Abstract

Crab is one of the coastal fisheries resources that has high economic value and has been intensively utilized. This study aims to analyze the size of the carapace width and weight of the S. serrata crab. The research was conducted using the survey method, through measurement at the crab landing and marketing site. The results showed that the carapace width of male mud crabs ranged from 59.1-149.3 mm (87.35 ± 12.36 mm), with weights ranging from 30.0-560 g (121.68 ± 46.11 g). Female mud crabs had carapace widths ranging from 64.0-172 mm (88.16 ± 14.24 mm), with weights ranging from 40.0-790 g (128.14 ± 64.20 g). The growth pattern of male and female mud crabs is negative allometric, with carapace width increasing faster than crab weight. Crabs that meet the size that can be caught based on carapace width are 13 crabs (2.32%) and based on weight are 118 crabs (21.03%). The crabs caught predominantly did not meet the catchable size.Keywords: Carapace Width; Catchable Size; Growth Pattern of Scylla serrata; Weight

Abstract

This study aims to analyze the biological aspects of the kejen shark (Carcharinus falciformis) landed at the Paotere Fish Landing Base (PPI), Makassar, including its size structure and growth pattern as a basis for information on sustainable resource management. The study was conducted in January–March 2025 using a field survey method. Kejen shark samples were obtained from fishermen's catches landed at the Paotere PPI. Each individual caught was measured for total length (cm) and body weight (kg). Data were analyzed to determine the size distribution and length–weight relationship using regression analysis. The results showed that the total length of male kejen sharks ranged from 65–145 cmTL and females 65–155 cmTL, with body weights of 1–13 kg and 1–25 kg, respectively. The length–weight relationship produced a regression equation with a coefficient of determination (R²) of 0.9061 and a growth coefficient (b) of 3.3188, indicating a positive allometric growth pattern. The size structure of the fish caught indicates that the catch encompasses a wide range of sizes, including sexually immature individuals. This situation has the potential to reduce the wild population of the kingfisher, given its relatively slow growth and reproduction rates, necessitating more selective and sustainable fishing management.

Abstract

Integrated aquaculture or IMTA is a cultivation method that involves several communities with different trophic levels, in terms of the utilization of food sources (energy) in the waters. To determine the effect of species combinations on snapper growth in integrated cultivation of controlled recirculation system and To determine the effect of species combination on snapper survival in integrated cultivation of controlled recirculation system, the research method used was Complete Random Design (RAL) with 4 treatments and 3 replications and used ANOVA (Analysis Of Variance) data. The results showed that the survival of white snapper during 5 weeks of maintenance showed that the cultivation system had a significant effect on the ability of fish to survive, with the highest value in P4 treatment (IMTA) of 85.0% and lowest in P1 treatment (monoculture) of 43.80%, while P2 and P3 treatment reached 54.20% and 60.40% respectively. This pattern indicates that the integration of snapper with green shellfish and sea grapes in the IMTA system is able to create a more stable maintenance environment and support fish survival through the use of feed waste and feces as a source of nutrition for other organisms, thereby reducing the accumulation of toxic materials such as ammonia that have the potential to trigger stress and death. The results of ANOVA's analysis, which showed a significant influence of species combinations on synthesizers, as well as Tukey's follow-up tests, which confirmed the very real difference between P4 and other treatments, reinforced that integrated aquaculture approaches are more effective than monocultures or simple polycultures in improving the survival of white snapper in a closed recirculation system

