“…Nemipterus japonicus is widely distributed through the Indian Ocean and West Pacific. Ali et al (2014) analyzed the population resources in the Indian Ocean from 1986 to 2014, but not in the South China Sea. Similarly, although Siganus fuscescens, Terapon theraps, and Upeneus moluccensis occupy an important economic position in China's fisheries (Ma and Liu, 2006), the specific assessment of their resources has not been reported before.…”

The Beibu Gulf in China is rich in fish resources. However, only a small number of commercially developed fish stocks have been specifically assessed owing to limited data and expertise. In this study, 19 perciform fish populations in the Beibu Gulf were assessed using a length-based Bayesian biomass (LBB) estimator method, which is a new approach to evaluate a fishery’s status using length frequency (LF) data. The results showed that only 21% of the evaluated stocks were healthy and 79% were overfished. In particular, 26 and 21% of the assessed species had collapsed and were grossly overfished, respectively. Only 11 and 21% of the assessed species were slightly overfished and overfished, respectively. The ratios between the mean and optimum length (Lmean/Lopt) and between the mean length at first capture and the mean length, which maximizes catch and biomass (Lc/Lc_opt), were below one in 14 out of the 19 stocks, suggesting a truncated length structure and fishing of undersized individuals. The ratio of the 95th percentile length to asymptotic length L95th/Linf was close to one (>0.9) in 10 of 19 stocks, suggesting that at least some large fish were still present. Our research confirmed that the fishery resources in the Beibu Gulf were seriously overfished and provided evidence that LBB was an efficient method to evaluate the fishery resources. Fishery managers need to take specific measures to restore fishery resources.

This study aimed to determine the Development of Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes and if there were significant differences in the Development of Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes using three different proportions of ingredients per treatment in terms of aroma, color, flavor, texture and general acceptability. The present investigation employed experimental design to establish the level of acceptability of the Development of Spring roll using Wrapper with Threadfin Bream (Nemipterus Japonicus) Flakes. There are three treatments subjected for evaluation using a Researcher made Survey questionnaire. These were Treatments A, B, and C. There were fifteen (15) trained panels composed of faculty of NIPSC Ajuy Campus that were purposely selected to evaluate the product. The data gathered were analyzed using the mean, standard deviation and the Friedman’s Test (Freidman’s ANOVA). The criterion for rejection and acceptance of hypothesis was set at 0.05 level of significance. The study was conducted at NIPSC-Ajuy Campus, during the 2nd Semester of School Year 2020-2021. The findings were based on the data and the results of the analysis obtained were as follows: Treatment B with 150 grams of threadfin bream flakes was found to be “extremely acceptable” and comparable with the commercial spring roll wrappers (Treatment A) in terms of aroma, color, taste, texture, and general acceptability. No significant differences was found out in the acceptability of the Development of Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes in terms of aroma, color, taste, texture, and general acceptability. Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes has suggested retail price of P2.65 which is more than 100 % higher compared to the commercial spring roll wrapper with selling price of P1.00 per piece. Finally, it was recommended that continuous research and development shall be pursued in case commercialization of Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes is considered especially in the cost aspects. A feasibility study shall be conducted first before commercialization is pursued. Other pelagic fishes shall also be ventured and tested to fortify spring roll wrapper. Although results positive results in terms of acceptability, researcher shall look into possible ways to lower the cost of the product to ensure profitability. The Municipality of Ajuy along with the academic community and research authorities to take action on making researches that shall promote the utilization of pelagic fishes in the town. This actions shall enable the economic development of the town that can help resolve poverty and shortage of food in the Municipality of Ajuy. The said activities shall also promote entrepreneurial spirit especially the small and local businesses in the community

“…N. japonicus is a member of the family Nemipteridae , majorly caught throughout the Indo‐Western Pacific Ocean (Ning et al, 2015) and usually found in the depths of 5 to 80 m on sandy or muddy bottoms (Kalhoro et al, 2014) of coastal water. In 2015, the total production of Nemipterus species was around 650,000 tons (FAO, 2017).…”

Japanese threadfin bream (Nemipterus japonicus) minced meat foams added with methyl cellulose (MC) at a concentration of 0.5%, 1.0%, and 1.5% w/w with foam thickness of 0.5 mm were subjected to foam-mat drying (FMD) at two drying temperatures (70 and 80°C). The objective of this study was to investigate the drying kinetics of the minced fish meat foams at different drying temperatures and MC concentrations. The effect of FMD conditions on the physical properties of powdered samples was also investigated. The drying data were fitted to a selected thin-layer drying models based on moisture ratio. The Page model was found to be the best model (R 2 = 0.9930, χ 2 = 0.0005 and RMSE = 0.0202) to describe the drying curves of threadfin bream foams. The L*, a*, b*, and whiteness values of FMD fish powder were significantly affected by all the factors including the interaction (p < .05). An increase in particle size from 116.22 to 131.80 μm was observed as the drying temperature and MC concentration increased. The powder showed good-fair flowability and are within the acceptable range. Both drying temperatures yielded fish powder with satisfactory physical characteristics. Practical applicationsDrying is a method of food preservation that removes the water from the food. Using foam-mat drying, the minced fish meat is converted into fish powder at a lower drying temperature and shorter drying time. Mathematical modeling of the drying process of threadfin bream foams helps to predict the behavior of moisture removal from the foams and the process design, increasing the use of Japanese threadfin bream in the food industry. The fish powder obtained by this method has greater bulk density, which reduces packaging and transportation costs. The fish powder can be incorporated into other products to add value.
