Abstract

Tinfoil barb (Barbonymus schwanenfeldii) is freshwater fish found in Borneo, Java, and Sumatera including in Aceh Province waters. It is known as a native species in Indonesia, locally known as Tengadak or Lampan and this species is popular for consumption due to its taste.  Tinfoil barb is targeted species of inland water for fisheries production. In recent years, the fish population has declined because of overexploitation and habitat degradation. Therefore, this study aimed to analyze the effects of temperature on Tinfoil barb (B. schwanenfeldii) eggs incubation using a funnel system. It was conducted at Balai Benih Ikan (BBI) Lukup Badak, Central Aceh Regency. The Completely Randomized Design was used as a statistical analysis method with four treatments and three replications at 22±1 oC, 25±1 oC, 28±1 oC, and 31±1 oC. Hatching was carried out using a funnel system with 100 grain/liter of eggs density for incubation. The parameters measured were hatching time and rate, egg yolk absorption time, the survival rate of the embryo, larvae abnormality, and water quality. The ANOVA test results showed that temperature significantly affected hatching time and rate, egg yolk absorption time, and larvae abnormality (P0.05). In contrast, the effect was insignificant on the survival rate of an embryo, with P0.05. It is concluded that the optimum temperatures for Tinfoil barb eggs incubation were about 25±1 oC–31±1 oC. A funnel system was more effective for incubation than the conventional system.Keywords:Tinfoil barbFishIncubationTemperatureFunnel System

Abstract

Post-larval snakehead (Channa striata) can be fed on live silkworms (Tubifex sp.), artificial feed and a combination of both as a source of nutrients. The availability of live silkworms depends on the yield in nature. Meanwhile, dried silkworms are available in the market. Therefore, the study to evaluate feeding combinations of dried silkworms and artificial feed for the rearing of post-larvae snakehead was conducted from October to December 2020 in Serang District, Indonesia. The treatments were combinations of dried silkworm and artificial feed at a ratio of 100:0%, 75:25%, 50:50%, 25:75%, and 0:100%, respectively. After being adapted to experimental conditions, post-larvae of snakehead (0.40±0.02 g) were randomly stocked in 15 happas of 50x70x75 cm in dimension size each at a rate of 25 post-larvae and fed on tested diet according to the treatments at 5% of biomass a day, divided into three times for 40 days of experimental periods. The post-larvae of snakehead performed the best growth at the contribution of dried silkworm at 100 – 25%, the best feed conversion and protein efficiency ratio at 100 – 50% and 50%, respectively and the best survival at 50 – 0%. It could be suggested that feeding dried silkworm and artificial feed at a 50:50 ratio, respectively, during post-larvae snakehead rearing.Keywords:Channa striata Feeding combination Nutrient sourcesPost-larvae rearing

Abstract

The Atomic Absorption Spectrophotometer method (AAS) and UV-Vis Spectrophotometer method are often used in analyzing elements and compounds in water and sediment. The comparative method of AAS and UV-Vis analysis in sediments in this article is studied to see the accuracy of the equipment used and the efficiency of the resulting analysis. Analysis of the comparative method of phosphate analysis in coastal sediments shows differences and similarities in the use of the two instruments used even though the methods used based on the results of the review do not show significant differences. Methodologically, various types of methods can be carried out to analyze coastal sediment phosphates. The UV-Vis spectrophotometric method is generally more widely used than the AAS method. For a small number of sediment samples, the ASS method is more efficient than the UV-Vis method; however, UV-Vis is more accurate for dissolved samples because less phosphate is released when identified than the AAS method. Based on this, the AAS method is more effective in analyzing phosphate sediments in coastal areas than the UV-Vis method, but the UV-Vis method for wet samples is more accurate.Keywords:Coastal SedimentPhosphateSpectrophotometerUV-VisAAS

Abstract

This study aims to evaluate the culture performance of tilapia (Oreochromis niloticus) that have been treated with 17α-methyltestosterone (MT) and without MT (w-MT), feed with different protein levels (20, 24, and 28%) and recombinant Epinephelus lanceolatus growth hormone (rElGH)-diet. The research was conducted in 9 treatments and triplicate. Tilapia larvae were soaked twice, totaling 500 larvae, at the age of 10 days after hatching (DAH) and the age of 14 DAH was soaked for 4 hours using 1/l MT 2 mg/l solution. Fish maintenance was conducted in an aquarium of 1.0x0.5x0.5 m3 in the first month, and three months later in net cages (2.0x2.0x1.5 m3). Daily growth rate (DGR) and biomass gain (BG) were increased in line with increasing feed protein content and rElGH supplementation. The highest DGR and BG values were MT+28+rElGH (P 0.05) treatment. The highest feed consumption and the lowest feed conversion ratio were also obtained in the MT+28+rElGH treatment (P 0.05). Fish survival was ranged from 79.89 to 90.28% (P 0.05). The highest profit potential was found in the MT+28+rElGH treatment. The efficient aquaculture can be obtained by feeding sex-reversed tilapia at a protein level of 28% and a diet supplemented with rElGH.Keywords:Feed conversion ratioGrowth hormoneProtein retention17α-methyltestosterone

