Abstract

The Kapuas River is one of the main rivers that supports potential fish resources in West Kalimantan. However, currently the development of the Kapuas River watershed is starting to appear to be influenced by ecological pressure from the agricultural and industrial sectors which has an impact on decreasing the potential of several target fish species. The aim of this research is to determine the habitat preferences and ecological niches of target fish communities in the lower reaches of the Kapuas River. Sampling was carried out using a purposive sampling method at 3 stations, namely the mouth of the Kapuas River in Jungkat and Sungai Raya, Kubu Raya Regency and the downstream part of the Kapuas River in Tayan Hilir, Sanggau Regency. Fish sampling was carried out using gill nets (5/9 inch mesh size) at each station with 3 repetitions set for 2 hours. At each station, samples were also taken of environmental factors consisting of substrate type, temperature, pH, DO and biological factors, namely plankton. The results of research on habitat preferences and ecological niches of fish communities in the lower Kapuas River show that there are 25 target fish species. The fish community in Terentang waters is different from the fish community in the Raya River and the Kapuas River mura in Jungkat. The main factor that influences community differences in the downstream Kapuas River is the amount of salinity. Ecological niche analysis shows that most of the target fish in the downstream Kapuas River are fish that are 55% carnivorous and the remaining 10% are carnivores, 20% are omnivores and 10% are herbivores. The types of fish food in the lower reaches of the Kapuas River mainly consist of phytoplankton, zooplankton, crustaceans, fish, molluscs and annelids.

Abstract

Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities. This study aims to assess the presence of plankton species, their abundance and diversity as aquatic ecological bio-indicators in Kakap River Estuary. Plankton and water samples were taken for three months, with a frequency of one sample per month, viz. in March, April and June 2020 from four sampling stations in Kakap River Estuary, West Kalimantan. A total of 34 species of plankton were observed from all sampling sites, and identified to belong to 18 classes. Chlorophyceae had the highest relative abundance among the phytoplanktons (40.10%), followed by Bacillariophyceae (21.86%) and Cyanophyceae (19.28%). Oscillatoria sp. and Hydrodictyon sp. were the most dominant phytoplankton species. There were 8 classes of zooplankton identified from all sampling stations throughout the research period. Hexanauplia had the highest relative abundance among the zooplanktons (36.56%) followed by Euglenophyceae (24.37%). The plankton diversity index (H ) values ranged between 2.33 -3.11. The plankton evenness index value ranged from 0.79 to 0.89 which indicates high plankton evenness at all samping stations, and this is supported by a low dominance index value at all stations ranging from 0.06-0.16. Station 1 had high Shannon-Wienner diversity index score, while for station 2, 3, 4, their scores were in the moderate level. Overall. the diversity index of the plankton from all sampling sites indicated that the quality of the water had no pollution to light pollution level.Keywords:PhytoplanktonZooplanktonWater quality