Abstract

Increasing the productivity of aquaculture must be supported by feed input; however, in addition to being expensive, this input can produce nutrient waste. Therefore, finding inexpensive alternative forms of feed with environmentally friendly cultivation practices is important to do simultaneously. This study aimed to determine the effect of variations in the form of maggot feed on the Nutrient Reduction Efficiency (NRE) of freshwater clams (Pilsbryoconcha exilis) in an integrated multitrophic aquaculture (IMTA) system. This 28 day experiment used a Completely Randomized Design (CRD) with four types of feed treatments (live maggots, dried maggots, supplemented maggots, and commercial feed (control). A total of 10 individuals of freshwater clams combined with 10 tilapia fish and freshwater lobsters respectively, as well as 4 clumps of rice were floated in a rearing tank with a volume of 50 L of fresh water. The results of analysis of variance showed that variation in feed had a significant effect (P<0.05) on the NRE of ammonia (NH3), nitrate (NO3), phosphate (PO4) by freshwater clams (Pilsbryoconcha exilis). Tukey HSD test results indicated that the highest NRE of ammonia (NH3) in live maggots feed was significantly different (P<0.05) from dried maggot feed and supplemented maggots, but not significantly different (P>0.05) from commercial feed. NRE nitrate (NO3) was significantly different in each treatment. Meanwhile, the highest NRE phosphate (PO4) in live maggots feed was not significantly different (P>0.05) from dried maggots, but was significantly different (P<0.05) from supplemented maggots and commercial feed.

Abstract

Glossogobius matanensis is one of the endemic fish species found only in Lake Towuti, South Sulawesi. Its limited population and environmental pressures make it necessary to conserve efforts through a domestication approach. This study aims to analyze the condition factor of G. matanensis fish as an indicator of health and biological readiness in the context of domestication. Sampling was carried out at several points in the waters of Lake Towuti using the purposive sampling method. The observed parameters included total length, body weight, and condition factor (K) which were calculated using the King formula. The results showed that the value of the condition factor ranged from 1.00–1.05 which indicated that the fish was in good physiological condition. The variation in K-values also reflects differences in habitat quality and availability of natural feed in each location. These findings provide an important basis for the development of early aquaculture technologies and support long-term conservation programs for this endemic species. The domestication of G. matanensis is seen as an adaptive strategy to maintain the sustainability of local genetic resources amid changes in the ecosystem of Lake Towuti

Abstract

The two main sectors, agriculture and fisheries, play an important role in ensuring food security and community nutrition. However, limited land, water resources, and energy are problems that these two sectors often face. Research on FCR on a GIS-based floating-bed model IAA system can provide important information on how to improve the efficiency and productivity of the system. This study aims to determine the effect of the extractive species placement model on the Feed Conversion Ratio (FCR) of tilapia (Oreochromis niloticus) in the Integrated Agriculture Aquaculture (IAA) system of the GIS-based floating-bed model. The study used a Complete Random Design (RAL) with three treatments and three replicates. The treatments tested were Treatment A (no floating-bed transfer during maintenance), Treatment B (10-day interval transfer), and Treatment C (20-day interval transfer). The research was carried out for 90 days in the pool of the People's Hatchery Unit (UPR) Sipurennu, Citta District, Soppeng Regency. The main parameter observed is the FCR value. The results showed that the FCR values in Treatment A, B, and C were 1.03, 1.09, and 1.08, respectively. ANOVA analysis showed no significant difference between treatments (F=0.389, Sig.=0.694). The conclusions of the study showed that the effect of the extractive species placement model on the Feed Conversion Ratio (FCR) of tilapia (Oreochromis niloticus) in the Integrated Agriculture Aquaculture (IAA) system of the GIS-based floating-bed model effectively resulted in a low FCR value in the range of 1.03-1.09, with the lowest value at treatment A (without floating-bed transfer during maintenance).