Abstract

The scad (Decapterus sp.) is one species commonly caught using purse seine and landed at the Pusong Fish Landing Base, Lhokseumawe, Aceh. The fishermen at this site do not have accurate knowledge about the fishing season of the scad, which leads them to miss out on peak fish catching season and increases the ambiguity about the fish landing data. The goal of this research is to compute the trend of Catch Per Unit Effort (CPUE) for scad fisheries over the last five years (2013-2017) and to examine the fishing season trends of scad landed at Pusong fish landing base. This study took place at the Pusong Fish Landing Base in August 2020. The moving average approach was used to process catch data from 2013 to 2017. Primary and secondary data about scad production and number of fishing trips were used to compile the research findings. The results showed that the CPUE for purse seine catch landed at Pusong Fish Landing Base varies from year to year. The highest CPUE value was recorded in 2015 with 442,534 kg/trip, and the lowest was in 2013 with a value of 27,674 kg/trip. The fishing season index for Scad (Decapterus sp.) has a high rating, indicating that this fish species can be caught all year. Based on the fishing season identification criteria, the fishing season index value greater than 100% indicates the peak season. Results from this research indicate that the peak season for scad landed at Pusong Fish Landing Base occurs in July, August, September, October, and November, with their index values of 151%, 146%, 119%, 122%, and 126% respectively. A fishing season index score of less than 100% indicates low season, this was recorded for January, February, March, April, May, June, and December (48%, 97%, 57%, 90%, 62%, 86% and 97%).Keywords:ScadFishing Season IndexCPUE

Abstract

This study aims to determine the effectiveness of Oodev and Turmeric flour on feed to accelerate the rematuration of female broodstock catfish for increasing seed production. Oodev hormone is believed to accelerate the maturation process of broodstock, while turmeric flour with its active ingredients can improve liver performance in the vitellogenesis process. The method was a non-factorial completely randomized design with 4 treatments and 3 replications. The treatments are Control, (A) Oodev 0.3 ml/kg of feed, (B) Turmeric flour 5 gr/kg of feed, and (C) Combination of Oodev + Turmeric flour. The results showed that C treatment was the best treatment which produced a GSI value of 14.57 ±2.53%, period of rematuration was 32.33 ±4.16 days, egg diameter was 1.27 ±0.12 mm, fecundity was 22,939.97 ±880.38 eggs/kg of broodstock weight, fertilization rate was 80.18 ±9.75%, hatching rate was 79.80 ±2.88%, and larval survival reached 83.17 ±9.69%. Meanwhile, the specific growth of seed length in all treatments had no significant effect between treatments. The results of this study will certainly provide useful information for increasing catfish seed production both in Aceh and on a Nationally. This acceleration of maturation also has a positive impact in maximizing the available broodstock without having to increase the number of catfish broodstock to produce seeds of superior quality and benefit the cultivators.Keywords:EnrichmentFemale BroodstockPerformanceRematurationReproduction

Abstract

Coastal areas have an important role and have high natural resources that can be utilized for human life. Over time, the increase in population is directly proportional to the activities and utilization of coastal areas, which puts great pressure on coastal areas. One of the pressures that occur in coastal areas is heavy pollution. This research aims to see the distribution of heavy metals especially Cd, Cu and Pb in the coastal areas of Jakarta Bay and Semarang Bay and to see the differences in heavy metal content from the two gulfs. The data used in this study is secondary data, which consists of data on heavy metals, current velocity, pH and water temperature. The period of data used in this research are from 2016 to 2019, The method used in this study is the GIS method with descriptive analysis. The comparison of concentrations from two bays shows a higher mean of concentration value of heavy metals cadmium (Cd) in Semarang Bay (2016, 2017, 2019) and heavy metals of copper (Cu) in Jakarta Bay (2016 and 2018). Meanwhile, the concentration value of heavy metal lead (Pb) was higher in Jakarta Bay (2016, 2017, 2018), yet in 2019, the two locations have the same concentration value of heavy metal lead (Pb). Keywords:Coastal areaDistributionHeavy metalsJakarta BaySemarang Bay

Abstract

 Singkil Swamp Wildlife Reserve is a peat swamp ecosystem located in Aceh Singkil Regency, Aceh Province. Peat swamp ecosystem has an important function in protecting and balancing water systems, carbon stocks and biodiversity conservation. However, information on the characteristics of the waters of this ecosystem is still not widely known, especially in the area of utilization that is influenced by community activities. This study aims to determine the aquatic environmental characteristics of the Singkil Swamp Wildlife Reserve utilization area covering the physical and chemical parameters of the water and the relationship among those parameters. Sampling was carried out through field observations both in-situ and ex-situ at 5 stations for 3 months (April-June 2021). Observations were made on water quality parameters namely temperature, transparency, depth, current, colour, salinity, water smell, pH, DO, TDS, TSS, conductivity, phosphate and nitrate. Analysis of the data was conducted, namely correlation analysis, PCA (Principal Component Analysis) and CA (Cluster Analysis). The water color was black and the pH was acidic, that is a characteristic of the swamp waters. The results of the measurement of water quality parameters indicate that TDS (13-44 mg/l), TSS (9-236 mg/l), total phosphate (0.01-2.14 mg/l), and nitrate (0.5-25.7 mg/l) were suitable for freshwater aquaculture to support fishery reserve. Based on the clustering of those stations, 5 observation stations were grouped into two different groups, namely cluster 1 with the number of observation stations of 2 stations (Stations 1 and 2) and cluster 2 with the number of observation stations of 3 stations (3, 4 and 5). The parameter values of total phosphate, pH, DO, and nitrate in cluster 1 tend were higher than in cluster 2.Keywords:Peat swampFreshwaterWater quality
