“…Approximately 70% of total fishes in the landing center were handled by supplier who had to pay a significant amount of commission to the wholesalers for selling the products ( Rabbani et al., 2017 ). Composition of the marketing channels found from the present study is similar to several previous studies (Gowsalya et al., 2019; Grema et al., 2020 ; Roy et al., 2020a ; Mebrate and Worku, 2020 ; Uba et al., 2020 ). It is needless to say that fishes from the nearby water resources have to pass shorter distribution channel, their price in wholesale and retailer are comparatively lower; however, their consumer demand is high in the study area.…”

“…It is well established that fish provide not only protein and fatty acids, but also vitamin A, vitamin D and a number of trace elements [2]. Owing to the internal and inherent features, such as the brittle muscle tissue, the activity of endogenous protease, as well as improper treatment methods and storage conditions, fish are inclined to corrupt and produce substances threatening human health [3].…”

Affected by micro-organisms and endogenous enzymes, fish are highly perishable during storage, processing and transportation. Efficient evaluation of fish freshness to ensure consumer safety and reduce raw material losses has received an increasing amount of attention. Several of the conventional freshness assessment techniques have plenty of shortcomings, such as being destructive, time-consuming and laborious. Recently, various sensors and spectroscopic techniques have shown great potential due to rapid analysis, low sample preparation and cost-effectiveness, and some methods are especially non-destructive and suitable for online or large-scale operations. Non-destructive techniques typically respond to characteristic substances produced by fish during spoilage without destroying the sample. In this review, we summarize, in detail, the principles and applications of emerging approaches for assessing fish freshness including visual indicators derived from intelligent packaging, active sensors, nuclear magnetic resonance (NMR) and optical spectroscopic techniques. Recent developments in emerging technologies have demonstrated their advantages in detecting fish freshness, but some challenges remain in popularization, optimizing sensor selectivity and sensitivity, and the development of algorithms and chemometrics in spectroscopic techniques.

“…The aquatic food safety tracing management is constructed without manual intervention, which fundamentally prevents the possibility of data falsification (Grema, Kwaga, Bello, & Umaru, 2020). The IoT and blockchain‐based technology in our constructed systems will bring convenient automation, reducing management costs, diminishing the possibility of counterfeit (Fernandez‐Carames & Fraga‐Lamas, 2018).…”

This study puts forward a novel frozen aquatic product traceability system (BIOT‐TS) that based on blockchain and Internet of things (IoT) technology, which can alleviate the drawbacks of current tracing management during cold chain logistic, such as the weak security performance, inefficient centralized data management as well as the easy‐tampered traceability information. The proposed system possesses the advantages of decentralization, safety, reliability, and tamper‐proofing when it compares with traditional tracking technology. It is particularly suitable for multi‐stages tracking management of cold chain logistics from aquaculture, production, logistics, and circulation to sales. In terms of such blockchain‐IoT‐based technology, the system is deployed and evaluated with the case of frozen turbot (Scophthalmus maximus) that is circulated and sold under the background of e‐commerce cold chain logistics. It can significantly improve the quality and safety of the frozen aquatic product by using smart contracts, consensus strategy, and data on‐chain verification technology. The overall involved participants can share more reliable tracing information after adopting this tracing system. Furthermore, the performance of this hybrid tracing technology has been evaluated by the operations of on‐chain process and tracing queries through the real experiments, and has testified to be effective. Therefore, the application of this system is beneficial for the improvement of the aquatic food logistics industry and ensures credit in its ecosystem. Practical Applications The blockchain‐IoT‐based frozen aquatic product traceability management is one of the most promising technologies that possess the advantages of tamper‐proof, transparent, and irrefutable transactions combined with distributed monitoring and tracking functionalities. Through the decentralized data management, smart contract, and mechanism of consensus, the traceability information is partitioned and encrypted storage, which can be used for government supervision and consumers' retroactive queries. This novel frozen aquatic food product tracing technology can fundamentally improve the reliability of quality tracing applications and make the closely related tracing management more transparent, secure, and efficient.
