Pilot Test for GPS and Beidou Dual Satellite Receiver System with Nautical Charts, Fish Finder and Automatic Identification System#

This project is a continuation of the Automatic Identification System pilot test aims to install new GPS and Beidou dual satellite receiver systems devices on small fishing vessels of less than 15 m in length to replace the traditional AIS devices in order to evaluate the effectiveness of the 4-in-1 device on safety and fishing operations compared to the traditional AIS device. The new 4-in-1 system comprises of Cantonese automatic identification AIS, fish finder, GPS and Beidou navigation and nautical chart functions. The two navigation systems can operate in parallel to achieve better positioning and reliability.

Product Development of Nano Pearl Powder with Detoxification and Antioxidant Functions*

This project is a continuation of the project on product development of nano pearl powder aiming to study the protective effects of nano pearl powder on the detoxification of accumulated metallic toxins in the food chain, as well as the antioxidant properties of nano pearl powder extracts. Nano-scale particles exhibit unique structural, chemical, mechanical, magnetic, electrical, and biological properties. Nano-medicine has gained significant attention in recent years as its nanoscale structure can be encapsulated or attached to therapeutic drugs and precisely delivered to target tissues by controlled release. The application of nanotechnology in biological science and disease prevention and treatment will be an emerging field in future development of drugs and health products.

Cuttlefish Mariculture Pilot Project in Hong Kong Waters

This is a pilot project aims to assess the feasibility of cuttlefish mariculture in Hong Kong waters, increase survival rate and reduce cultivation cost in order to enhance fishermen’s income, improve fishermen's culture techniques and encourage fishermen and the young generation to transit from traditional capture fisheries to mariculture.

Pilot Scheme for Scientific Release and Breeding of Fish Fry in Hong Kong for Stock Enhancement

This project aims to enhance the marine environment and fishery resources in Hong Kong waters. Due to the excellent results from the previously implemented pilot fish fry release program by the Hong Kong Airport Authority, the institution hopes to learn from this initiative by breeding and raising fish fry in local aquaculture areas. Once the fish fry are grown into juvenile fish, they will be released into Hong Kong's waters to increase fish populations and enrich fishery resources.

Seabed Restoration Plan for Aquaculture Areas

The project aims to improve the marine environment around fish farming areas. The project team proposes to increase oxygen supply at the interface between the water column and the seabed, particularly in areas where waste accumulation is most severe, to accelerate the natural decomposition process. Given that nanobubble technology is increasingly applied worldwide but has not yet been used in Hong Kong's fish farms. In this project, the team will apply and evaluate such technology to restore the sediment layers beneath Hong Kong's marine fish farms so as to determine whether such technology can be used by existing fish farms in Hong Kong to restore the seabed successfully. The goal of the project is to improve water quality and reduce exposure to pathogens associated with sediment under fish cages. This system will be applicable to all marine aquaculture farms where fallowing is not feasible, especially fish farms that have experienced disease outbreaks and reduced dissolved oxygen levels.

Hong Kong Castle Peak Bay Fisheries Resource Enhancement and Marine Biological Resource Restoration in 2024

The project aims to prioritize ecological conservation, adhere to the principles of comprehensive marine ecological restoration, and scientifically and rigorously formulate and implement the release of multiple ecological species — fish, shrimp, crabs, and shellfish — in the waters of western Hong Kong. This will serve as a benchmark for marine stock enhancement and resource restoration in Hong Kong’s waters. The project highlights the ecological functions of stock enhancement, increases fishery biological resources in the marine area, restores marine fishery communities and food web structures, and rehabilitates marine ecosystems. Additionally, it seeks to encourage public participation in the conservation of fishery resources, raise public awareness of marine care and the sustainability of fishery resources, and achieve the goal of jointly safeguarding Hong Kong’s marine ecology.
