Abstract

Water flea or Latin (Daphnia sp) is one type of natural food that is very important for natural fish feed. But these water fleas are very rare to find if not cultivated, especially in fresh water. This condition causes water fleas to be limited and need to be cultivated. This study aims to determine the effect of apu-apu (Pistia stratiotes l) as an organic fertilizer with different doses of water flea population (Daphnia sp). Usefulness of the research to provide information on the effects of apu-apu (Pistia stratiotes l) as organic fertilizer with different doses of the water flea population (daphnia sp). This research was conducted for two weeks starting from 02 - 17 May 2017. The research was conducted in the Laboratory of the Faculty of Fisheries of Palangka Raya Christian University. With the implementation method are: preparation of 9 (nine) aquarium for cultivation media of Daphnia sp, making of organic fertilizer, giving different dose respectively: treatment A: 0,25 gr / ltr water, treatment B: 0,50 gr / ltr water, C: 0.75 gr / ltr water treatment, and water quality observation. The results showed that the dosage of apu-apu (0,25) gr / ltr water, (0,50) gr / ltr water and (0,75) gr / ltr of water had a significant effect on the water flea population. Based on further experimental test of significant difference (BNT) with 99% confidence level, showed treatment A dose 0,25 gr / ltr water better than treatment B dose 0,50 gr / ltr water and treatment C 0,75 gr / ltr water and 0.5 gr / ltr water treatment is better than 0.75 g / ltr water. The average of water quality conditions in the maintenance of water fleas in Aquarium are DO = 5,23-5,29 ml / l, pH = 6,43-7,55, Temperature = 26,34- 26,56 C, TDS = 52,33-60.99 ml / l. Water quality parameters strongly support the presence of water flea population.

Abstract

This study aims to determine the adaptation of Seluang fish (Rasbora agryotaenia) based on the domestication stage of Sebangau waters. This research started in January until February 2018. The research method used is a survey and experimental observation. The size of the tarpaulin pond used for domestication is 2 x 3 m, with a water height of 30 cm. The number of fish sampled is 200 heads. Feed is given as much as 5% of the total weight of the fish kept, feeding done twice a day (morning and afternoon). This domestication activity is still not perfect, because only part of the life cycle of fish (Rasbora agryotaenia) can be done in the cultivation system (survival and eating commercial feed). During maintenance activities, the amount of feed used was 63.840 g with the final weight of the fish was 16.905 g. Survival rate (SR) of fish (Rasbora agryotaenia) during maintenance was 73.5% and deaths 26.5%. From the calculation is known that the Feed Conversion Ratio (FCR) for fish (Rasbora agryotaenia) 2.8. This domestication stage starts with the preparation of maintenance pools, fishing in nature, sorting, distribution, and maintenance. During maintenance, five samples of sample fish were taken and five times the pool water quality measurement. From the five weights of the sample fish, it is known that the average weight of the fish is kept, I = 0.003 g, II = 0.042 g, III = 0.051 g, IV = 0.082 g, V = 0.115 g. From the measurement of water quality of tarpaulin ponds, it is known that the mean value of water quality parameters, for DO ranges from 1.5 to 8.8 mg / L, the pH ranges from 5.5 to 7.2 and temperatures range from 27.4 to 27.7 0C.
