Abstract

Coral animals have tentacles in which there are Nematocysts in the ectoderm layer and zooxanthella in the endoderm layer, and these two components have a role as a defense and food source; this study was conducted to identify the components of Montipora danae coral tentacles. The research was conducted in Marak Island, West Sumatra, with a purposive sampling method based on the presence of M.danae. The coral samples were decalcified to separate the tissue from the skeleton. The results of this study indicate that M.danae consists of Nematocysts type sH (small Holotrich), MpM-I (Microbasic p-Mastighopore I), and H (Holotrich). Holotrich has the highest relative abundance of 74-91%, MpM-I has 3,92-20,63% and sH has 3-24%. Holotrich has larger morphometrics than sH and MpM-I, namely 72,76-82,35 μm capsule length and 19,55-24 μm capsule width. The zooxanthella density of M. danae was lower than that of normal corals at 624 cells/cm2.

Abstract

One of the fisheries catches in Tanjung Jabung Barat is Fourfinger threadfin (Eleutheronema tetradactylum). Fourfinger threadfin is a commodity with a high economic value and has good taste, so many people catch it. Fourfinger threadfin is carried out continuously without considering the potential of the fish. If this continues to be done, it will cause a decrease in population. This research was conducted in August-October 2024. Secondary data on the results of the capture obtained from this study are data derived from the Tanjung Jabung Barat Fisheries Service from 2018 - 2022, including catches and efforts to catch Fourfinger threadfin. The data that was obtained was analyzed using Microsoft Excel. This research shows that the catch of Fourfinger threadfin in Tanjung Jabung Barat fluctuates every year. The highest CPUE value occurred in 2020, namely 3.688028, and the lowest was in 2021 at 1.28533. CMSY results and Optimum Effort of 727.4554 tons/year with Optimum Effort (Eopt) of 310,280 trips/year. With a Total Allowable Catch of 581.9643244. based on the data analysis that has been done, it can be concluded that the sustainable potential of Fourfinger threadfin in the waters of Tanjung Jabung Barat has not experienced overfishing. However, if there is an increase in fishing effort (trip), then the sustainable potential can be experienced in overfishing.

Abstract

This study aims to investigate the interannual variability of Sea Level Anomaly (SLA) along the western coast of Sumatra waters, focusing on the influences of the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) in modulating SLA patterns. Using 31 years (1993-2023) of a gridded dataset from Copernicus Marine Service (CMS) and climate indices as the reference, the interplay between SLA and climate modes (ENSO and IOD) was determined through lag/lead correlation and spatial distribution analysis. The analysis shows a clear inversive relationship between ENSO and SLA, with a one-month delayed negative correlation (r= -0.41), indicating that SLA increases during the La Niña phase due to shifting in atmospheric and oceanic conditions. Similarly, SLA exhibits a negative correlation with DMI (r= -0.46) without any lag, suggesting a rapid response of SLA to IOD. Spatial analysis further demonstrates that ENSO and IOD most strongly influence SLA along Sumatra’s coast within the first 1–3 months. These findings reveal that ENSO and IOD modulate SLA variability with distinct spatiotemporal characteristics, providing crucial insights for understanding coastal dynamics and enhancing mitigation strategy for sea level-related disasters in the western coastal region of Sumatra

Abstract

Pasta feed is an alternative replacement feed naturally occurring in cultivating Asian redtail catfish (Hemibagrus nemurus) larvae. However, pasta feed is not yet able to completely replace the Tubifex sp, and enrichment feed pasta with oils from mesenteric waste catfish is expected to improve the performance of pasta feed. This research aimed to determine the effect of enriching fermented pasta feed with waste oil from the mesenteric parts of catfish on the growth and survival of Asian redtail catfish larvae. This research used an experimental method with the design used, a Completely Randomized Design (CRD), one factor, and five treatments with three replications. This research was carried out from March to April 2024 at the Fish Hatchery and Breeding Laboratory, Fisheries and Marine Science Faculty, Universitas Riau. The research results show the influence of enrichment of fermented pasta feed with pangasius mesenteric fish oil on the growth and survival of Asian redtail catfish larvae. Given larvae feed fermented paste + fish oil from pangasius mesenteric waste 12 % produce growth and survival highest with an absolute weight of 1.63 g, absolute length of 5.33 cm, specific growth rate of 14.73%/day, survival of 84.44%, type A cannibalism index of 13.77%, and normal mortality of 1.77%. Water quality parameters such as water temperature range from 27-28.9 °C, pH ranges from 5-7, and DO ranges from 5.1-8.1 mg/L.

