Abstract

Climbing perch (Anabas testudineus) is one type of swamp fish that has the potential to be cultivated. The obstacle faced in the development of quail aquaculture is its slow growth because it takes 6-7 months to reach a length of 8-10 cm and a weight of 15-16 grams. The food for quail is usually eaten by aquatic plants such as water lettuce (Pistia stratiotes), weeds, other small animals, and insects. Feed is one of the main factors that can support fish breeding. As a place for fish to live, water quality is strongly influenced by physical and chemical factors of water such as temperature, dissolved oxygen, pH, ammonia, nitrite, and nitrate. Because the use of freshwater media added with salt has several advantages, it can inhibit the growth of fungi and increase antibodies against disease attacks. The objectives and plans of this research are. To determine the effect of different doses of maintenance media on the spawning of quail (A. testudieneus Bloch). Morever, to find out and provide the best optimal dose for rearing quail (A. testudieneus Bloch). It find out the best dose for spawning quail (A. testudieneus Bloch). It be used as a reference for further research ?. Hopefully, this study can provide benefits and insights for the cultivation technology of quail (A. testudieneus Bloch) either continuously or in a way that is good for its living media.

Abstract

This research is expected to be useful for fish farmers as additional information in catfish (Clarias gariepinus) aquaculture. The method used is an experimental method using a completely randomized design (CRD) with 5 treatments and 3 replications, namely:P1 = 1 minute immersed in Muntingia calabura leaf extract waste, P2 = 3 minutes immersed, P3 = 5 minutes immersed, P4 = 7 minutes immersed and P5 = 9 minutes immersed. 2.250 eggs of catfish (C. gariepinus) were obtained from artificial spawning of catfish broodstock at the Fish Seed Center, Faculty of Agriculture, Islamic University of Riau. The container used is a jar with a size of 10 liters. Based on the results of research on the effect of immersing waste extracts of M. calabura leaf extract with different immersing times on incubation time, hatchability and survival of catfish larvae, the best treatment was P5, which was 9 minutes of immersion. The parameter results obtained were 92% of egg adhesive, incubation time is 17:24 (17 hours 24 minutes), and hatchability rate is 87.78%. While the results of water quality measurements in this study were classified as optimal for catfish cultivation, with an ammonia range are 0.27-0.75 ppm, DO ranged from 3.14-4.95 mg/l, temperature are 28-31°C and the pH is 6.5.

Abstract

This research is expected to be useful especially for fish farmers as additional information in raising baung fish. The method used was an experimental method using a Completely Randomized Design (CRD) with 4 treatments and 3 replications namely: P1 = 5 ‰ per 3 days 7 ‰ per 3 days, 9 ‰ per 3 days, P2 = 5 ‰ per 5 days 7 ‰ per 5 days 9 ‰ per 5 days, P3 = 5 ‰ per 7 days 7 ‰ per 7 days 9 ‰ per 7 days, P4 = 5 ‰ per 9 days 7 ‰ per 9 days 9 ‰ per 9 days. The baung fish used for the study was obtained from spawning at the Fish Seed Center (BBI) of the Faculty of Agriculture, Riau Islamic University with a weight of 0.14 gr of baung fish/tail and 1.6 cm in length/tail. The container used is a jar a size of 10 liters. From the results of the study obtained the best absolute weight growth and absolute length of the treatment (P4) with a weight of 4.35 gr and a length of 1.84 cm, followed by treatment (P2) with a weight of 3.96 gr and P3 a length of 1.82 cm, (P3 ) weighing 3, 75 gr and P2, 1.73 cm long, and the lowest in treatment (P1) with a weight of 2.64 grams and a length of 1.28 cm. The daily weight growth rate in the treatment group (P2) was 17.31%, (P2) 15.17%, (P4) 13.18%, and the lowest (P3) was 12.60%. The best survival rate for treatment (P4) was 72.00%, followed by treatment (P3) at 54.67%, and the lowest for treatment (P1) was 6, 67%. The results of water quality measurements in this study were temperature 28-300C, pH 6-7, dissolved oxygen 0.4 ppm, ammonia 0.05 ppm. Based on the observations of water quality during the study was within the range of tolerance for the growth and life of baung fish.

Abstract

Liquid Organic Fertilizer (POC) has a high amount of nutrients that can be used as a nutrient source for the growth of Chlorella sp. This research aimed to determine the effect of Liquid Organic Fertilizer on the growth and abundance of Chlorella sp. cells and to obtain the optimal dosage of Liquid Organic Fertilizer for the growth of Chlorella sp. This research was conducted at the Laboratory of Microalgae and Fish Nutrition, Faculty of Agriculture, Islamic University of Riau. The research used a Completely Randomized Design (CRD) with four treatments, specifically giving POC doses of 2.5cc, 5cc, 7.5cc, and 10cc/l of water with three repetitions. The measured changer is growth and abundance, biomass, and parameters of the culture media such as temperature, pH, nitrate, and phosphate. The research results obtained the highest abundance of Chlorella sp. cells. amounted to 7,966,667 cells/ml at the POC dose of 5 cc/l of water, and the peak was on the 16th day, the lowest dose of 2.5 cc/l was 6,483,333 cells/ml, cell-specific growth rate Chlorella sp. during the study ranged from 0.074-0.087/hr. The highest amount of biomass was 0.3629 gr/l, parameters of the culture media such as temperature ranged from 26-30oC, pH of 6-8, nitrate 1.976-4.802 mg/l and phosphate 0.360-2.680 mg/l.
