Abstract

Osteochilus melanopleurus (Kelabau in Indonesia) is a freshwater fish found throughout Southeast Asia, including Malaysia, Burma, and Indochina. This fish has a relatively high economic value in some locations, thus it has compelling economic motives to be cultivated. One of the most important aspects in fish farming or aquaculture activities is feed availability. Feed ingredients should have adequate nutrient content, abundantly available and inexpensive. Palm kernel meal (PKM) is one of the by-products of palm oil iondustry. Palm kernel meal contains adequate nutrients to be utilized in fish feed, in addition to being abundantly available and affordable. The purpose of this experiment was to examine the growth response of Kelabau fed various quantities of palm kernel meal (5%, 10%, 15%, and 20%). The results showed that 10% palm kernel meal inclusion produced the highest growth, daily growth rate, specific growth rate, and feed conversion ratio. However, statistical analysis showed that the addition of palm kernel meal had no effect on growth or the feed conversion ratio.

Abstract

Identification of the quality of void water after coal mining needs to be carried out in order to utilize the void as a place for fish farming. Identification of water quality, in the form of physical and chemical water. Physical and chemical parameters can influence the survival of cultivated biota, so research needs to be carried out to identify both physical and chemical water parameters related to aquaculture. The research method involves taking and measuring water samples in both in situ and ex situ settings. Measurements were carried out at three (3) sampling points, sampling four times. The parameters under observation include temperature, TSS (Total Suspended Solids), pH, brightness, dissolved oxygen (O2), biological oxygen demand (BOD), chemical oxygen demand (COD), nitrate (NO3), nitrite (NO2), ammonia (NH3), and hydrogen sulfide (H2S). A descriptive analysis of water quality is conducted, and the results are compared against the quality standards outlined in the Provincial Regulations of East Kalimantan, specifically, Number 2 of 2011, which pertains to Water Quality Management and Water Pollution Control (APPENDIX V, Class III). The results of the water quality analysis physically show that the temperature is 29.5 –31oC brightness 135 – 285 Cm, TSS 13.75 – 27.5 mg/L, Chemical pH 7.42 – 7.68, O2 4.26 – 4.84 mg/L, BOD 0.64 – 1.84 mg/ L, COD 2.96 – 5.93 mg/L, NO3 0.026 – 0.049 mg/L, NO2 0.002 – 0.006 mg/L, NH3 0.01 – 0.13 mg/L and H2S 0 – 0.0087 mg/ L. Both the physical and chemical water quality parameters conform to the standards established in the East Kalimantan Province Regional Regulation Number 2 of 2011, which focuses on Water Quality Management and Water Pollution Control. As a result, the post-coal mining void water's condition, in both physical and chemical aspects, remains suitable for aquaculture.

Abstract

The potential of Selar Fish (Selaroides spp.) caught by fishermen in the waters of Donggala Regency requires in-depth study to support sustainable management and ensure its sustainability in the future. This research aims to analyze catch per unit effort (CPUE) as well as the maximum sustainable potential of trevally (Selaroides spp.) in the region. The research location covers three administrative areas, namely Labean Village (Balaesang District), Ogoamas Village (North Sojol District), and Labuan Bajo Village (Banawa District). The research results show that the average trevally production during the 2017-2023 period reached 5,019.06 tons per year, with an average fishing effort of 2,479.66 trips per year. The average catch per attempt (CPUE) was recorded at 2,394.92 tons/trip. Based on analysis using the Schaefer model, the maximum sustainable potential (hMSY) is obtained with a maximum biological production of 6,238 tons per year. Maximum economic profit is achieved at a hMEY production level of 6,152 tons per year, while the equilibrium condition for fisheries in open access (hOAY) occurs at a production level of 2,579 tons per year. In terms of fishing effort, the biologically optimum number of efforts (EMSY) is 3,175 trips per year, economically (EMEY) it is 2,803 trips per year, while in open access conditions (EOAY) it reaches 5,606 trips per year. This data indicates that MEY-based management is more advisable to maximize economic benefits while maintaining the sustainability of trevally resources. These findings can be a basis for policy makers in establishing sustainable fisheries management strategies in the waters of Donggala Regency