Abstract

This study was carried out in March-April 2024 in the intertidal zone of Bukit Batu District, Bengkalis Regency, Riau Province, with the aim of knowing the size distribution and the relationship between sediment organic matter content and the abundance of C. obtusa. This research uses a survey method by determining sampling stations using purposive sampling consisting of three stations. Each station has three transects consisting of plots measuring 3 m2. To determine differences in abundance, the Kruskal Wallis test was carried out and to determine the relationship between sediment organic matter content and the abundance of C. obtusa, statistical correlation and linear regression tests were carried out. The results showed that the organic matter content of the sediment is included in the medium-high category, ranging from 15.82%-22.27%. The abundance of C. obtusa ranged between 5.12−6.96 ind/m2. There were differences in the abundance of C. obtusa among stations, with details between stations 3 and 1 and stations 3 and 2 being significant, while between stations 1 and 2 it was not significant. There were no differences in the abundance of C. obtusa among intertidal subzones. The distribution of C. obtusa is clustered with a dominant size of 20.7−34.5 mm. There is a moderate relationship between sediment organic matter content and the abundance of C. obtusa with a correlation coefficient (r) of 0.4743 and interpreted in the equation Y = -0,0009 + 0,2775X

Abstract

The Dumai City area is one of the regions currently designated as an industrial zone, a transportation route, and a busy international port. This situation puts significant pressure on the marine waters of Dumai City due to the waste produced. The primary source of marine pollution comes from oil spills, whether from ship operations, offshore drilling, or ship accidents. Pollution from oil spills in the ocean is a significant source of marine contamination that has consistently been a focus of public attention. This study aims to analyze the total oil content, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), and Total Organic Matter (TOM), as well as the effect of total oil content on DO, BOD, and TOM. The survey method used in this research involves collecting data from DO, BOD, TOM, and oil content measurements. The total oil content in Dumai City waters ranges from 0.14485 – 0.30214 ppm. The total oil content below the threshold still supports aquatic biota and does not damage the ecosystem. The DO content in Dumai waters ranges from 3.6 to 6.8 mg/L, and some measurements are below the threshold required to support marine biota. The BOD content of Dumai waters ranges from 10 to 11.3 mg/L, meaning that biological activity is still within optimal limits. The TOM content ranges from 17.38 – 35.22 mg/L, which does not support the life of aquatic biota, and there is potential for organic material pollution

Abstract

Striped catfish (Pangasianodon hypopthalmus) is well known in Asia, specifically in Southeast Asia, such as Vietnam, Thailand, Indonesia, Malaysia, Cambodia, Burma, and Brunei Darussalam. Currently, catfish have been exported to almost all countries in the world. This study aims to analyze the chemical composition of processed catfish by-products and find alternatives for their economic utilization. The research method used is the experimental method, namely conducting experiments on using processed by-products of catfish as food raw materials. Furthermore, quality analysis was performed on processed by-products and raw food materials, namely proximate analysis and amino acid profile. Proximate analysis of processed catfish by-products (meat attached to bones, belly fat, fish bones, and offal) includes protein, fat, water content, carbohydrates, and amino acids. These by-products are still classified as functional. Therefore, this research utilizes these by-products in food raw materials. The chemical analysis (proximate) results of the products produced showed numbers that meet SNI quality standards as food products. By-products of catfish processing (fillets and smoked catfish) can be utilized as food raw materials in the form of fish concentrate flour, fish bone meal, and fish oil
