Ovarian development of Notopterus notopterus (Pallas, 1769) injected with human chorionic gonadotropin

 

Abstract. 

The bronze featherback, Notopterus notopterus (Pallas, 1769), is a wild species that has not been domesticated. Wild species reared in aquaculture tanks tend to experience disturbances in their reproductive systems. The purpose of this study was to determine changes in the development of N. notopterus ovaries after being injected with human chorionic gonadotropin (hCG). This study was a laboratory experiment. The experiment used a completely randomized design with four treatments and three replications of hCG dosage (0, 150, 200, and 250 IU kg^-1 of fish). Administration of hCG was through intramuscular injection. Each fish was injected only once. On the 7th and 14th days after injection, blood was collected from N. notopterus, and then the fish were dissected for liver and ovary collection. The results showed that the administration of hCG stimulated the development of N. notopterus ovaries. The stage of ovarian maturity in N. notopterus increased. This is the first study to induce ovarian maturation in N. notopterus using hCG. The results of this study provide valuable information for future studies on the breeding programs of N. notopterus.

Effects of Purwoceng Plant (Pimpinella alpine) Extract on Masculinization of Guppy (Poecilia reticulata)

 ABSTRACT

In the context of guppies (Poecilia reticulata), male fish are considered more attractive and valuable. The majority of mono-sex production in male fish employs the use of 17α-methyltestosterone, an expensive hormone with limited supply. It is therefore necessary to explore the potential of natural ingredients as an alternative replacement, such as purwoceng (Pimpinella alpina). The objective of this study was to determine the optimal immersion duration for the masculinization of P. reticulata. This study employed a completely randomized design with four treatments of immersion duration (0, 8, 10, and 12 hours), with three replications allocated to each treatment. Following immersion, the guppy larvae were reared for a period of 45 days and fed with Daphnia, sp and Artemia cysts. The sex of each fish was determined via surgical procedure at the conclusion of the larval rearing period. The findings revealed that the duration of larval immersion in P. alpina extract had a notable impact (P < 0.05) on the proportion of male fish. In this study, the 10-hour immersion treatment yielded the highest number of male P. reticulata, at 83.33%. The results of this study are highly valuable for the application of sex reversal techniques using phytosterol as a replacement for synthetic hormones.

Morphometric-meristic characters of Sumatran featherback (Chitala hypselonotus, Bleeker 1852) from Kelekar River, South Sumatra, Indonesia

 Abstract

The Sumatran featherback (Chitala hypselonotus, Bleeker 1852) is an endemic freshwater fish species native to the island of Sumatra in Indonesia. The objective of this study was to measure and calculate the morphometric-meristic characters of C. hypselonotus. The study utilized a total of ten specimens, collected between July and September 2024, from the Kelekar River in Indonesia. The morphometric and meristic characters of C. hypselonotus were measured at the Fisheries Laboratory, Department of Fisheries, Faculty of Agriculture, Universitas Sriwijaya, Indonesia. The results demonstrated that the total length of C. hypselonotus samples ranged from 340 to 500 cm, with a standard length ranging from 310 to 470 cm. Additionally, the body weight of the specimens ranged from 276 to 1066 g, with a proportion of standard length to total length of 94.16% and a head length to standard length ratio of 21.28%. The number of rays on the dorsal fin is 9 (D. 9), the pectoral fin has between 12 and 15 rays (P. 12-15), the ventral fin has between 2 and 3 rays (V. 2-3), and the anal fin is fused to the caudal fin, with a range of 118 to 131 rays (A-C. 118-131). The findings of our present study may prove useful to students, fisheries biologists, and taxonomists in the future, facilitating the correct identification and classification of C. hypselonotus. It is recommended that further studies be conducted on the morphometric-meristic and other biometric parameters of the threatened and commercially important fish C. hypselonotus, to enable the management and conservation of populations in natural water bodies.

Morphometric-meristic characters and reproductive biology of seluang fish (Rasbora sumatrana, Bleeker 1852) from the Ogan River, South Sumatra, Indonesia

 Abstract: 

The seluang fish (Rasbora sumatrana, Bleeker 1852) is one of Indonesia’s native freshwater fish species with high economic value and potential for aquaculture. The fish is consumed by the local community, both fresh and in processed form. The objective of this study was to analyze the morphometric and meristic characteristics, as well as certain aspects of the reproductive biology, of both male and female seluang fish. The specimens were obtained from the Ogan River in Tanjung Raja, Ogan Ilir Regency. A total of 150 fish samples were utilized for the study. The sample comprised 99 males with a total length of 3.5–7.3 cm and a total weight of 0.65–2.79 g, and 51 females with a total length of 1.5–6.7 cm and a total weight of 0.44–4 g. A total of 10 morphometric characteristics, 5 meristic characteristics, and 7 reproductive aspects were subjected to analysis. The results indicated that there were differences in the morphometric characteristics between the male and female fish, specifically in terms of head width, body depth, caudal fin length, dorsal fin length, and pre-dorsal length. No significant differences were observed in the meristic characteristics between the male and female specimens. The gonadosomatic index of males ranged from 0.22 to 23.63, while that of females ranged from 0.70 to 29.72. The hepatosomatic index of males ranged from 0.07 to 4.49, while that of females ranged from 0.04 to 1.66. The observed sex ratio was 0.786:1. The fecundity of the specimens ranged from 202 to 2915 eggs, with an egg diameter that varied between 0.8 and 1.12 mm. The gonadal maturation stage for both males and females was identified as II-V. The water quality at the sampling location was found to be 24.8–28.5 ℃, with a pH range of 5.5–6.4 and a dissolved oxygen concentration of 4.9–6.2 mg/L. In conclusion, there are differences in the morphometric characteristics between male and female fish, but no differences in the meristic characteristics. The gonadosomatic index and the hepatosomatic index of the female fish are higher than those of the male fish.

Length-weight relationship, condition factor, and environmental parameters of Puntigrus tetrazona from Kelekar River, Ogan Ilir, South Sumatra, Indonesia

 Abstract 

Length-weight relationships, condition factors, and environmental parameters are important parts of fisheries management. The freshwater fish species Puntigrus tetrazona is endemic to Indonesia. The objective of this study was to determine the length-weight relationship, condition factors, and environmental parameters of P. tetrazona from the Kelekar River in South Sumatra. A total of 121 P. tetrazona were used in this study. The results showed that the length-weight relationship of P. tetrazona was negative allometric, with the regression equation W = 0.0656 x L1.9002 (R2 =0.5603). The P. tetrazona population was in good condition, as indicated by a condition factor value of 1.00. Environmental parameters including water temperature, pH, dissolved oxygen, electrical conductivity and oxidation reduction potential are suitable for the life of P. tetrazona. The findings of this study will be of significant value in informing the management of P. tetrazona resources.
