Abstract

Highlight ResearchThe reproductive characteristics of L. hoevenii were examinedThe potentially smallest maturity sizes of female and male L. hoevenii were 350 g and 180 g, respectivelyThe fecundity of a 1,000 g L. hoevenii can be more than 100,000 eggsL. hoevenii was determined as a multiple spawnerAbstractSultan fish (Leptobarbus hoevenii) is a high value freshwater fish, cultured in some Southeast Asian countries, including Malaysia and Thailand. However, information on its reproductive characteristics is very scarce. This study examined the gonadosomatic index (GSI), fecundity, egg diameter, and determined whether L. hoevenii is a single- or multiple-spawner. Twenty male and female pond-farmed L. hoevenii broodstock were obtained to measure their total length (TL), body weight (BW) and gonad weight to calculate the GSI. Ten females were randomly sampled from the 20 to determine their fecundity. A total of 1,500 eggs were sampled from each female. The egg diameter was measured then its frequency distribution was analyzed to detect the number of egg class group, and to determine whether L. hoevenii is a single- or multiple spawner. The female L. hoevenii examined were 32.2-47.1 cm and 350-1,200 g, while the males were 30.7-45.8 cm and 180-970 g in TL and BW, respectively. All female specimens contained gonads. The potentially smallest mature samples were recorded at 350 g (female) and 180 g (male). GSI for the female and male L. hoevenii were 1.81-12.28 % and 1.03-5.09 %, respectively. The fecundity was 35,467 -128,067 eggs, while the highest fecundity was observed in a 1,000 g fish. The observed egg diameter ranged from 500 to 1,855 μm. Two to five groups of egg class were detected, indicating that L. hoevenii is a multiple spawner.

Abstract

Highlight ResearchThe fishing area of S. leptolepis in this study was confirmed to be located in Tomini BayThe fish samples were gathered randomly from fishers' catch using purse seinesThe growth curve for the male and female fish data were both plotted following the trend of the Von Bertalanffy equationThis study estimates the growth parameters, mortality, and exploitation rates of the male and female fish separately.AbstractComprehensive data is required for implementing sustainable fisheries management. Population dynamic and stock assessment aspects of Selaroides leptolepis species in Tomini Bay have not been entirely reported. This study aimed to determine the fishing mortality rate and exploitation status of S. leptolepis in Tomini Bay by calculating Von Bertalanffy growth model parameters (L∞, K, t0) then plotting them into Pauly's empirical equation. The sampling was conducted monthly from April to September 2020 at Gorontalo City Fishing Port. Samples were collected randomly from five commercial fishing vessels shortly after the fishermen landed their catch at the fishing port. All fish samples were confirmed to be obtained by the fishermen from Tomini waters. The growth parameters of the samples were analyzed using FiSAT II based on Von Bertalanffy mathematical model. While the mortality and exploitation values were calculated manually using Pauly's equation. The study showed that the growth parameter values of S. leptolepis in Tomini Bay were 245.47 mm, 0.49/year, and -3.04/year for males, while 227.80 mm, 0.63/year, and -2.72/year for females separately for L∞, K, and t0. The total, natural, and fishing mortality rates were 3.06/year, 0.61/year, and 2.45/year for males and 0.99/year, 0.74/year, and 0.25/year for females. The analysis results showed that the female's natural mortality (M) was higher than the male. In contrast, the fishing mortality (F) and total mortality (Z) of male fish exceed the female. The exploitation value of males (E=0.80) was greater than that of females (E=0.26).

Abstract

Highlight ResearchThe chitinase production by Streptomyces sp. PB2 was studiedThe critical medium component for chitinase production were identifiedThe optimum medium composition for chitinase production was obtainedMedium optimization improved chitinase production by 6-fold increase in activityAbstractChitin is a polysaccharide compound composed of N-acetylglucosamine (NAG), which is linked by β-1,4-glycoside bonds. In producing NAG from chitin, enzymatic method using chitinase offer advantages compared to chemical degradation. Streptomyces sp. PB2 is a good candidate of chitinase producer which was previously isolated from shrimp pond sediment. However, optimization of chitinase production by Streptomyces sp. PB2 is required for large-scale production of this enzyme. This study aimed to find the optimal medium composition to increase the chitinase enzyme activity of Streptomyces sp. PB2 using the Response Surface Method. Initial screening was done to determine additional carbon and nitrogen sources in colloidal chitin broth suitable for increasing chitinase activity. Optimization of the medium composition was conducted using the Plackett-Burman design to determine the critical components in the colloidal chitin broth medium and continued by Box-Behnken model to optimize the concentration of the medium components. Chitinase activity was obtained by measuring the amount of reducing sugar (NAG) released from enzymatic reaction using DMAB reagent by means of spectrophotometer. The medium components showing high contribution in increasing chitinase activity were K2HPO4, colloidal chitin and peptone, with the confidence level value of 0.66, 0.48, and 0.38, respectively. The Box-Behnken model analysis shows that the combination of K2HPO4 0.007 g/ml, colloidal chitin 1.5 g/ml and peptone 1.5 g/ml in colloidal chitin broth are the optimal medium for Streptomyces sp. PB2, resulted in chitinase activity of 0.0125 U/ml. The increase of 6-fold in chitinase activity was achieved in this study.

