH on the growth, survival, and physiological conditions of barramundi (Lates calcarifer). To achieve this objective, seven pH levels were tested, namely pH of 7.24 (control), pH 6.74, pH 6.24, pH 5.74, pH 5.24, pH 4.74, and pH 4.24. Every treatment was performed with four replications, and the fish was reared for 30 days in the respective tested pH. The reared madia is sea water with a salinity of 22 ppt. The experiment was conducted in the laboratory of fish breeding Faculty of Marine and Fisheries, Universitas Syiah. The results showed that a decreasing in pH had a significant effect on the growth performance and hematological condition of barramundi (P0.05), but its had no significant effect on survival (P0.05). The experimental fish could survive at pH 4.24, but their growth and hematological conditions were disrupted below 6.24. Therefore, it was concluded that the lower threshold value of pH for barramundi was 6.24.Keywords:Global warmingOcean aciditypHFisheries productionPhysiological disturbance

Shark is a cartilaginous fish that is widely hunted because it has high economic value. The waters of Aceh are directly adjacent to the Indian Ocean and the Malacca Strait making it a preferred habitat for pelagic fish, especially sharks. Information on shark species landed in the waters west and east of Aceh is very limited due to difficulties in identification and commonly used local names. This study aimed to determine the types of sharks landed in Banda Aceh, Meulaboh, Langsa, Southwest Aceh and Simeulu and to find out specifically what species of sharks are most often landed in Aceh waters. Primary data gathering consisted of four stages, namely sample collection, identification using identification books, molecular identification cytochrome oxidase subunit I (COI) and phylogenetic analysis. The results of the molecular analysis of 46 tissue samples from five locations identified 13 species of sharks, namely Carcharhinhus sorrah, Carcharhinhus amboinensis, Triaenodon obesus, Isurus oxyrinchus, Sphyrna zygaena, Sphyrna lewini, Loxodon macrorhinus, Hemipristis elongaria, Stagostoma fasciatum, Nebrius ferrugineus, Chilloscyllium punctatum, Isurus oxyrinchus, Alopias pelagicus, Alopias supercillosus and 1 species of rays, namely Rhynchobatus australiae. Phylogenetic tree reconstruction using the Neighbor Joining method of 610 basepairs consisting of two large clades separates the species Alopias pelagicus and Isurus oxyrichus with Carcharhinus sorrah, Sphyrna lewini, Loxodon macrorhinus and Rhyncobatus australiae with boostrap values of 87% and 64%. The haplotype diversity shown ranged from 0.667-0.889 while the nucleotide diversity ranged from 0.001-0.097. These values indicates high diversity because of the variance in the number of species found.Keywords:BarcodeCOISharks catchAlopias supercillosusSphyrna lewini

Research about succession of macro benthos on limestone substrate was conducted atthree sites (Klah Island, Gapang Beach and Gapang Mangrove) in the coral reef ecosystem of WehIsland from April â€“ December 2005. The selections of the sites are based on degradation of watersquality and coral reef condition. Limestone substrate as collectors were laid at 5 m waters depth ateach site, and further were taken after four and eight months. Succession pattern of macro benthoswas analyzed by Frontier Succession curve. The result shows that pattern of macro benthossuccessions were occurred significantly between locations and time. At site poor of natural coral reefcondition (Gapang Mangrove), succession pattern is in disturbance condition, while in Gapang Beachand Klah Island and Pulau Payung, which have good and fair coral condition, succession patterns aregoing in the direction of equilibrium condition. The result has indicated that waters quality is key factorfor macro benthos succession

