Abstract

Kubutambahan Village is one of the villages in Kubutambahan Subdistrict, Buleleng Regency with the main catch fishery potential of Mackerel scad and several other species of fish. The fishing gear used by fishermen is dominated by mini purse seine. The purpose of this research was to determine the types of fish caught and the composition of fish catches. This research was conducted from September 2021 until October 2021. The data were obtained by direct observation in the field. Fish samples were taken using simple random sampling. The results showed that there were 20 species of fish, grouped into 5 orders, 9 families and 16 genera. The composition of the catches of fishermen using mini purse seine is dominated by Mackerel scad at 48.4% and the lowest is Hound Needlefish at 0.001% of overall catch.

Abstract

The relationship between length type, length-weight relationship and condition factors is an initial approach to fisheries management. Research related to that issue on spotted barb (Barbodes binotatus) in four lake ecosystems in Bali has never been published. This study aims to reveals information related to the relationship of length character, growth patterns and conditions of B. binotatus in four lake ecosystems in Bali. Fish sampling was carried out from August 2017 to July 2018 at Tamblingan Lake, Buyan Lake, Beratan Lake and Batur Lake which were carried out alternately. The results of this study revealed that the total length (TL), fork length (FL) and standard length (SL), each type of measurement can be used to estimate the weight of B. binotatus, but standard length was the most suitable type of measurement in estimating weights. This fish species has a positive allometric growth pattern (b>3) with an estimated condition that is in good condition.

Abstract

The diversity of ichthyofauna is an important aspect that can be used to presume the aquatic environmental conditions. Therefore, this study aims to determine the diversity of ichthyofauna in Taman Hutan Raya (TAHURA) Ngurah Rai, Bali during the eastern season and transitional II season. The sample was collected from July 2022 – October 2022 using an experimental gill net. During the sampling period of this study, 413 fishes were caught, representing 18 different species from 17 genera, 14 families, and 12 orders. Based on the results of the analysis, the highest diversity value was found in the waters of Jimbaran, then the waters of Kampung Kepiting, while Serangan waters has the lowest diversity value (H’<1). The lowest uniformity index was found in the waters of Serangan because it is dominated by only one fish species, namely Ambassis macracanthus (Seriding Fish), while in the waters of Kampung Kepiting and Jimbaran, the uniformity is quite even. The highest dominance index was found in the waters of Serangan, while other water areas has no dominating species. The species composition found at all stations varied considerably, but the results of the IUCN status showed that most of the fishes were still in the category of data deficient and not evaluated. The highest abundance was found in the waters of Serangan. The water quality parameters of TAHURA Ngurah Rai showed that not all aspects are in accordance with quality standards for marine life.

Abstract

The growth aspect is important in determining fish well-being in an area. However, research on the growth aspect of Ambassis macracanthus Bleeker, 1849, in Ngurah Rai Forest Park has never been conducted This study aims to determine the length-weight relationship and condition factor of A. macracanthus as well as to evaluate the water condition in Ngurah Rai Forest Park, Benoa Bay during the east season. The sample was collected applying descriptive and quantitative methods, whilst the purposive sampling method was used to take the samples from three stations using Bubu and experimental gill net. During the sampling collection process, 304 fish individuals were caught by the experimental gill net at station 1 (Serangan waters). Based on the analysis between the length and weight relationship of A. macracanthus, the equation of W=0,024L2.38, where from this equation, the value of b = 2.38 is obtained. Through the T-test, the value of b < 3 showed a negative allometric growth pattern; namely, the growth in length is more dominant than the increase in weight. The average relative condition factor increased monthly, with the highest value of 1.37 in August. However, the value of the relative condition factor indicates that the fish in Tahura waters are thin (Kn < 2). In general, the temperature and dissolved oxygen of Ngurah Rai Forest Park waters are not following quality standards.

Abstract

Midas cichlid fish (Amphilophus citrinellus) is often referred to as a pest fish because it is a fish that can only prey but does not produce sufficient economic value, because it reproduces very quickly. This research aims to determine the length-weight relationship, growth patterns and condition of Midas cichlid fish as well as the water conditions of Lake Batur. The research was carried out using quantitative descriptive methods, with a purposive sampling method for sampling. The sampling locations were at three stations. The fishing gear used is gill nets. The total number of fish caught during data collection was 287 individuals. Based on the results of the analysis of the length-weight relationship of midas cichlid fish (Amphilophus citrinellus) in Lake Batur, the equation W=0.0215L2.92 was obtained, where from this equation the value b = 2.92 was obtained. The t test was carried out and it was found that the b value was <3 so it could be concluded that the growth pattern was negative allometric. The relative condition (Kn) of male and female Midas cichlid fish in Lake Batur is in good condition (1.01), with a less flattened body shape (fusiform). The condition of the water parameters in Lake Batur during the research was classified as good and stable for the survival of aquatic biota, one of which was the Midas cichlid fish with a pH value of 7.1-7.5; DO 5.3-6.5 mg/L; Temperature 27.8-29.6°C and brightness 1.5-1.9 m.