Abstract

Highlight Research AbstractChitin is a natural compound found abundantly in shrimp shells. Chitin can be degraded to produce N-acetylglucosamine, which has wide applications in the food and pharmaceutical fields. Fermentation using chitinolytic microorganisms can be used to produce N-acetylglucosamine from shrimp shells' chitin. One of the strong chitinolytic bacteria that was isolated from previous research was Providencia stuartii. To provide better stability and efficiency in fermentation, P. stuartii cells were immobilized using entrapment method in papaya trunk wood. The aims of this research were to determine the optimum papaya trunk wood size, ratio of papaya trunk wood and growth medium, as well as the optimum fermentation cycle to produce N-acetylglucosamine from P. vannamei shrimp shells using submerged fermentation method. The research used experimental method with treatment of different sizes of papaya trunk wood (1 x 1 x 1 cm3, 1.5 x 1.5 x 1.5 cm3, and 2 x 2 x 2 cm3), different ratio of papaya trunk wood and growth medium (1:10, 1:15 and 1:20), and 4 fermentation cycles. Results showed that papaya trunk wood with size of 1 x 1 x 1 cm3 and ratio (w/v) of 1:10 could immobilize 87.08±2.05% of P. stuartii cells and produce the highest N-acetylglucosamine concentration, which was 238177.78±3153.48 ppm. The highest N-acetylglucosamine production was obtained from first fermentation cycle and decreased over the last three cycles, but still produced high concentration of N-acetylglucosamine. Therefore, it is possible to perform continuous N-acetylglucosamine production from shrimp shells using P. stuartii cells immobilized in papaya trunk wood.

Abstract

Highlight ResearchDipped lamp technology with CCTV (UFLPlus) to catch fish was designed in such a way that the placement of components contained was integrated, water-proof, and having a good light distribution.The existence of a CCTV in new innovated UFLPlus that can record events in the water and greatly assist fishing activities of fishermen on passive fishing gear such as boat charts.UFLPlus worked well to increase the number of hauling every night of fishing (from 20-30 kg to 50-60 kg per hauling).AbstractThe usage of underwater immersion lights outfitted with CCTV is a technological innovation that is expected to solve the inadequacies of the acoustic work system while also improving the existing underwater immersion light work system. Underwater Fish Lamp Plus (UFLPlus) technology can attract attention and directly monitor the condition of fish in the sea from the boat. The purpose of this study was to understand how the UFLPlus was designed and constructed; to test its performance using lamplight, waterproof, and immersion tests; to learn how the light distribution pattern is formed; and to learn the state of the catch. The study was separated into two phases: the design and fabrication of UFLPlus, and numerous laboratory-scale experiments and outdoor trials with boat lift net fishing gear. The results reveal that UFLPlus performed effectively in the field after all of its physical components were tested in the laboratory, and that the values of light intensity and light distribution patterns are still in accordance with the level of adaptation to light reception on the fish retina. During the trial catch, 62 kg of anchovy (Stolephorus sp.), 27 kg of ponyfishes (Leiognathus sp.), 32.5 kg of fringe-scale sardinella (Sardinella fimbriata), and 17.5 kg of yellow-stripe scad (Selaroides leptolepis) were caught. UFLPlus was capable of functioning as an underwater immersion lamp that attracts fish attention and directly monitors the arrival of fish in the water in the fishing area.