Octopus cyanea is an ecologically and economically important cephalopod with wide larval dispersal influenced by ocean currents. However, geographic isolation among island clusters in northern Sumatra may restrict gene flow and shape population structure. This study investigated the genetic diversity and connectivity of O. cyanea from five populations (Aceh Island, Weh Island, Banyak Island, Simeulue Island, and Nias Island) using mitochondrial cytochrome c oxidase subunit I (COI) sequences. A total of 21 individuals were successfully amplified, yielding 651 bp fragments. Sequence analysis revealed 11 haplotypes across populations, with haplotype diversity (Hd) ranging from 0.285 in Banyak Island to 0.800 in Aceh Island, and nucleotide diversity (π) between 0.001 and 0.009. Pairwise genetic distances varied from 0.000 to 0.004, with the highest divergence observed between Simeulue Island and Nias Island (0.004), while Aceh Island and Weh Island showed no differentiation. AMOVA indicated that most genetic variation occurred within populations (68.74%), with an overall Fst of 0.315, suggesting low to moderate genetic structuring. The haplotype network demonstrated shared haplotypes among four populations, whereas Simeulue Island harbored unique haplotypes, indicating partial genetic isolation. These results highlight substantial genetic connectivity among O. cyanea populations in northern Sumatra, facilitated by larval dispersal via ocean currents, but also emphasize localized divergence in Simeulue Island. The findings provide critical baseline data for developing ecosystem-based fisheries management, supporting shared stock strategies while accounting for population-specific conservation needs.

Bottlenose Wedgefishes are fish that belong to the subclass Elasmobranchii, which are cartilaginous fish. West Aceh waters are one of the areas directly connected to the Indian Ocean. Bottlenose Wedgefish can be found in the Indian Ocean. Some information on Bottlenose Wedgefish DNA has now developed molecular approaches, which provide a fast and precise alternative to identify species. This research activity aims to report the presence of Bottlenose Wedgefish sharks (Rhynchobatus australiae) and analyze the relationship between Bottlenose Wedgefish sharks found in West Aceh with other regions. This research was conducted from October to December 2021. The specimens were taken from the Ujong Baroh Fish Landing Site (PPI), West Aceh, and analyzed at the Laboratory of Genetics and Aquatic Biodiversity, Faculty of Marine and Fisheries, Syiah Kuala University. The results of the study resulted in several conclusions, namely the Query Cover value of Meulaboh 1 and Meulaboh 2 samples of 93%. The Ident value of 99.70%-99.85% indicates that the same species is R. australiae. Thymine (T) nucleotide composition is 30.8%, Cytosine (C) is 24.9%, Adenine (A) is 27.4%, and Guanine (G) is 16.9%. Based on the results of phylogenetic tree reconstruction, the relationship between Rhynchobatus australiae Meulaboh samples 1 and 2 has a close kinship with Rhynchobatus australiae from India1, India2, India3, Malaysia1, Indonesia3, and Indonesia5. This research confirms the presence of Rhynchobatus australiae in West Aceh and establishes a close genetic link to regional populations.

BarramundiLates calcariferis a high economic value fish in Indonesia and Southeast Asia countries. However, the aquaculture system still experiences problems, including the high cost of production, specifically from feed, which is due to its relatively slow growth and low digestibility. Therefore, this study aims to determine alternative ingredients that can be used in the fish diet to improve feed utilization and growth performance using pumpkin flourCucurbita moschata. A completely randomized design (CRD) with 6 treatments and 3 replications was adopted in this study. The tested diet was (A) diet without pumpkin flour (control), (B) with 5% (C) 10% (D) 15% (E) 20%, and (F) 25%. The size of the Barramundi samples was 3-4 cm on average and the body weight was 1-3 g at the stocking density of 15 fish/container. The fish fed as much as 10% body weight daily, which is divided into 2 times, namely 08.00 AM and 4.00 PM for 60 days. The results showed that the addition of pumpkin flour had a significant effect on weight gain, daily and specific growth rate, survival, feed efficiency, conversion ratio, and carcass protein (P0.05). The diet with 5% pumpkin flour gave the best results over other treatments, with an average weight gain of 0.761 g, feed conversion of 1.578, feed efficiency of 63.455%, and a daily and specific growth rate of 0.012 g and 0.738%, respectively, The highest carcass protein content was found in the control treatment with a value of 18.210%, which was not significantly different from the 5% pumpkin flour treatment. Therefore, it is concluded that pumpkin flour can be added to the Barramundi diet as much as 5%.Keywords:Barramundi, Snapper, pumpkin,feed utilization
