Abstract

This study aims to determine the growth and survival of kissing gourami (Helostoma temminckii) on a rearing medium given liquid biological fertilizer. This research was conducted from 01 April to 21 May 2022 at the Hatchery, Faculty of Fisheries and Marine, Universitas Riau. The container used was a bucket with a volume of 100 L. This study used a one-factor, Completely Randomized Design (CRD) method with five treatments and three replications. The level of treatment applied in this study was P0 = No treatment, P1 = treatment of 0.01 mL/L water, P2 = treatment of 0.03 mL/L water, P3 = treatment of 0.05 mL/L water and P4 = treatment of 0.07 mL/L. The results showed that applying liquid biological fertilizer with different doses significantly affected fish growth performance (P<0.05). The best treatment was found at a dose of 0.03 mL/L, which produced a range of ammonia (0.0043-0.0163 mg/L), nitrate (0.049-0.189 mg/L) phosphate (0.036-0.072 mg/L), absolute weight growth (10.07 g), absolute length growth (11.31 cm), specific growth rate (1.94%), feed conversion (1.08%) and survival (85, 00%).

Abstract

This research was conducted in Bagan Hulu Village, Bangko District, Rokan Hilir Regency, Riau Province on November 21 - December 09, 2022, to analyze the profit-sharing system for drift gill net fishermen and compare the profit-sharing system that applies in Bagan Hulu Village with the Law No.16 of 1964 concerning profit sharing. The method used was a survey with a total sample of 32 fisherman owners; the sampling technique was simple random sampling. The results showed that the profit-sharing system for drift gill net fishermen in Bagan Hulu Village, Bangko District, Rokan Hilir Regency, Riau Province, uses a local profit-sharing system by sharing profits after deducting production costs with a percentage of 60% for fisherman owners and 40% for labor fishermen provided that all operational costs are shared. From a comparison of the profit-sharing system according to UUBHP, the share of income for fishermen who own drift gill nets in Bagan Hulu Village is greater than that according to UUBHP. The difference can be seen from the joint costs incurred. In the law, the shared costs incurred are consumption, while in the Bagan Hulu Village, the shared costs incurred are all operational costs

Abstract

This research was conducted from February to March 2023 in Setan island, West Sumatra. This study aimed to determine the sediment accumulation rate and coral cover, as well as the correlation between sediment accumulation rate and coral cover. The survey method was used in this research. The sediment accumulation rate was measured using a sediment trap. At the same time, the coral cover was observed using the underwater photo transect (UPT) method with a transect length of 50 m. The total suspended solid was analyzed using the Gravimetric method. Observations were made at four sampling points at depths of 3 and 6 m. The sediment accumulation rate at a depth of 3 m ranged from 0.946315 to 1.534992 mg/cm²/day, while at a depth of 6 meters, it ranged from 1.357756 to 1.607786 mg/cm²/day. The percentage of live coral cover at a depth of 3 meters ranged from 3.40% to 31.36%, and at a depth of 6 m, it ranged from 0.33% to 30.50%. The total suspended solids values ranged from 23 to 96 mg/L. Regression analysis showed that the sediment accumulation rate negatively influenced the percentage of live coral cover

Abstract

Commercial feed contributes to the operational costs of aquaculture production activities. On the other hand, making your feed requires formulation and availability of raw materials in maintained quantity and quality. Local feed raw materials can be used as alternative ingredients. Still, one of the obstacles is several limiting factors, such as crude fiber and the binding of some essential nutrients, such as protein and minerals. Hence, nutrient utilization is low and has a direct impact on growth. Adding feed additives as sources of enzymes is considered to help speed up the digestive process so sufficient nutrients are available for growth and survival. Enzymes break down large molecules such as crude fiber starch, increasing protein and fat into forms easily digested and absorbed by fish. This paper aims to review the use of enzymes to improve the quality of fish feed ingredients. The method used is Literature Review. Improving the quality of feed raw materials with the help of enzymes can increase the quality of fish feed ingredients. Application of enzymes in fish feed as additional feed ingredients (feed additives) through the addition of commercial enzymes, enzymes from plant or animal extracts, and microbial enzymes