Abstract

Highlight ResearchPrices are often a signal for producers to produce or market products, including the price of tuna.Four price behaviors, namely trends, seasonal variation, variability and instability, and market integration, are important to study in designing business development plans.Tuna prices in Indonesia tend to have a statistically positive trend.Tuna prices tend to be stable, or do not have high variability, throughout the observations and indicate a low price risk.The price of tuna fish in each port is formed independently and is not influenced and influences each other between the markets observed.AbstractPrices of agricultural and fisheries products have always been a concern not only by producers and consumers but also by the government in designing policies to control and stabilize these prices to protect the poor. Therefore, a study of price behavior is crucial to be scrutinized more deeply and comprehensively. This research is aimed at examining and analyzing tuna (Thunnus spp.) price behavior in terms of their seasonal, trend, variability, and instability behavior as well as their market integration. For this purpose, monthly data of tuna prices from 2011:1 to 2019:12 in five tuna production centers (provinces) in Indonesia, including North Sulawesi, West Papua, Aceh, North Maluku, and Bali, at the national level were applied.  It was found that tuna prices have a positive trend and are statistically significant, excluding in West Papua. The study also found that price variability and instability were insignificant during observations. The study also concluded that the tuna price in every single province in Indonesia is formed independently.

Abstract

Highlight ResearchThe author mentioned 2 highlights from their results research  Nano-chitosan has the best susceptibility to bacterial strains of E. coli, S. enteritidis, L. monocytogenes, B. cereus and S. aureus.Nano-chitosan showed higher degree of inhibition than that done by chitosan. AbstractThe COVID-19 pandemic has impacted the fisheries sector, a decline in exports and fishermen's income caused by the disconnection of the marketing chain due to lockdown implementation in several export destination countries. Fish is a source of protein and as perishable goods, it experiences quality damage due to spoilage, commonly caused by hampered distribution of catches. Natural preservatives are needed to preserve catch so it won't get spoiled and can be accepted by consumers in suitable conditions for consumption. This study aims to evaluate the particle size of nano-chitosan and determine the effectiveness of nano-chitosan spray with different concentrations as a natural preservative in caught fish. This research method begins with making chitosan through 3 stages: demineralization, deproteination, and deacetylation. Chitosan was made into nano-chitosan with various concentrations of 3:1, 4:1, and 5:1 using ionic gelation. Nano-chitosan underwent several tests, including PSA, antibacterial activity by disc diffusion, organoleptic, and the effectiveness of preservatives. Antibacterial activity of nano-chitosan was able to inhibit Bacillus subtilis at three different concentrations, the potential to inhibit Escherichia coli was optimal at 5:1 treatment. The effectiveness of nano-chitosan preservative bacteria inhibition at three different concentrations proved to be sufficient to be used to extend shelf life and ensure the safety and quality of fishery products. The best concentration of nano-chitosan was 3:1 treatment. Nano-chitosan spray from crab shell waste has good antibacterial activity and preservative effectiveness. It could serve as an antibacterial agent and natural preservative for fishery products during the COVID-19 pandemic.

Abstract

Highlight ResearchAfter bleaching disturbance and Acanthaster planci outbreaks, herbivore fishes species were dominated in MRP PiehThis explains the marine recreational activities in utilization zone MRP Pieh have no impact on reducing fish biomassAfter disturbance in MRP Pieh shows the coral reef fishes still endurance on bleaching event, and Acanthaster planci outbreak after disturbance in MRP Pieh shows the coral reef fishes still endurance on bleaching event and Acanthaster planci outbreak. However, the composition of corallivorous has decreased but has been an increase in herbivorous and carnivorous fish populationsAbstractPieh MRP encountered non-anthropogenic phenomena, precisely massive coral bleaching in 2016, 2017, and massive predators from Acanthaster planci outbreaks in 2018. This study aimed to understand the pattern of coral reef diversity in the core zone and utilization in the MRP area and compare it to non-MRPS locations that accept the same non-anthropogenic pressure conditions. Coral fish sampling using a UVC is categorized into three zones: the core zone, the utilization zone, and outside the MRP area. 8 Families of coral reef fishes were counted based on categories of level function in ecologies and economy. Taxonomic distinctiveness estimates were calculated mathematically for each sample, including species richness and taxonomic diversity were compared among zonation area. Pearson's Coefficient Correlation Matrix was used to measure the correlation relationship between zonation areas. There are 91 species of fish and 3002 individuals found. The richest family in the MRP Core Zone and MRP Utility Zone was Acanthuridae with 20 species and non-MRP has a lower species richness and abundance of fish communities. The dominant species in Pieh MRP was Ctenochaetus striatus with average abundant per site (21.3 ± 7.62, n = 3). Acanthuridae represents 55.98% of the total biomass in MRP-Core Zone, 63.13% in MRP-Utility Zone, and 41.55% in Non-MRP Area. This study showed the number of species and populations from corallivores fishes have decreased but has been an increase in herbivorous and carnivore diversity. The diversity indices (H') and ENS also shows no differ significantly between zonation.
