Abstract

Chinese consumers prefer to purchase fish that have only recently been killed. The supplying of live fish is routinely delivered by water. However, the traditional transportation of live fish with water results in small volume of transportation and may cost prohibitive. Therefore, cold anesthetized waterless live fish transport is considered an alternative and promising strategy, since this is likely to demand less energy with large freight volume. This paper aims to develop an intelligent traceability platform based on HACCP system that integrates wireless monitoring and quality control models to improve the quality control and safety transparency in waterless fish transportation. In this research Chinese sturgeon is taken as experiment subjects for long-distance transportation. Oxygen change model is established as a life-sustained key factor by hybrid prediction method can optimize fish survivability. Survival prediction model is also designed for improvement of live delivery quality with minimum stress accumulation under precise temperature condition. For tracing function evaluation, the QR Code combined with existing EPC traceability technology enables users to expediently query and quickly trace the safety transport information from aquaculture to markets. To demonstrate the automatic monitoring and intelligent traceable management in this platform, sturgeon delivery experiments have been evaluated and analyzed. The results illustrate this system can reduce the potential risks, implement quality control with high survival results, and improve the live fish transport volume at low-costly. In brief, application of this smart platform will provide an effective, suitable technical reference for aquatic enterprises to follow, and help them to adjust the waterless transport techniques for the other types of aquatic products.

Introduction

Live aquatic products marketing is regarded as value-adding processes because live aquatic products obtain substantially higher prices, lower processing costs and the minimal governmental regulations compared with fresh chilled or frozen product. In China, consumers prefer to purchase fish that have only recently been killed, because in Chinese culture freshly killed fish is believed to bring vigorous to the body and has a delicious flavor than dead fish. It is indicated the live fish sales have rapidly expanded and were estimated to be 140 million tons at the 2016 year in China, also proves that live aquatic product sales price is 5–10 times higher than chilled and frozen aquatic products (Ghughuskar, 2004, Piedrahita, 2000, Selset, 2015, Tomasso, 1988, Walters, 1994).

There are two conventional live fish transport strategy - namely closed containers and open containers delivery (Mccarthy, 1982, Mishra, 2015). The closed container is a sealed equipment in which all the requirements for survival are the self-contained and life-supported system. The open system consists of water-filled containers in which the necessary conditions for survival is supplied continuously from outside facilities. However, fish transportation systems by water come at a high price and energy consumption due to the cost of water weight freight, temperature, oxygenation or aeration maintaining (Pérez, 2015). The use of cold as an anesthetic in fish waterless transportation is considered as a green transport strategy since this not only increase stocking density, but also it reduces metabolism and oxygen consumption (Zhang, Fu, Xiao, Zhang, & Li, 2017a). If low temperature is to be used as an anesthetic condition during the waterless live fish transportation, special considerations are required. On the one hand, maintenance of temperatures within a suitable range would be a precise quality control measure during the long-distance delivery. On the other, the oxygen concentration, as well as carbon dioxide accumulation, are needed to be focused on during the whole transport and gradual recovery stages after waterless delivery. It is believed that the solution of oxygen content problems—an adequate oxygen supply—would be essential to the development of an efficient waterless transport strategy (Zhang, Zhang, Nga, Liufeng, & Yu, 2018). Recent researches illustrate the technology can eliminate the use of water which consists of 75% of the weight (Mi et al., 2012, Salin, 2005). This green delivery strategy (Samet et al., 1996, Zeng et al., 2014) may improve the survival result with minimum stress changes and prevent stiffening for better meat quality, which is widely used in the live delivery for fish, shrimp, crab, and shellfish.

Although waterless transportation is considered to have the advantages of high volume of transportation and low carbon, HACCP process control is still lack of research. Live fish delivery involves capture, loading, transport, unloading and temporary culture, which can induce large stress responses for lack of oxygen, vibration, suboptimal temperature (Harmon, 2009, Manguya-Lusega, 2011, Reed, 2003). Although, live fish in a dormant state suffer no shock and have little likelihood of suffering stress (Balamurugan et al., 2016, Tacchi et al., 2015). High mortality rates and relatively short survival times are the main issues of the problems with live fish transportation. In summary, in every stage of live transportation, HACCP process control will reduce the potential hazardous events occurring. The stress level and survival of live fish delivery largely depend on the continuous HACCP concerned quality control to guarantee high survival results.

Traceability based on IoT technology (O-Marchante et al., 2014, Rodríguez-Jacobo, 2016, Wang, 2008) is an effective management tool integrated with HACCP to assist users in case of occurring food quality issues through the identification and comprehensive monitoring. Effective micro-ambient management ensures the freshness of aquatic products along the whole chain (Aung and Chang, 2014, Kim et al., 2016, Pizzuti and Mirabelli, 2015, Storøy et al., 2013). Although food traceability system is mature and widely-applied in other fields. However, the traceability system of the waterless transport and its HACCP control is not yet perfect. The current developed traceability approach that is used in fresh aquatic products transportation prove themselves can be easily adapted to the different aquatic supply chain by integrated wireless sensor network (Xiao, He, Fu, Xu, & Zhang, 2016), stress bio-sensing (Wu et al., 2015, Yonemori et al., 2009, Yoneyama et al., 2009, Zhang et al., 2017), RFID (Chen et al., 2014, Juarros, 2009, Li, 2015, Manzanares-Lopez et al., 2011, Trebar et al., 2013), QR (Kim and Woo, 2016a, Muradzikwa et al., 2014, Seine et al., 2004). However, the traditional traceability technologies are not directly adopted for waterless fish transportation due to the lack of dynamic ambient parameters acquisition and the intelligent adjustment. Therefore, a traceability system that is based on EPC technology, QR-code and it builds a wide range of traceable management is proposed by this research.

Generally, this research aims to develop an effective traceability system for waterless live transportation of Chinese sturgeon by integration of ambient sensing and quality control model to guarantee the fish vitality and survivability and it consists of 4 sections. In the first section, the drawbacks of the live fish transport in water and waterless dormant fish transport as a promising alternative delivery strategy are introduced. Next, the processing and materials of waterless fish transportation are developed to support optimized live transportation and the HACCP concerned quality control models as well as traceability system design are proposed for effective traceable management. Dynamic monitoring, analysis, and prediction of key points in HACCP system are discussed in section 3 by improving the monitoring and quality control under the micro-ambient conditions, the traceability system is amply designed to realize the well-suited tracing for the whole live fish supply chain. Finally, the conclusion of this research and the implications for future work are presented in section 4.

Conclusions

Traditional live fish transportation is high cost and lack of hazard analysis critical procedure control which greatly restrict the development scale of the live fish supply chain.