Abstract

This study aimed to identify potential fishing grounds for the blue octopus (Octopus cyanea) around Barrang Caddi Island, Makassar City, by integrating field observations with remote sensing-based oceanographic parameters. A quantitative descriptive survey was employed by accompanying local fishermen during 21 fishing trips using handline (handline hook) gear. Geographic coordinates of fishing locations were recorded using a Global Positioning System (GPS), while satellite-derived sea surface temperature (SST), salinity, and chlorophyll-a concentration were obtained from Aqua MODIS and HYCOM datasets. Spatial analysis was performed using Geographic Information Systems (GIS) to delineate potential fishing zones based on the integration of catch distribution and environmental variables. The results revealed that potential fishing grounds were predominantly located in shallow coral reef habitats surrounding Barrang Lompo and Barrang Caddi Islands. Sea surface temperature averaged 29.24°C, salinity reached 30.8 PSU, and chlorophyll-a concentration ranged from 0.6 to 0.8 mg m⁻³, indicating environmentally favorable conditions for Octopus cyanea. Moderate-potential fishing zones occupied the largest spatial extent, whereas high-potential areas were concentrated near structurally complex coral reef ecosystems. These findings demonstrate that remote sensing provides an effective approach for identifying productive octopus fishing grounds and can support sustainable fisheries management, improve fishing efficiency, and provide scientific information for spatial planning and resource conservation in the Spermonde Archipelago.

Abstract

Integrated Multi-Trophic Aquaculture (IMTA) has emerged as an environmentally sustainable aquaculture approach by integrating organisms from different trophic levels to improve nutrient recycling efficiency. This study evaluated the effectiveness of various IMTA species combinations in reducing Total Ammonia Nitrogen (TAN), Dissolved Inorganic Nitrogen (DIN), and Dissolved Inorganic Phosphate (DIP) within marine culture systems. A completely randomized design with four treatments and three replications was employed, comprising P1 (Lates calcarifer), P2 (Lates calcarifer + Perna viridis), P3 (Lates calcarifer + Caulerpa lentillifera), and P4 (Lates calcarifer + Perna viridis + Caulerpa lentillifera). Water samples were collected every 15 days over a 45-day culture period and analyzed using UV–Visible spectrophotometry. Nutrient reduction efficiency was calculated for each treatment, while one-way Analysis of Variance (ANOVA) followed by Tukey's post hoc test was applied to determine significant differences among treatments. The results demonstrated that integrated culture systems consistently reduced nutrient accumulation more effectively than monoculture. The complete IMTA treatment (P4) exhibited the greatest capacity to regulate TAN, DIN, and DIP concentrations through complementary nutrient uptake by macroalgae and filtration by bivalves. ANOVA confirmed significant treatment effects on TAN (F = 6.24, p = 0.021), DIN (F = 5.87, p = 0.016), and DIP (F = 5.21, p = 0.021). These findings demonstrate that integrating Lates calcarifer, Perna viridis, and Caulerpa lentillifera substantially enhances nutrient recycling efficiency, improves water quality, and provides an ecologically sustainable strategy for tropical marine aquaculture.

Abstract

The existence of microplastics will cause the environment to be disturbed because of their microscopic size so organisms very easily swallow them. This research aims to analyze the microplastic content in sediment based on type, color, shape, size, and type of microplastic polymer. The research method used is quantitative with a survey approach. Sampling was conducted using transects stretched along the coastline for 25m into the sea. Observations at each location consisted of 3 sub transects with 2 repetitions. The research results show that the forms of microplastic found in North Galesong waters are in the form of lines and fragments. A total of 2 particles are in the form of fragments and 41 are in the form of lines. Analysis of the color of the microplastics found 27 particles blue, 7 particles transparent, 8 particles red, and 1 particle green. The size of microplastics at station 1 was dominated by line shapes with sizes ranging from 0.084-0.854 mm and those in fragment form ranging from 0.222 mm, at station 2 the size of line shape microplastics ranged from 0.069-0.963 mm and fragments 0.092 mm, and at station 3 the microplastic particles were in the form of lines range from 0.063-0.693 mm. The total abundance of microplastics in North Galesong waters was 0.43 particles/gr, namely at station 1 as much as 0.11 particles/gr, station 2 as much as 0.11 particles/gr, and station 3 as much as 0.21 particles/gr. The types of polymers found at each station are polyester polymer, PAN film, isotactic polypropylene, powdered cellulose, cellulose, and cellophane.