Abstract

Chlorella sp is a kind of phytoplankton used as a natural food source for zooplankton, such as fish larvae and shrimp. Chlorella sp contains various nutrients that are good for the growth of fish larvae and shrimp. The success in cultivating Chlorella sp is closely related to the nutrient content at the time of cultivation. One alternative cultivation of Chlorella sp is using bean sprout extract and coconut water as the medium. Bean sprouts and coconut water extract can be used as a substitute for inorganic fertilizers. This research aims to determine the effect of bean sprout extract and coconut water on the growth of the density of Chlorella sp, as well as grasping the best dose that can be used to cultivate Chlorella sp. This research was conducted in July 2022 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine, Universitas Riau. This research used a one-factor, Completely Randomized Design (CRD) with four treatments and three replications. The treatments as defined in this research were P0 (Walne fertilizer 1 mL/L as control), P1 (8% bean sprout extract + 10% coconut water), P2 (10% bean sprout extract + 12.5% coconut water) and P3 (bean sprout extract 12% + coconut water 15%). These results indicate that P3 (12% bean sprout extract + 15% coconut water) is the best treatment for the growth of Chlorella sp with a density of 1091.00 x104 cells/mL and a specific growth rate of 0.9607 sel/mL, which occurred on the sixth day.

Abstract

This research was conducted in January-July 2021 at the Marine Science Technology Biology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The purpose of the study was to see the effect of a combination dose of vitamin C and thyroxine hormone (T4) on the growth rate and survival of bream reared in a recirculation system. The method used was an experimental method using a factorial complete randomized design (CRD) with 2 factors and 3 replicates. The first factor is vitamin C, while the second factor is the dose of tyrrhosine hormone (T4) given during maintenance. The doses of vitamin C used in this study were; 0 mg/kg (V0), 500 mg/kg (V1), 1000 mg/kg (V2). Doses of thyroxine hormone (T4) used were doses; 0 mg/kg (H0), 4 mg/kg (H1), 6 mg/kg (H2), 8 mg/kg (H3).  The Asian redtail catfish used were 8-10 cm in size and reared in a round container made of PE plastic with a diameter of 56 cm and a height of 48 cm, totaling 36 units. The pellets used were Hi-Provite 781-2 with 31% protein, with feeding done 3 times a day ad satation. The results showed that the addition of vitamin C and thyroxine hormone influenced the growth of Asian redtail catfish reared in the recirculation system. The combination of vitamin C 1000 mg/kg and thyroxine hormone 8 mg/kg feed gives the highest growth and survival, seen from the absolute weight growth rate of 12.97 g, specific growth rate of 1.93 g/day, and 95% survival. Water quality during rearing was favorable for the growth of Asian redtail catfish, with temperature ranging from 28-30oC, pH 6.5-7.0, and DO 4.2-5.95 ppm.

Abstract

This study aims to determine the effect of feeding containing fermented chicken feather flour on feed efficiency and growth of striped catfish fry. The test fish used weighted 2.85 ± 0.33 g. The containers used for observing fish growth were 15 units of floating net cages made of gauze measuring 1x1x1 m with a stocking density of 25 ind/m, 3 and 5 units of aquariums measuring 60x35x40 cm as containers for observing the digestibility of feed with a stocking density of 25 ind/m3. This research method used a one-factor Completely Randomized Design (CRD) with five treatment levels and three replications. The treatments in this study were P0 (feed without fermented feather meal), P1 (feed containing 7.5% fermented feather meal), P2 (feed containing 15% fermented feather meal), P3 (feed containing 22.5% flour fermented chicken feathers), and P4 (feed containing 30% fermented chicken feather flour). The test feed protein was about 40%. The amount of feed given is 5% of the body weight of the fish with a frequency of 3 times a day, namely morning, afternoon, and evening. Fish rearing was carried out for 56 days. Measure the digestibility of feed by giving feed containing an indicator of 0.5% chromium oxide (Cr2O3). Feed is offered three times a day, namely morning, afternoon, and evening, as much as 5% of the body weight of the fish. The feces excreted by the fish are then collected and dried. The collected feces were analyzed for protein content and Cr2O3 to obtain feed and protein digestibility data. The results of this study indicated that the best treatment was P3 (feed containing 22.5% fermented chicken feather meal), resulting in feed digestibility of 55.36%, protein digestibility of 85.39%, feed efficiency of 83.59%, protein retention of 36.33%, specific growth rate of 3.38%, and survival of 92.00%
