Introduction

Aquaculture has been going through a revolution. Anyone could easily forget that it is quite a new industry, as most of its farms came into existence in the late 20^th century. Fortunately, the emergence of aquaculture has had positive outcomes. Today, aquaculture is responsible for over 50% of global fish consumption, making a significant contribution to our seafood supply. In addition to establishing a new industry, aquaculture holds the potential to address the challenge of feeding a growing population. As arable land remains limited and population numbers continue to rise, seafood production offers a sustainable solution for ensuring a reliable food source.

In 2018, the total production of fishery products, including aquaculture, reached its peak at around 179 million metric tons. Out of this total, around 156 million metric tons were allocated for human consumption, whereas approximately 22 million metric tons were primarily used to produce fishmeal and fish oil. Between 1961 and 2018, the per capita consumption of fish food increased from 9.0 kg to 20.5 kg, with an average annual growth rate of about 1.5%. Aquaculture now accounts for 46% of the total fishery product consumption, or 52%, when excluding non-food uses.

Managing sustainable practices, complying with local regulations, and ensuring quality across the seafood supply chain can be challenging, leading to consumer doubts about product quality. To tackle this issue, regulators, food processors, buyers, suppliers, and customers must have a dependable mechanism for exchanging precise information regarding the fish. A digital traceability solution, such as blockchain, offers a potential solution to this problem by creating an immutable record of every aspect of the fish’s journey, from its origin as an egg to its presence in the fishmonger’s case.

Aquaculture involves farming aquatic organisms such as fish, Mollusca, crustaceans, and echinoderms. In this process, certain interventions are made to enhance production, such as stocking, feeding, and protecting the organisms from predators. Aquaculture implies ownership or contractual rights over the cultivated stock, primarily for livelihood and business purposes. Harvesting aquatic organisms owned throughout their rearing period is considered part of the fisheries industry. Aquaculture production involves cultivating aquatic organisms for consumption as raw materials for processing or trade. It also includes the production of fish and hatchery outputs, which are measured by numbers rather than weight.

Their purpose is to track the journey of these products throughout the value chain, ensuring transparency and accountability in terms of origin, production practices, and quality.

Traceability

Traceability is crucial in ensuring the safety and quality of aquatic organisms in the aquaculture supply chain. It is a component of food safety management systems, essential for meeting national and international requirements and accessing specific markets like the USA, the EU, and Japan. Traceability can be mandatory or voluntary, depending on government or private sector initiatives. Regardless of regulatory requirements, traceability has become a standard practice in the international trade of fish and fish products.

Blockchain

Blockchain is a decentralized, tamper-resistant digital ledger or distributed database that facilitates the secure and transparent recording, verification, and storage of information. It works through a network of computers, or nodes, where every node has a copy of the entire chain of blocks. Each block contains a list of transactions or data that, once added, becomes almost impossible to change or manipulate. Blockchain’s immutability is enabled through cryptographic hashes and consensus algorithms.

RFID tags are used in fish farming to track and monitor fish. These tags contain radio frequency identification technology that allows fish farmers to collect data on the fish’s location, behavior, and health status. This information helps in managing fish populations and optimizing feeding and environmental conditions.

GPS tracking is employed for shipping containers in the aquaculture industry to ensure the secure and efficient transportation of seafood products. Containers can be tracked in real-time using GPS devices, providing accurate information on their location and movement. This helps in improving logistics, reducing delays, and ensuring the freshness and quality of the products.

Blockchain technology is utilized for data storage and sharing in the aquaculture industry. It provides a decentralized and tamper-proof system for recording and managing data related to fish farming, supply chains, and certifications. Blockchain enhances transparency, traceability, and trust among stakeholders, ensuring the authenticity and integrity of information.

Cloud-based aquaculture management software is a digital solution that enables fish farmers to streamline their operations and enhance productivity. This software is hosted on cloud servers, allowing farmers to access and manage data, such as water quality, feeding schedules, inventory, and production records, from anywhere with an internet connection. It facilitates better decision-making, automation of processes, and improved efficiency in managing aquaculture operations.

Overall, using these technologies contribute to the advancement of fish farming & traceability in aquaculture by enabling better tracking and monitoring of fish, efficient shipping logistics, secure data management, and streamlined farm management practices.
