Abstract

                                                  Abtract This research was conducted in December until January 2018 in the  Fish Breeding and hatcheryDepartment of Aquaculture, Marine Fisheries Faculty University of Riau, Pekanbaru. The purpose of this research is to know how the replacement of Artemia nauplii with worm Tubifex sp. on the rearing of fish larvae (Anabas testudineus). The treatments  applied in this study were the P1: feeding Artemia nauplii(40 days) P2: feeding Artemia nauplii (10 days) and feeding Tubifex sp. (30 days) P3: feeding Artemia nauplii after (20 days) and feeding Tubifex sp. (20 days) P4: feeding Artemia nauplii (30 days) and feeding Tubifex sp. (10 days), P5: feeding Tubifex sp. (40 days). The results showed that the worm Tubifex sp. Artemia nauplii can be replaced as feed early or up to 20 days. Maintenance on the larvae of fishes anabas were 1.17 grams of absolute weight growth, 5.81 cm of absolute length growth, specific growth rate was 11.92% and Survival Rate was 83.33%. Water quality during the study i.e. the temperature range was 26-290C, pH range was between 6-7 and DO was 4.2-5.2. Keywords : Replacement, Artemia nauplii, Tubifex sp. Walking Fish Larvae (Anabas testudineus)

Abstract

PLTU Teluk Sepang Bengkulu City produces heat waste dumped back into the sea which affects the quality of the water so that it has a negative impact on marine life. This study aimed to identify the quality of the water around PLTU Teluk Sepang Bengkulu City based on the physical and chemical parameters. The method used was direct measurement at the research location which is carried out at 12 measurement points,i.e 4 points around the outlet area, and 8 points in the off-shore area. The measurement result was compared with seawater quality standard for marine biota based on the Minister of Environment Decree No. 51 of 2004 and was validated by analysis of sea water quality before the PLTU had operated. The result showed that the some parameters met the quality standards for marine biota included DO of 5.62-7.82, pH and turbidity in the offshore area with each value of 7.24-7.86 and 1.68-4.846 NTU. Meanwhile, the parameters which did not meet quality standards include a temperature of 30.62-36 ºC, a salinity of 26.6-30 ‰,  pH and turbidity around the outlet area with each value of  6.7-6.88 and 23.25-146.8 NTU. Based on the validation result, it showed that heat waste had a very significant effect on the physical and chemical parameters of the waters, especially on temperature, pH, and turbidity.
