Abstract

Coastal ecosystems in Ternate have high biodiversity, including the macroalga Caulerpa racemosa, which contributes to ecosystem stabilization and mitigation of ocean acidification. However, environmental degradation due to human activities poses a serious threat, so analyzing the distribution and density of macroalgae is important for sustainable ecosystem management. This study aimed to analyze the distribution pattern and density of C. racemosa in Kastela and Gamalama waters, Ternate City. Data collection was conducted from May to August 2024 using the line transect method with 1x1 m quadrants in two research locations. Each site had three 50 m long transect lines with five quadrants per transect. Density was calculated based on the number of individuals per unit area, while distribution patterns were analyzed using the Morisita index (Id). Environmental data such as temperature, salinity and pH were also measured to understand the factors affecting macroalgae distribution. Spatial analysis using GIS software visualized distribution patterns. Results showed that C. racemosa had a concentrated distribution pattern (Id 1) in both study sites, with higher average densities in Kastela waters than Gamalama. Environmental factors, including temperature and substrate type, significantly influenced the distribution of this species. This study provides important data to support ecosystem-based management and sustainable coastal conservation, and fills an information gap on the impacts of ecological pressures on macroalgae in this region.Keywords:Caulerpa racemosaTernateDistributionCoastal Ecosystem

Abstract

The Optimal coral reefs are distributed in shallow waters between 0 and 30 m deep, influenced by the hydro-oceanographic variability of the waters. Globally, corals are distributed in various forms of water predominantly found in the Coral Triangle region. This study aims to examine the spatial distribution of coral biodiversity in the Tidore Island Waters. This study was conducted in the Tidore Island Waters at three research stations, namely Tugulufa Station, Toloa Station and Tanjun Konde Station. This study analyzed the spatial distribution of coral and the relationship between coral biodiversity and the hydro-oceanographic conditions of the Tidore Island waters. The results showed that the highest coral diversity was found at Toloa Station, with the largest area being the Acropora tabulate coral life form. Acropora coral species were found throughout the research location, with the highest percentage of cover found at Toloa Station. Temperature and salinity variables are the main characteristics in the three research locations. Temperature has a role and main characteristics in Toloa Station. The spatial distribution of Acropora corals is related to temperature and salinity variability.Keywords:Coral reefTidore waterTemperatureSalinity

Abstract

The Ecopath mass-balanced model was employed to elucidate the trophic structure and interaction, energy flow, and ecosystem properties of the coral reef ecosystem in the coastal area of Ternate Island. The model comprised 30 functional ecological groups, of which 29 were living groups and one was a group of detritus. The trophic structure of the model exhibited a range of values, from 1.0 for primary producers and detritus to 3.81 for the top predator. The resulting trophic aggregation comprises six effective trophic groups, with the largest energy flow originating from zooplankton and benthic organisms in trophic level II. The transfer efficiency is predominantly derived from detritus organisms, in comparison to that derived from phytoplankton as the primary producer. The ratio of total primary production per total respiration indicated that the coral reef ecosystem was at a developmental stage. The coral reef ecosystem exhibited a low ecological efficiency for the fishery gross efficiency. Mixed trophic impact analysis indicated that predators exerted a negative impact on their prey, whereas planktonic organisms exerted a positive impact on the majority of fish functional groups. The comparison of the model with other studies provided information that could inform the development of appropriate fisheries management guidelines for this area based on ecosystem properties.Keywords:Coral reef ecosystemEcopathEcosystem propertiesTernate IslandTrophic interaction

Abstract

Tabam waters are waters in Ternate City where the average population works as fishermen using gillnet fishing gear with the target fish being tuna (Eutynnus affinis) locally called Tongkol. Fishing activities in this area are generally carried out around FADs. Fishing that is carried out on an increasing basis and accompanied by an increase in gillnet fishing gear can endanger the sustainability of mackarel tuna/ tuna fish/komo tuna. Therefore, to maintain the sustainability of tuna fish resources in Tabam waters, an assessment of the biological status is needed which includes the structure of length, weight, circumference, growth patterns, and age groups. Establish guidelines for fishermen on the appropriate size of tuna to be harvested in order to preserve the sustainability of the tuna population. This research was conducted in December 2018-March 2019, using a sample size of 200 fish, using a survey method. The survey was conducted by examining the technical characteristics of gillnet fishing gear, FAD aids, and tuna catches. The results showed that the average fish caught was gilled with an isometric growth form and the average age group of tuna fish was around 21.7 cm, 17.2 cm, 18.9 cm, and 21.0 cm.Keywords:GillnetFADSAsessingKomoTunaTabam

Abstract

Macrozoobenthos are benthic animals commonly found in substrate-based ecosystems, such as mangrove forests. Their presence in mangrove ecosystems significantly influences the decomposition activities within the substrate or sediment layers. The aim of this study was to identify species composition, species density, community structure of macrozoobenthos, and their vertical distribution within sediments on mangrove ecosystem in Ternate City. The study was conducted from August to September 2021 using the line transect method, with macrozoobenthos samples collected through iron pipe corers. Data analysis included species density, species diversity, dominance index, evenness index, niche width, microhabitat niche overlap, and the relationship between macrozoobenthos density and depth. The results showed that the macrozoobenthos species composition consisted of two species (Uca spp. and Nereis spp.), with a total of 25 individuals. Species diversity within mangrove ecosystem was found to be low, with one dominant species and a relatively even distribution. The species with the broadest habitat niche was the worm (Nereis spp.), while significant microhabitat niche overlap occurred between the worm (Nereis spp.) and the crab (Uca spp.). Simple linear regression analysis indicated that substrate depth did not correlate with macrozoobenthos species density.Keywords:aquaticbenthoscoastalfaunaterrestrial
