“…Hairtail ( Trichiurus haumela ), belongs to the order of Perciformes, family of Trichiuridaeis , is one of the most economically and ecologically important fish species in the Yellow Sea and East China Sea (Sun, Chen, & Fu, 2020; Yong, Cheng, & Chen, 2009; X. Zhao, 2006), as well as southern seas of Korea (Hwang, Yoon, Kang, Cha, & Lee, 2017). In recent years, hairtail becomes more and more popular in Asia with its abundant fish stocks due to its delicious taste and peculiarly nutritional benefits (Chakraborty, Aranishi, & Iwatsuki, 2010; Luan, Sun, Chen, Wu, & Hu, 2018; Luan, Wang, & Hu, 2018).…”

This study aimed to investigate the effects of liquid nitrogen freezing (LNF) in long‐term frozen preservation of hairtail. Fresh hairtail was frozen by liquid nitrogen or cold air and stored at −20°C or −80°C for up to 120 days. The contents of carbonyl, TCA‐soluble peptides, AG and NAG enzyme activities increased, whereas Ca2+‐ATPase, Mg2+‐ATPase activity and the contents of sulfhydryl group decreased with the storage time increased. The activities of cathepsin B and B + L could be inhibited by low temperatures in the initial 40 days. However, the inhibition gradually weakened as the storage time increased. Protein surface hydrophobicity increased and reached a peak of 480.23 on day 60 with a subsequent fluctuant decrease. The α‐helix and β‐sheet structures of myofibrillar protein decreased, while the β‐turn and random coil structures increased. And the texture degradation occurred in all the tested four groups. The muscle fibers begun to break in cold air freezing (CAF) group after storage of 60 days. After a storage period of 120 days, large holes appeared in meat sample of CAF group. The muscle fibers of the LNF groups were kept much more complete than that of the CAF groups, indicating the advantages of LNF. Practical Application In this study, the advantages of liquid nitrogen freezing (LNF) on the quality of hairtail during long‐term frozen preservation were showed by enzyme activity, protein structure and tissue structure. Although LNF causes inevasible damage to the fish meat, the ice crystals during freezing were rather small and distributed homogenously due to fast freezing rate. Thus, the mechanical damage to muscle was much lower than that of the cold air freezing (CAF), showing great advantages of LNF. Liquid nitrogen was recommended for pre‐frozen of hairtail before frozen storage to maintain the quality of hairtail. These results could provide theoretical guidance for the applying of LNF on the hairtail processing for the quality maintenance of hairtail whilst aiming to get maximum nutritional benefits. This knowledge can also be widely applicated in other fishery products preservation.

Indonesian Fisheries Management Area (FMA) 572 situated in the Indian Ocean, includes the coastal waters of Bengkulu City, has great potential in terms of pelagic and demersal fisheries. However, the exploitation of these fisheries resources has been intensified due to the growing demand for human consumption. Unfortunately, information related to the susceptibility and productivity of fisheries resources in this area is still negligible. The purpose of this study was to determine the level of vulnerability to potential fishery impacts of several pelagic and demersal fisheries in FMA 572. The study was conducted in Bengkulu City from July to December 2019. Analysis of the productivity and susceptibility level of the fisheries used several productivity and susceptibility parameters through the Productivity and Susceptibility Analysis (PSA) method. The results of the study revealed that the vulnerability level of yellow stripe scad (Selaroides leptolepis) was higher than that of other target fishes. However, in general, the vulnerability of pelagic and demersal fisheries to potential overfishing in FMA 572 was still low.
