Abstract

Diopatra claparedii Grube, 1878, is a common polychaete species that occurs in Southeast Asian countries, including Malaysia, Singapore, Thailand, and the Philippines. However, the occurrence of this species in Indonesia has never been recorded. In the present study, we identified the presence of D. claparedii in the eastern part of the Segara Anakan Lagoon in Cilacap, Central Java Province. Thespecies is characterized as having distinct pectinate chaetae with funnel-like combs. The worms, like in some other Asian countries, are commercially exploited for use as fishing bait. The distributional map of this species is provided in this article.

Abstract

Plastic is a widely used material with several toxic components, such as free radicals. HDPE plastic is considered safer but requires more attention due to increased usage. Exogen antioxidant is needed to neutralize free radicals. This research aimed to evaluate the effect of natural antioxidants on the performance of erythrocytes, leucocytes, and hemoglobin levels of pregnant mice exposed to plastic compounds. The study used a completely randomized design with six groups and four replicates each. Those groups were aquadest control, plastic chemical compounds (PCC) control, PCC + carrot juice, PCC + orange juice, PCC + purple sweet potato juice, and PCC + mung bean sprouts juice. The PCC was obtained from boiling HDPE plastic, while natural antioxidant juice was from pure sources. Pregnant mice were treated with 0.25 ml of each orally for 21 days, starting from the first gestational day. Blood was collected from a caudal vein. Erythrocytes and leucocytes were counted using a hemocytometer, and Hb levels were measured by the Sahli method. Blood cell morphology was assessed using Giemsa-stained blood smears. Statistical data were analyzed by one-way ANOVA using GraphPad Prism ver.10.0 software, while morphology data were analyzed descriptively. The results showed that PCC and natural antioxidants did not impact the number of erythrocytes, leucocytes, cell morphology, and Hb levels of pregnant mice. However, natural antioxidants may stabilize the erythrocyte total and Hb levels after the treatments are completed.

Abstract

Diopatra claparedii Grube, 1878, is a tubicolous polychaete species widely used as fishing bait by local anglers in Cilacap, Central Java, Indonesia. Little is known about its biological characteristics despite its ecological and economic importance. This study aimed to examine the survival rate, growth, metabolic rate, and osmoregulatory capacity of D. claparedii under different salinity conditions. The experiment was conducted using plastic containers (20 × 30 × 25 cm) filled with a muddy substrate and water at four salinity levels: 10, 15, 20, and 25 ppt, with each treatment replicated five times. The results showed that the survival rate of D. claparedii ranged from 87% to 93%, while its growth varied between 0.17 and 0.58 g. The metabolic rate, measured in terms of oxygen consumption, ranged from 0.201 to 0.467 mg·g-¹·h-¹. The  osmoregulatory capacity of the worms varied between 1.26 and 1.54 mOsm·kg-¹ solvent. Statistical analysis indicated that salinity did not significantly affect survival (p> 0.05). However, it significantly influenced growth, metabolic rate, and osmoregulatory capacity (p< 0.05). The results suggested that a 15–25 ppt salinity range was more favorable for the species, with 20 ppt being the most optimal level for its maintenance and growth. This study highlights the potential for cultivating D. claparedii under controlled conditions, providing a sustainable alternative to wild harvesting. As polychaete farming has been successfully implemented in several countries, similar efforts could be applied in Indonesia to support local fisheries while conserving natural populations.

Abstract

Studies on morphology, growth, and reproduction have been carried out on wild Javaen barb, but there was no information on its digestive capacity; therefore, the research was conducted to determine protease and amylase activities in the digestive tract. This study used a total of 50 barbs with body weights between 13.56 -128.93g / fish. The measurement of enzyme activity was carried out using the spectrophotometer method. The results showed that differences in fish size resulted in differences in protease activity, but not for amylase. Fish with a small size have a higher protease activity than fish with a larger size. The protease activity did not differ between pH 6.9 to 10.0 but was higher than pH 12.5. Protease activity also did not vary between the anterior and posterior intestine and between 30-50°C. Amylase activity also found no difference between the anterior and posterior intestine, but there was a difference in activity between temperatures of 30-50°C. In conclusion, protease activity occurs in a neutral to alkaline environment, and there were differences in protease activity between different body sizes but not between intestinal segments. Amylase activity occurs throughout the intestine and decreases at temperatures of 50°C.

Abstract

Many studies have been conducted on the feeding frequency in fish, but there is no information on R. lateristriata. Therefore, this study aimed to determine yellow rasbora growth performance, feed efficiency, and digestive enzyme activity at different feeding frequencies. This research was conducted experimentally with four treatments and three replications. The treatments include: P1 fish were fed two times/day; P2 fish were fed three times/day; P3 fish were fed four times/day; and P4 fish were fed five times/day. In this experiment, 420 two-month-old yellow rasboras were used. The experimental results showed that body weight gain, RGR, SGR, CF, FCR, PER, body lipid & protein levels, protein and lipid retention, protease, and amylase activity were not significantly different (p>0.05) between different feeding frequencies. However, lipase and alkaline phosphatase activities differed significantly among the different feeding frequencies. Growth performance, feed efficiency, protease activity, and yellow rasbora amylase are not affected by feeding frequency between two to five times a day. Still, the highest lipase and alkaline phosphatase activity were achieved at the feeding frequency four times a day, but no effect on growth. So, feeding twice a day is considered quite efficient for the culture of yellow rasbora. The results of this study can contribute to the development of fish farming, especially the yellow rasbora, in the future.
