Research and Application of Intelligent Management and Automation Technology in Marine Fisheries

2023-10-24

In Taiwan, pelagic fishery is facing growing challenges due to multiple impacts such as resource scarcity, aging workforce, labor shortage, rising management costs, and increasingly stringent international catch management measures. It is an urgent issue for the industry to establish energy-saving and labor-saving automated fishery technology through cross-sector integration.

The smart agriculture program has been implemented for 6 years in the marine fishery industry in response to the difficulties and expectations of the industry. Regarding the policy side, an important objective is the development of Electronic Monitoring System (EMS), which can automatically interpret catch records through image recognition. This technology saving reporting time and manpower by 80% is beneficial to relieve fishery observers’ workloads and achieves law enforcement and the multi-use of scientific data. On the industrial side, it is focusing on the development and promotion of energy-saving and labor-saving fishing equipment. For example, the “Intelligent LED Fish Lighting” has integrated LED lighting with trapping spectrum, self-diagnosis, and smart recording module, which can reduce fuel consumption by about 15%~20% and lamp failure risk compared with traditional fish collector lamps; the field test of “Saury Automatic Grading, Arrangement and Packing System” showed that each fish can be processed in about 1 second, and the introduction of this system has been saving USD15,000 labor costs for fishing vessels in 2020; the development of conservation-type fishing gear " The Juvenile and Trash Excluder Device (JTED)" for trawl fisheries can help fishermen to filter out bycatch and increase the value of their catches.

Through the development of technologies mentioned above and their promotion through the technology service platform of the Intelligent Fishery Industry Alliance, Taiwan's marine fishery industry will better meet the regulations of international organizations with the assistance of these labor-saving and energy-saving equipment. Technology allows fishery practitioners to improve production processes, and reduce fuel consumption and labor costs, thereby increasing fishermen's income and strengthening the competitiveness of pelagic fisheries, leading to the goal of the eco-friendly and sustainable fishing fishery.

Title

Introduction

The Juvenile and Trash Excluder Device (JTED) for Trawl

 The Juvenile and Trash Excluder Device (JTED) with a 15 mm bar spacing can successfully exclude non-target catch accounting for 25.8% of the total catch weight for trawling, which ensures retains most of the economic fish and Crustaceans. For the purpose of taking into account both fishermen's livelihoods and fisheries resource conservation, JTED is worth to be promoted.

 Intelligent LED Fish Lighting

 Intelligent LED Fish Lighting integrates three modules including LED lighting with trapping spectrum, self-diagnosis, and intelligent recording, which can reduce fuel consumption by 15%~20% and lamp failure risk compared with traditional fish collector lamps. In addition, a fishing decision-making system can be constructed with big data to facilitate the transfer of experience. So far, almost 95% of ocean saury fishing vessels have been equipped with the lighting. Squid fishing boats will also make adjustments to the lighting with reference to the successful experience of the saury industry.

Saury Automatic Grading, Arrangement and Packing System

 TSaury Automatic Grading, Arrangement and Packing System composed of several inclined rollers enables saury to be first categorized according to their size by sliding on the platform. After entering the automatic arrangement system, fish bodies can be identified through the camera, and the motor paddle will guide the saury with the same body direction into the packing area on both sides, which facilitate the boxing for fishermen.

Electronic Monitoring System (EMS)

 Electronic Monitoring System (EMS) with monitoring software including continuous recording and video storage functions can be applied to fishing vessels of different tonnages. The APP developed for the system is convenient for observers and operators to edit and replay the videos. Furthermore, through the image recognition function of the system, fishing operations and catches can be automatically recorded, such as catch timing and fish identification. This technology is still under development and is now on the field test.
