Abstract

Situ Gede is one of the artificial lakes/reservoirs in Tasikmalaya, West Java. The lake has functioned as a source of household water needs, fisheries, and tourism. According to determine the development of water management requires information on the trophic status and water quality. This study aimed to obtain information on the trophic status and water quality of Situ Gede. The research was conducted in Situ Gede, Tasikmalaya, West Java, in 2018. Measurement and analysis of water quality parameters used the SNI and APHA methods, while the measurement of trophic status used the Carlson Trophic State Index (TSI). The relationship between water quality parameters and TSI scores was analyzed using Statistica version 8. Based on the analysis, the trophic status of Situ Gede ranged from 69.06-79.04, with an average of 74.61. This value indicated that Situ Gede's trophic status was on a eutrophic level. The physical and chemical parameters that affect the trophic status of Situ Gede are TP, pH, conductivity, TDS, and temperature. The TP values, conductivity, pH, and temperature at Situ Gede were still categorized as normal. The trophic of Situ Gede can be a source of fish growth. Moreover, in general, Situ Gede waters still have sufficient water quality for fish life. Therefore, Situ Gede has the potential to capture fisheries, recreational fisheries, and aquaculture.Keywords:Trophic statusSitu GedeFisheryChlorophyll-aFish Reserve

Abstract

Large pelagic fish live on the water surface in groups. Skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), mackerel tuna (Euthynnus affinis), mackerel (Scomberomous guttatus) are species of fishes that mainly catches by fishermen using purse seines. This study aims to determine the length and weight of large pelagic fish in the water of Idi Rayeuk and best the fishing season. This research was conducted in one month. Fish samples were collected from fishermen that used purse seine and landed their catches at the Idi Rayeuk Fishing Port, East Aceh. Additionally, the data was derived from the fishing port time-series during 2015 to 2019. The result showed that the yellowfin tuna (Thunnus albacares) has a length between 37 - 58 cm with a weight of 1.0 - 3.2 kg, skipjack tuna (Katsuwonus pelamis) 32 - 58 cm in length and weight 0.5 - 3.0 kg, mackerel tuna has 33 - 54 cm of length with a weight of 0.6 - 2.5 kg, and mackerel has 44 - 66 cm of length and weighing 0.7 - 1.7 kg. Its also found that the peak season for catching yellowfin tuna (Thunnus albacares) and mackerel tuna is May and June, and the lowest season in December for the yellowfin tuna, and December and January for the mackerel tuna. The peak season for skipjack fishing occurs in May, August, and October, and the low season occurs in November and December. Meanwhile, the peak season for fishing mackerel occurs in May, September, and October, while the low season occurs in January, February, and March.Keywords:Fishing seasonLarge pelagicPurse seineIdi RayeukAceh

Abstract

The practical application of waste recycling as feed supplement is potentially required by small-scale aquaculturist. Furthermore, some of the flour derived from waste sea urchin shells and in adopted in feed, including Deadema setosum were evaluated to estimate the effect on white shrimp Litopenaeus vannamei moulting. This research required the experimentation of four doses with triplicate supplementation (0, 2, 4, and 6 g 100 g-1 of feed) on shrimps four times daily (12% of body weight) for 35 days test period. The juvenile specimens, characterized by an initial weight of 1.61±0.11 g, were stocked at a density of 12 individuals in a 12 L aquarium. In addition, four compartments were created in each aquarium to facilitate progress observations. The proximate analysis results showed a 53.76±0.27% calcium content in the shell flour, which significantly increased (P0.05) after higher dose supplementation, in the sequential order 18.65±0.13%, 20.04±0.08%, 23.18±0.10%, and 25.04±0.11%. Moreover, the frequency and moulting interval with 4 g doses (16.59%±0.36% day-1 and 5.91±0.18 days-1) were significant (P0.05) and considered the best, compared to 0 g (10.48% ± 0.24% day-1 and 9.97±0.37 days-1), 2 g (13.49%±0.96% day-1 and 8.10±0.29 days-1), and 6 g (13.81%±0.24% day-1 and 7.90±0.06 days-1). In addition, the respective trend pattern for both parameters increased and decreased at 4 g and 6 g, correspondingly. The highest moulting intensity was also obtained with the 4 g doses, at a range of 4 to 6 times, while the lowest (0 g) varied from 3 to 4 times. These sea urchin shell flour was determined to have numerous practical applications as a feed supplement with proven ability to stimulate moulting in vannamei shrimp.Keywords:MoultingCalciumShellSea urchinFeed supplementationVannamei shrimp

Abstract

Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities. This study aims to assess the presence of plankton species, their abundance and diversity as aquatic ecological bio-indicators in Kakap River Estuary. Plankton and water samples were taken for three months, with a frequency of one sample per month, viz. in March, April and June 2020 from four sampling stations in Kakap River Estuary, West Kalimantan. A total of 34 species of plankton were observed from all sampling sites, and identified to belong to 18 classes. Chlorophyceae had the highest relative abundance among the phytoplanktons (40.10%), followed by Bacillariophyceae (21.86%) and Cyanophyceae (19.28%). Oscillatoria sp. and Hydrodictyon sp. were the most dominant phytoplankton species. There were 8 classes of zooplankton identified from all sampling stations throughout the research period. Hexanauplia had the highest relative abundance among the zooplanktons (36.56%) followed by Euglenophyceae (24.37%). The plankton diversity index (H ′) values ranged between 2.33 -3.11. The plankton evenness index value ranged from 0.79 to 0.89 which indicates high plankton evenness at all samping stations, and this is supported by a low dominance index value at all stations ranging from 0.06-0.16. Station 1 had high Shannon-Wienner diversity index score, while for station 2, 3, 4, their scores were in the moderate level. Overall. the diversity index of the plankton from all sampling sites indicated that the quality of the water had no pollution to light pollution level.Keywords:PhytoplanktonZooplanktonWater quality

Abstract

Nile tilapia is a freshwater fish that is widely cultivated in Indonesia. During its development, tilapia aquaculture has constraints such as low growth rates. Therefore, it is necessary to add a feed additive to the feed in the form of charcoal. Charcoal is an adsorbent that has high absorption so that the addition of charcoal in the feed can increase the absorption of nutrients of tilapia. A 45-days trial was conducted to determine the percentage of addition of triggerfish bone charcoal (Abalistes stellaris) as a feed supplement that affect the growth performance and intestines of tilapia. The research design was a non-factorial Completely Randomized Design (CRD) with 4 treatments and 2 replications as treatments including: treatment A (control), B (addition of 1%charcoal), C (addition of 2% charcoal) and D (addition of 3% charcoal). A total of 240 tilapia fingerlings (5-7 cm) were used and placed in 8 aquariums then filled with 72 liters of water. Providing adlibitum (unlimited) feed with a frequency of 2 times a day. The ANOVA test showed that the addition of triggerfish bone charcoal (A. stellaris) in the feed was not significantly different (P 0.05) in weight growth, absolute length and daily length growth but it was significantly different (P 0.05) in feed conversion ratio and the efficiency of feed utilization. Based on result, it was concluded that the addition of 3% charcoal was the best treatment which gave the lengthiest of villi which was increasing the length of the intestinal villi to 71.11 µm from the initial length of 162.22 µm. easel at 233.33 μm, showed the highest feed conversion ratio value and feed efficiency (1.12 %, 89.6%).Keywords:CharcoalFish boneIntestinal histologyStarry triggerfish
