Abstract

Viral inhibitor protein (VIP) contributes to shrimp resistance against virus infection. VIP can be used as a new strategy to control white spot syndrome virus (WSSV) infection in shrimp culture by inhibiting its action. This study aimed to evaluate the application of VIP on the whiteleg shrimp (Litopenaeus vannamei) to inhibit the WSSV infection. Shrimp at an average body weight of 6.66±0.08 g was injected by recombinant VIP with two different concentrations (1 μg/g and 10 μg/g) and challenged with WSSV. As a positive control was the shrimp not injected with recombinant VIP and challenged with WSSV, and as a negative control was the shrimp not injected with recombinant VIP and not challenged with WSSV. The results showed that the survival rate of shrimp that were injected with recombinant VIP was significantly increased after being challenged with WSSV (P<0.05). The survival and immune response of shrimp that were injected with recombinant VIP were higher than the positive controls (P<0.05). In this study, the application of recombinant VIP can significantly increase the shrimp resistance against WSSV up to 95.65% higher than the positive control.

Abstract

The adaptation of African (Clarias gariepinus) and striped catfish (Pangasianodon hypophthalmus) on peat water with low pH­ was successfully done. The treated fish were reared on a mixture gradient of peat water and borehole water in the fiber tanks as an adaptation process, with a control treatment of 100% borehole water. After adapting to 100% peat water, catfish were then transferred into the enclosure nets (hapa) and placed on a man-made peat water pond. The mortality, length, weight of catfish, and water quality parameters were recorded and measured. Results showed that subject catfish can be adapted and adapt with peat water of low pH from the fingerling size to adult with small mortality. Fish were acclimatized and gradually adapted after 58 days in the fiber tanks with nearly 100% peat water, and let for the next 38 days. The growth rate of both catfish between the treatment and control tank did not significantly differ. Fish was then moved to the enclosure nets on the ponds after 96 days. This indicates that by adaptation mechanism, catfish can survive and grow in peat water of low pH and possibly be reared in dynamic peat waters (rivers, lakes, and ponds).

Abstract

The Covid-19 pandemic that has occurred since 2020 is thought to have a different magnitude of impact on each type of catfish farming in Kampar Regency. This study aimed to analyze the structure of costs and revenues as well as differences in income from catfish farming based on the type of farming in Kampar Regency before and during the Covid-19 pandemic. This research was carried out in Koto Mesjid Village and Kuok Village from November 2021 to June 2022. The sample in this study was 60 farmers who farmed catfish for smoked fish raw materials were determined using a purposive sampling technique, and 60 farmers who farmed catfish for consumption were determined using a simple random sampling technique. The analytical method used is the structure of costs and revenues analysis, income analysis, and different tests. The results of the analysis show that there is a significant difference between income earned before and during the Covid-19 pandemic. However, there is no significant difference in income obtained between types of farming. Based on the R/C ratio of cash costs, catfish farming as raw material for smoked fish is financially feasible. However, based on the R/C ratio of total costs, no catfish farming is economically feasible to run during the Covid-19 pandemic.

Abstract

The increase in shrimp culture causes problems with the quality of seawater which is a source of water for whiteleg shrimp culture it self. The use of artificial brackish water as a culture medium is an effort to increase the availability of water sources for whiteleg shrimp culture. This study aims to (1) determine the optimum stocking density of whiteleg shrimp culture using artificial brackish water salinity based on carrying capacity, (2) determine mineral content (Mg, Ca, Na and K) in artificial brackish water, (3) study the effect of salinity on the growth and blood glucose concentration of whiteleg shrimp cultivated in artificial brackish water, (4) examine the effect of salinity on hemolymph osmolarity of whiteleg shrimp cultivated in artificial brackish water. This study used an experimental method consisting of two stages. Each stage was arranged using a completely randomized design (CRD). Obtained stocking densities of SD-50% (20 shrimps/50L), SD (40 shrimps/50L) and SD+50% (60 shrimps/50L). The best growth and performance were obtained in the treatment of 20 individuals, namely survival (SR) 87%, specific growth rate (SGR) 3.26%/day and hemolymph glucose concentration of 30.73 mg/dl. In the next stage of the research, the salinity treatments tested were seawater, 10 ppt, 15 ppt, 20 ppt and 25 ppt. The best shrimp performance was obtained in treatment 20 shrimps/50 L, namely survival rate 70.00%, specific growth rate (SGR) 1.55%/day, feed conversion ratio (FCR) 1.72, glucose haemolymp 73.44 mg/dl. The optimal osmotic work level (OWL) value is obtained at a salinity of 15-20 ppt.

