Abstract

This study aimed to determine the size at first sexual maturity (L50) of Stolephorus indicus in the waters of North Gorontalo and to analyze its relationship with gonadal maturity through biological and statistical approaches. A total of 2,061 specimens were randomly collected from lift-net (bagan perahu) catches, after which each fish was measured for total length and dissected to identify its gonadal maturation stage. The proportion of mature individuals within each length class was then analyzed using a logistic curve to estimate the L50 value, representing the size at which 50% of the population reaches reproductive maturity. The results revealed a clear sigmoid pattern, indicating a positive correlation between body size and the proportion of mature fish; most individuals smaller than 4 cm were immature, while a significant increase in maturity occurred within the 4.5–6.5 cm size range. The estimated L50 of 5.42 cm suggests that a portion of the population is being harvested before reproducing, emphasizing the need for management measures such as implementing a minimum mesh size of 7 mm and establishing a minimum legal catch size of ≥6.5 cm to reduce juvenile exploitation and support the sustainable management of anchovy resources in North Gorontalo waters.

Abstract

Microplastic contamination is increasingly relevant in shrimp farming because plastic particles may originate from water, feed, equipment, packaging, and polystyrene-based foam materials commonly used throughout aquaculture supply chains. This study evaluated the effects of sublethal exposure to polystyrene microplastics (PS-MPs) in the rearing medium on growth performance and feed utilization efficiency of whiteleg shrimp (Litopenaeus vannamei). A completely randomized design was applied using four nominal concentrations of PS-MPs (0, 10, 20, and 30 mg/L), each with three replicates. PL-30 shrimp were reared for 45 days at a density of 20 individuals per 20-L container. The assessed parameters were absolute length growth, absolute weight growth, specific length growth rate, specific weight growth rate, feed conversion ratio (FCR), and feed utilization efficiency (EPP). Analysis of variance showed that all production parameters were significantly affected by treatment (p<0.001). The control consistently produced the highest values for growth-related traits and EPP, whereas the lowest values were generally observed at 30 mg/L. In contrast, FCR increased markedly in all exposed groups relative to the control. From the control to 30 mg/L, absolute length declined by 31.8%, absolute weight by 53.4%, specific weight growth by 54.0%, and EPP by 65.4%, while FCR increased by 141.4%. These findings indicate that PS microplastics in the culture medium are strongly associated with reduced production performance of whiteleg shrimp, especially through poorer growth and less efficient feed utilization.

Abstract

The Mahseer (Tor soro), an omnivore with herbivorous tendencies, requires a balanced combination of plant and animal-based nutrients. Lemna perpusilla shows high potential as a cost-effective, plant-based feed ingredient. This study aimed to determine the optimum combination of L. perpusilla meal and commercial feed to maximize the growth performance of T. soro. A completely randomized design (CRD) was employed with five treatments and three replications: P0 (100% L. perpusilla), P1 (75% L. perpusilla + 25% commercial feed), P2 (50% L. perpusilla + 50% commercial feed), P3 (25% L. perpusilla + 75% commercial feed), and P4 (100% commercial feed). The results revealed that P3 was the optimal formulation, showing the highest growth rates, protein efficiency ratio, and feed conversion ratio as follows: absolute weight growth of 0.66 ± 0.14 g, absolute length growth of 0.73 ± 0.06 cm, a protein efficiency ratio (PER) of 2.71 ± 0.65, a feed conversion ratio (FCR) of 1.24 ± 0.28, and a 100% survival rate. Water quality parameters remained within the tolerable range for T. soro culture. In conclusion, incorporating 25% L. perpusilla meal into commercial feed significantly supports growth performance, providing a clear and effective strategy for sustainable T. soro culture.

Abstract

This study aims to determine the effect of administering Artemia sp. feed at different doses on the survival, water quality, and growth of eel (Anguilla bicolor.). The study was conducted using an experimental method with a Completely Randomized Design (CRD), consisting of 3 treatments and 3 replications, analyzed using Analysis of Variance (ANOVA). A total of 14,400 eel juveniles with an initial average length of 4.98 ± 0.01 cm and an initial average weight of 0.138 ± 0.001 g were used as test animals. The treatments applied were different doses of Artemia sp. feed: treatment A (5%), treatment B (10%), and treatment C (15%) of the biomass weight for each treatment. The results showed that feeding Artemia sp. at different doses had no significant effect on survival rate (SR), water quality, or growth, but it significantly influenced the optimization of the water quality of the rearing media. At the end of the study, the survival rates for each treatment were: treatment A 98%, treatment B 99%, and treatment C 98%. The average weight gain in treatment A (5% dose) was 0.875 ± 1.421 g, with an average length increase of 0.237 ± 0.013 cm. Treatment B (10% dose) resulted in an average weight gain of 0.353 ± 0.034 g and an average length increase of 0.156 ± 0.002 cm. Treatment C (15% dose) resulted in an average weight gain of 0.167 ± 0.033 g and an average length increase of 0.243 ± 0.012 cm. Water quality parameters in all treatments remained within optimum conditions, with pH 7.49, temperature 24.0°C, and dissolved oxygen (DO) 6.2 mg/l, which supported the experimental treatments. Keywords : Anguilla bicolor, feed dose, Artemia sp, growth, survival rate.
