Lindsay Hopper
Lindsay Hopper has been involved with the aquaculture industry for over 15years. Having completed a Masters of Applied Science in Aquaculture at the University of Tasmania, Lindsay has gained a comprehensive understanding of the many segments of the aquaculture industry, with practical and theoretical knowledge covering the wide range of species that make up this diverse and ever changing industry.
Lindsay grew up on a family owned dairy farm before going on to study at Tocal Agricultural College. This agricultural background has given Lindsay a good understanding of animal husbandry, which he believes is paramount for success in the aquaculture industry.
During this study at the local agricultural college, Lindsay developed an interest in aquaculture, which later grew into his lifelong passion. After obtaining the Advanced Certificate in Agriculture, Lindsay further pursued his interest in aquaculture by enrolling at the premier aquaculture study institution in Australia, The University of Tasmania. Six years of full time studies followed as he completed the Associate Diploma, Diploma, Post Graduate and Masters in Aquaculture.
In May 1997, Lindsay was employed by Aquasonic Pty Ltd to be part of the sales team. He is now the sales manager and heads an enthusiastic sales team. His current position involves working closely with farmers and research institutions, both nationally and internationally, including hands on installations, sizing, applying and general consultancy. His work covers virtually the entire industry, including all the commercially grown species in Australia and overseas, hatchery, grow out (indoor and outdoor) and the live seafood holding and public aquarium fields. Lindsay recently traveled to Indonesia where he installed some of Aquasonic's recirculation systems for the farming of Barramundi Cod, one of the most sort after marine species in the world. Lindsay's position also involves the acquisition of products and representing Aquasonic Pty Ltd at conferences and trade shows again on a national and international level.
The Presentation
Discover the Aero-Tube™ Oxygen Advantage. Aquasonic are pleased to introduce Aero-Tube™ Aeration Tubing, manufactured by Colorite Plastics, the next major advance in aeration technology. Aero-Tube™ continuous-bubble aeration tubing delivers oxygen in volumes that are unmatched by conventional systems, and at an energy cost that is often less than half that of other systems. There are many options for using Aero-Tube™, from tubing making up a diffuser, the hose itself and even a ready-made diffuser grids which can be made into a blower operated airlift system that is truly impressive. These ready-made “diffuser grids” are engineered to optimally use the Aero-Tube™. A single grid (60cm x 90cm) will transfer 1.21kg of O2 per hour (29kg per day). The performance of the same grid in seawater application is 2.5 times greater (resulting in 72kg O2 per day).
Field tests performed both here in Australia and overseas, have also proven that when these grids are applied in an “Airlift” configuration that they are more efficient and more cost effective to operate than paddle wheels. Doubling your oxygen transfer rate compared to paddle wheels when you look at horse power. So this means that effectively you can saving around 30% on power costs by using less horsepower. For example, where a pond might require a 2HP Paddle Wheel (rated at putting in around 1kg of O2 per hour, 48kg per day), you can alternatively apply a 2-Way Airlift Grid System where you only require a 1.2HP blower to operate it, plus you get an additional 10kg of O2 transfer per day (total O2 transfer of 58kg O2 per day). Not only power savings are achieved with using this form of aeration, I will show you how you can also achieve increased biomass, reduced FCR’s, reduced accumulated sediment and faster fish growth by using this simple aeration technique. Simple to operate, low maintenance, simple construction and can be self installed. You can purchase off the shelf units, or alternatively construct them yourself. Food, power, water quality, time to market are all factors that influence your costs of production and thus your profits. This aeration technology can be a part of your “tools of the trade” to help make profitability more of a reality. Lindsay will also highlight some other new products and innovations that will interest aquaculturists.