Abstract

Fishing vessel is one of an important thing among a fishing unit. All fishing activities are carried out on fishing vessel. In Indonesia, the shape and size of fishing vessels are vary, depending on the habits of the fishers and the area where the fishing vessels are built and operated. In West Aceh Regency, there are fishing vessels with various sizes. This study aims to identify the shape of fishing vessels measuring less than 10 gross tonnages (GT) at the Fish Landing Base (PPI) Ujong Baroh, West Aceh Regency. This identification is intended as a basis for reference in formulating fishing vessel design that follows the local wisdom of fishers in West Aceh Regency. This reference fishing vessel design can help the government and other parties provide aid fishing vessel for fishers in West Aceh Regency. The direct observation and measurement of fishing vessels were used in this research. Descriptive and numerical method used in analysis data.  The number of sample was 27 fishing vessels consist of 10 sample with size of 1-5 GT and 17 with a size of 6-10 GT. The result show that fishing vessels in Aceh Barat District have a transom shape longitudinally and a round bottom or a round flat bottom shape transversely. All fishing vessels in West Aceh have a raked bow and a cruiser-shaped stern. The main dimensions ratio of group 6-10 GT is smaller than group 1-5 GT. The stability parameters of the two forms of fishing vessels follow the stability parameter values recommended by the International Maritime Organization (IMO). The static stability of fishing vessels with round flat bottom is better than round bottom.

Abstract

The carrageenan industry produces solid waste E. cottonii of 65% to 70%, so it had the potential to be used as a paper material. The aimed of this study was to analyze the effect of the concentration of E. cottonii waste which was added in the production of art paper from water hyacinth stems on the quality of the paper. The experimental design used was Complete Randomized Design with 1 factor, namely the difference of Eucheuma cottonii waste concentration (0%, 10%, 15%, and 20% (w/w)). The results showed that the addition of carrageenan processing from E. cottonii with difference concentration gave significantly different (p<0.05) on the value of grammage, tensile strength, tear resistance, density, and lightness of the paper. The best concentration of Eucheuma cottonii was 15% because it had the highest tear resistance value (p<0.05) and higher of lightness than the concentration of 0% and 10% (p<0.05). Paper with waste E. cottonii 15% had a grammage 148.93 g/m2; tensile resistance 1.28 kN/m; tear resistance 2497.37 mN; density 1.52 g/cm3; and lightness L* 80.19. The results of microstructure observations using Scanning Electron Microscopy (SEM) were the paper with E. cottonii waste 15% seen less free space (tighter) than other papers. Based on the grammage and tensile resistance value, paper with E. cottonii waste 10% according to Indonesian National Standard 8218:2015 regarding paper and cardboard for food packaging requirements.

