More Information
Summary:According to the analysis results, the length and weight of fish living in the Buaya Lake and outlet river are smaller than those living in the Indragiri River. [...]valid data on fish stocks is necessary for evaluating over-exploitation of fishery resources, in areas where the fish management on peatlands has not been optimally implemented, including the Buaya Lake ecosystem. [...]rapid action to collect data on fish stocks and the breeding season is needed. Temperature affects swimming activity, speed, and endurance (Nofrizal et al 2019; Nofrizal & Arimoto 2011; Nofrizal et al 2020), and pH affects physiology, stress status, and growth performance (Mota et al 2018). [...]temperature data is required as an indicator of fish habitats in the waters of the study location. Biologically, the relationship between the length-weight of the individual is not similar in each species, due to physiological factors. [...]the measurement of length or weight can be used to predict the length-weight relationships (LWRs) by utilizing the best formulation.
