Abstract

A study on the cultivation of tilapia (Oreochromis niloticus) in brackish water using co-culture systems (polyculture, IMTA-non paddy, and IMTA-paddy) and monoculture systems was evaluated on a laboratory scale to determine its growth. Several species of aquatic animals and paddy (floating system) were combined with tilapia reared in plastic tanks for 28 days. Tilapia were fed four times a day at a feeding rate of 10% of biomass. The highest specific growth rate (SGR), IMTA-paddy system (4.24±0.08% day-1), polyculture (4.13±0.06% day-1), IMTA-non paddy (3.84±0.23% day-1), and monoculture (3.80±0.05% day-1). The same pattern was found in the addition of morphometric characteristics (AMC). Total length, standard length, body length, and height respectively from the highest IMTA-paddy system (2.49±0.12; 2.14±0.12; 1.81±0.14; 0.49±0.19 g), polyculture (2.32±0.16; 2.07±0.09; 1.72±0.11; 0.41±0.11 g), IMTA-non paddy (2.18±0.12; 1.78±0.15; 1.62±0.15; 0.33±0.14 g), and monoculture (2.02±0,09 1.67±0.08; 1.57±0.08; 0.30±0.10 g). Analysis of variance indicated that SGR and AMC of tilapia were significantly influenced by the culture system (P<0.05). The SGR and AMC in the IMTA-paddy system were significantly higher (P<0.05) than those in the monoculture and IMTA-non-paddy systems, but not significantly different (P>0.05) from those in the polyculture system. In general, tilapia growth was higher in co-culture systems than in monoculture systems in brackish water, which led to the diversification of aquaculture production.Keywords: Brackish water; Co-culture; Growth; Nile tilapia; Rice.

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

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.

Abstract

The nutritional potential of copepods as live feed for larvae warrants further exploration, particularly for juvenile and adult shrimp. However, their small size presents a challenge, as larger shrimp may struggle to capture such small prey. A nutrient-based formulation approach was adopted by supplementing Oithona sp. copepod meal into vannamei shrimp (Litopenaeus vannamei) feed, and its effects on survival and growth were evaluated. A 35-day experiment was conducted in aquariums (20×20×30 cm) with an 8-liter water volume. The experimental feed was prepared by coating it with copepod meal. Four supplementation levels, each with three replicates, were tested: 0, 1, 2, and 3 g per 100 g of feed. Vannamei shrimp with an initial weight of 2.15±0.03 g and a stocking density of 16 individuals per aquarium were fed three times a day to satiation. Although the differences were not statistically significant, the survival rate of shrimp fed with supplemented diets (all 100±0.00%) was higher than that of the non-supplemented group (97.9±3.6%). In terms of growth, Absolute Weight Gain (AWG) and Specific Growth Rate (SGR) were significantly higher in the 3 g (5.27±0.02 g and 3.53±0.01% day-1), 2 g (5.13±0.08 g and 3.51±0.06% day-1), and 1 g group (4.88±0.10 g and 3.36±0.07% day-1) compared to the non-supplemented group (2.97±0.13 g and 2.48±0.11% day-1). In conclusion, the supplementation of copepod meal effectively enhanced the survival and growth of vannamei shrimp. The 3 g dose is the best dose that promotes the highest growth and survival.

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

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.