Abstract

This study was prompted by an earlier study that revealed the absence of gonads in all fish species caught around the Itoku tributary of the Ogun River, an area known for active textile activities. Thus, this study investigated the effect of textile wastewater on reproduction biomarkers in African catfish broodstock. Male and female broodstock were exposed to varying pre-determined concentrations (0ppb-T0, 0.5ppb-T1, 0.35ppb-T2, 2ppb-T3) of the textile wastewater for a period of 96 hours. Water quality parameters, seminal/ovarian hormones, metabolites, ions, oxidative, enzymes, and sperm viability were assayed. The water quality parameters of the wastewater indicated varying degrees of physical and chemical pollution. The values of hormones were significantly different (p<0.05) although a trend was not observed. Prolactin, however, showed a marked difference statistically across the treatments in the male broodstock while a reverse trend was observed in the female broodstock. The values recorded for seminal metabolites increased significantly compared to the control except for T3 for cholesterol and T1 glucose which were significantly lower than the control. In the female broodstock, the values for glucose and creatinine significantly increased compared to the control. Seminal ions evaluated showed significant differences across treatments. Except for T1, there was a significant reduction observed in the values of sodium, chloride, and calcium compared to the control. For ovarian ions, a significant increase was recorded across the treatments compared to the control. However, sodium recorded a significant decrease compared to the control except for T3 where the value was higher than the control. In the male broodstock, aspartate aminotransferase and alanine aminotransferase values were significantly lower compared to control while an opposite trend was observed in the female broodstock. The concentration of sperm and life- to-death ratio significantly reduced across treatments compared to the control. These results indicate that the textile wastewater altered the reproduction biomarkers in the male and female broodstock. The implication of this is that reproduction in fish might become a challenge in textile wastewater polluted Itoku tributary of the Ogun River.

Abstract

This study investigated the performance of artificial feed in the Integrated Multi Trophic Aquaculture (IMTA) system through a combination of milkfish, tiger shrimp, and clam involving paddy in brackish water. The three combination groups (C) and triplicate including milkfish and paddy (C-2), milkfish, tiger shrimp, and paddy (K-3), and milkfish, tiger prawns, clams, and paddy (C-4) were examinated for 80 days on a model sheeting pond designed to have a volume of 280 L and a density of 30 individuals. Meanwhile, 30 clumps of paddy were maintained through the floating method which is constructed from bamboo with an area of 1 m2. Feeding 3 times a day with 5% of biomass resulted a mean Feed Conversion Ratio (FCR) and Index Profit (IP) of 2.1 and 2.0 for C-2, 2.0 and 2.9 for C-3, and 1.9 and 3.1 for C-4, respectively. The results showed that the best trend pattern were the combination of C-3 species which were statistically found to have a significant effect (P<0.05) on FCR and IP performances. The findings of current study have practical significance for the expansion of co-culture of paddy and aquatic animals in brackish water which important by ecologically, biologically, and economically.

Abstract

The environment is an important aspect and can be an indicator of the success of whiteleg shrimp culture. Stable water quality is a condition when water quality meets the requirements of growing whiteleg shrimp. This study aims to determine the aquatic environmental factors on the growth of whiteleg shrimp. There were 3 ponds observed in this research with an area of 2.000 m2, 2.500 m2, and 350 m2 respectively. The result of the research shows that the water quality of whiteleg shrimp culture is still in the feasible category. Several parameters show fluctuated results beyond optimal values such as dissolved oxygen, salinity, total ammonia nitrogen, and total organic matter. The results of the correlation test showed that all the quality parameters of whiteleg shrimp culture had varying degrees of relationship. The highest correlation level was obtained in salinity, nitrate, nitrite, ammonia, temperature, and dissolved oxygen. Water quality in each pond has a very strong relationship to the growth of mean body weight (10.31 g, 10.92 g, and 11.39 g), average daily growth (0.4142 g, 0.4971 g, and 0.3557 g), and survival rate (92.4%, 92.4%, and 92.3%).

Abstract

This study aimed to analyze Microplastics (MPs) contamination in brown algae and sediments, and their bioaccumulation factors, and estimate the risk to human health associated with exposure to ingested MPs collected from the water of the Sanur Beach, Bali Province. The samples were collected from three beaches which were determined using a purposive sampling method. The mean number of MPs found in P. australis was the same on all beaches, namely 17 items/seaweed, higher than S. aquifolium on all beaches. Line-shaped MPs were dominantly found in all algae (98.76%). A high percentage of line-shaped MPs was   found in sediments at Mertasari and Semawang Beaches, but not at Sindhu Beach. The highest mean size of MPs in algae was found in P. australis at Semawang Beach, and sediments at Mertasari beach. The highest concentrations of MPs were also found in P. australis on the three coasts. The BAF value showed that the absorption of MPs in the sediment to brown algae was still low (<1). Values related to intake of brown algae consumption ranged from 190.58-1429.41 MPs item/week adjusted for calculation recommendations.
