The project seeks to assess water quality through a combination of multispectral imagery and cloud data processing. With global temperature increase, sea-level rise and water quality degradation, the marine environment has been impacted severely over the last few decades. Remote [...]
The attachment point of fish farming nets to the floatation structure, referred to as the Collar Tie, has been identified as a weak point for particularly for areas where pens are deployed in high energy environments. With industry partner [...]
Recently, New Zealand King salmon aquaculture has proposed to move their salmon farming to offshore sites. This means the salmon, which have been genetically selected for current farming conditions, will be exposed to high energy environments. This PhD project, [...]
Offshore fish farming will become an inevitable trend for high productivity and low pollution in the future. For deep-sea fish cages, there are a few technical challenges that need to be overcome. First, there are limited information and references [...]
This project will investigate the prospect of using acoustic sensing devices to monitor and estimate production in salmon and macroalgae production sites, both land-based and offshore. In order to do this, acoustic systems will be positioned in-situ to collect [...]
In 1975, the beach-cast seaweed industry was established on King Island, Tasmania, with the formation of Kelp Industries Pty Ltd. Beach-cast Southern Bull Kelp (Durvillaea potatorum) is collected from beaches, dried, and shipped offshore for alginate extraction and the [...]
Offshore seaweed aquaculture presents significant opportunities to coexist with other aquaculture ventures (e.g., finfish farming) and offshore energy developments, thanks to its ability to attenuate hydrodynamic energy and reduce hazardous ocean conditions. However, current predictive models are limited, often [...]
In December 2024, Martin Ziarmal began his interdisciplinary PhD on Floating Urban Extensions, partially supported by a BE CRC scholarship for the first six months. During this period, he is conducting a literature review on various floating foundations and [...]
The salmon industry in Tasmania is economically significant, valued at over $1 billion AUD. This growth is partly due to the gains made from selectively breeding for desirable traits over the years. However, selective breeding for feed efficiency has [...]
As part of the effort to advance offshore aquaculture, various mechanisms are being explored. This study focuses on the structural analysis of the SeaFisher, a proposed structure for aquaculture in Australia. The SeaFisher utilizes high-density polyethylene (HDPE) and glass [...]
Canopies of seaweed, as formed in seaweed aquaculture, have the potential to attenuate hydrodynamic energy from waves and currents by exerting drag forces on the water column and thereby may offer co-benefits to adjacently located marine infrastructure such as [...]
Giant kelp forests rank among the planet’s most productive and biodiverse ecosystems, providing a habitat for thousands of species. Kelp plants capture significant amounts of carbon during their growth and play a vital role in mitigating climate change. Additionally, [...]
The Tasmanian Atlantic salmon industry is facing increasing challenges due to the impacts of climate change, these pose significant threats to local industry as well as to global aquaculture. Sub-optimum water temperature and dissolved oxygen are the two major [...]
This Project focuses on improving the ability of unmanned vehicles (UUVs) to accurately determine their position and orientation while operating in offshore aquaculture environments. Reliable localisation is essential for enabling autonomous underwater operations. However, this remains a significant challenge [...]
The objective of this project (2.21.003) is to provide fundamental information needed to further develop a Durvillaea (Bull Kelp) aquaculture industry in New Zealand. This project will be primarily focus on the endemic species D. poha and D. antarctica. [...]
The Australian seaweed industry is currently limited despite an increasing demand for seaweed products. One product of high demand is alginate-saturated kelp which is utilised by agricultural, food, medicinal and pharmaceutical companies. Because of low local production, most of [...]
Poor skeletal health poses a risk to fish welfare and performance, particularly in physically demanding offshore and high energy farming environments, where the finfish aquaculture industry are actively planning to expand. For fish to survive and thrive in these environments [...]
A relocation of coastal, shallow-water fish farms into deep offshore waters benefits the industry in three ways: it puts fish into colder water it dilutes the rain of organic waste that reaches the seafloor underneath and in the vicinity [...]
Biofouling, the growth of unwanted organisms on submerged surfaces, is a big issue in the aquaculture sector with large direct costs of cleaning and indirect costs of reduced animal welfare and infrastructure damage. My project will aim to introduce [...]
The design and analysis of offshore structures is associated with a unique set of challenges that require knowledge of various engineering disciplines. The goal of this project is to develop an integrated numerical modelling framework that can yield optimal [...]
This project aims to exploit filter feeding bivalves as a natural eDNA sampling medium to determine the presence of some of the most crucial pathogens, including algal and bacterial blooms and parasites such as amoeba, in the Tasmanian aquaculture [...]
The project will contribute to quantifying coastal marine seafloor ecosystem functioning under proposed offshore aquaculture activities. Working with the team on the larger project ‘A novel approach to measuring the depositional footprint of the Blue Economy’ the PhD will [...]
