Aquaculture is a global-scale industry providing sustainable production of protein-rich foods required to feed the growing world population. Microalgae cultivation in aquaculture bioreactors can exude extracellular polymeric substances leading biofouling culture infrastructure and increased algal disease risk. A structure–behaviour relationship was developed by examining how surface wettability...

Biofouling, the accumulation of organisms on wetted surfaces, is a ubiquitous challenge for 12 submerged anthropogenic marine structures that can result in reduced efficiency, increased fuel 13 consumption, and greenhouse gas emissions from vessels. In addition, it causes weakening 14 corrosion maritime infrastructure, detrimental effects to aquaculture, translocation harmful 15 non-indigenous ...

Large-area, artificial floating marine litter (FML) targets were deployed during a controlled field experiment and data acquisition campaign: the Plastic Litter Project 2021. A set of 22 Sentinel-2 images, along with UAS ancillary measurements acquired. Spectral analysis FML natural debris (wooden planks) was performed, spectral comparison separability between other materials such as mucilage p...

Novel attempts to optimize the design and requalification of offshore structures draws attention importance updating information about environmental forces. One important steps or re-assess is re-evaluation/evaluation bio-colonization’s effects. This paper presents a review studies that considered biofouling in marine/offshore structures. Most previous researchers conducted effects as surface r...

Invasive, non-indigenous ascidians have been a significant biofouling problem for the aquaculture industry in Nova Scotia and Prince Edward Island since the mid-1990’s. The problematic species in Atlantic Canada include Styela clava, Ciona intestinalis, Botryllus schlosseri and Botrylloides violaceus. Newfoundland harbour surveys that we have performed over the past three years revealed the pre...

Several compact sampling platforms have recently been developed or are gaining widespread use in Naval operations and oceanographic research. In addition to limited sensor payloads, many of these platforms are autonomous and intended for extended deployments. Sensors compatible with these platforms must therefore be compact, low power, and able to accommodate effective anti-biofouling measures....

The novel liquid-infused membranes have been shown to mitigate membrane biofouling. Here, the long-term stability of these tested and analyzed using bacterial growth curve models.

Biofouling is one of the major issues in the power industry using seawater for cooling and other purposes. Presence of biological organisms such as bacteria and algae that could foul pipes and expensive equipments need to be managed from economical and safety point of view. Generally, the biofouling problem is aggravated in hot climate regions. Various means of disinfection processes are availa...
