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

ABSTRACT. The critical problems in eel cultivation are slow growth due to low digestibility and high feed conversion. This shows the need to understand the biochemical composition of eel to obtain information about the physiological condition, energetic adaptation, habits, nutritional value, and industrial uses. Nutritional data are also essential to develop a suitable processing method that enables eel to be consumed throughout the year while respecting state-imposed limitations to protect the species. Despite the significant contribution, there has been no data about the biochemical composition and the digestive enzyme activity of eel species such as Anguilla bicolor McClelland 1844, during the reproductive phase. Therefore, this study aimed to evaluate the biochemical composition of A. bicolor McClelland and the digestive enzyme activity during the reproductive phase. The experiment was conducted through a survey on eels in the reproductive phase with an average weight and length of yellow (106.00 ± 38.1 g and 42.00± 5.78 cm) and silver eel (362.89 ± 88.93 g and 59.86 ± 7.39 cm) respectively. The results showed that Nitrogen Free Extract (NFE) did not substantially alter between different phases, while the percent protein, lipid, ash, and fiber had significant variation (p<0.05). The activity of pepsin differed in various phases (p<0.05), while the activity of trypsin, amylase, and lipase of A. bicolor did not vary (p>0.05). The yellow eel had a higher body protein composition and pepsin activity than the silver eel, although the biochemical composition and other enzyme activities were similar. In summary, the biochemical compositions, and digestive enzymes of A. bicolor varied depending on their phases. Moreover, further studies were recommended to understand the biochemical composition of A. bicolor and digestive enzyme activity during the reproductive phase.

Abstract

Barred loach is wild fish in which there is no information related to its enzymatic digestive capacity yet. Therefore research on this subject needs to be conducted.  The spectrophotometry method was used to study protease, lipase, and amylase activities in barred loach. The study used 89 fish with an average weight of 3.61 ± 0.26g, and 1.68 ± 0.21g.  The results showed that pH 7.0 was the highest protease activity. Similarly, lipase activity found  between pH 7.0 and pH 8.1. Still, the amylase activity found to be high at pH 8.1. Protease activity also found to be high in the posterior intestine than in the hepato-pancreas and anterior intestine. Lipase and amylase activities did not found differences between hepato-pancreas, anterior intestine, and posterior intestine. In conclusion, the protease, lipase, and amylase activities of barred loach found along the gastrointestinal tract in both large and small fish, which shows that barred loach can digest protein, fat, and carbohydrates in diets better.

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.
