Abstract

Tor tambroides, T. tambra, T. douronensis, and T. soro are native fish species to Indonesia with their natural habitat generally being upstream of rivers in hilly areas with clear water and strong currents. Information of the structure and function of appendicular osteology is necessary to understand how fish accelerate and maintain body balance in the water. This study used 5 samples per fish species obtained from Tor fishermen around the habitat of these fish. The results of the comparison showed morphological differences between the appendicular structure of Tor species, consisting structure of the pinnae pectoralis, pinnae pelvicalis, pinnae dorsalis, pinnae analis, and pinnae caudalis. The highest variation was found in the pinnae caudalis. The pointed shape of the pinnae caudalis with long fin rays indicates that the Tor species is capable to swim at a high speeds.Keywords:ossa appendiculareTor douronensisTor tambraTor tambroidesTor soro

Abstract

This study aimed to determine the relationship between age and testicular morphometrics in lovebird (Agapornis fischeri), as well as the relationship between age and the gonadosomatic index (GSI) of the testes, and to evaluate the effect of body weight on testicular weight in determining the onset of puberty. This study used 30 lovebirds divided into three age groups: 4, 5, and 6 months, with ten birds in each group. The variables measured were testicular length, width, volume, weight and body weight. Data were analyzed using correlation analysis, simple linier regression, and paired sample t-test. The results showed a positive relationship between age and testicular length, width and volume. The GSI values of lovebirds aged 4, 5 and 6 months were 0.015 ± 0.002, 0.058 ± 0.011, and 0.400 ± 0.067, respectively, indicating an increase with age. The significance coefficient at 4 months of age was 0.000 (p <0.05), indicating that body weight had a significant influence on testicular weight at this age. In contrast, lovebirds aged 5 and 6 months had significance coefficients of 0.079 and 0.089 (p >0.05), indicating that testicular weight was not significantly influenced by body weight at these ages. It can be concluded that lovebirds at 6 months of age are likely to have reached puberty.

Abstract

The fish diversity within the Leuser Ecosystem Area (LEA), particularly in the Sikundur River, plays a crucial role in maintaining the balance of freshwater ecosystems. However, the populations of Mahseer (Tor tambroides and Neolissochilus soro) in this region are under threat due to habitat alteration and intensive exploitation. This study aims to examine the composition structure and size distribution of these two Mahseer species in the Sikundur River. Data collection was conducted at three stations representing different ecological settings: a residential area (Station 1), an agricultural plantation (Station 2), and a natural forest (Station 3). The study was carried out across two seasonal periods, dry season (April–September 2023) and rainy season (October–March 2024). Fish were sampled using cast nets, gillnets, and handlines with the assistance of local fishers, during both morning and evening sessions. Samples were analyzed descriptively and presented in tables and graphs. Results showed that Station 3, located in a natural forest, had the highest proportion of juvenile and adult Mahseer with the largest sizes and weights, particularly during the dry season. Station 1 was dominated by smaller juveniles, especially in the rainy season. Station 2 displayed variable patterns. Seasonal and ecological differences significantly influenced Mahseer population structure and growth dynamics.
