New Open Ocean Aquaculture Cage Design

Open Water Systems Ltd. has spent the last 5 years designing,testing and patenting a 50′ X 50′ X 36′  2500 cubic meter steel submersible cage for the aquaculture industry.  The new cage, designed by a fish farmer with 12 years experience, was carefully planned to provide a reliable rugged rearing unit that was both fish and farmer friendly.  The cage can be operated at surface in the same fashion as traditional surface cages allowing purse seine harvesting, stock inventory and inspection WITHOUT the need of diving.  The cube design allows the entire net to be secured from top to bottom providing a consistant rearing volume in high current and when towing.  The upper hinged walkway is repeated at the base of the four 36′ deep spars allowing the continuous netting attachment points.  The rubber insert torsion hinge design absorbs any movements between the spars and walkways minimizing metal fatigue.  The lack of horizontal plannes allows wave energy to pass through the structure minimizing the forces on the structure.

Other advantages include:

1.) A bouyancy control system that allows a fully controlled ascend and descend through the water column.  The cage can be suspended at any depth in the water column in any depth of water.

2.) Top portion of cage can be raised 14′ to allow net inspection and cleaning.

3.) Cage cube allows various net designs and configurations.

4.) Capable of larger rearing volumes at reduced cost/cubic meter.

5.) Full scale open water tested in 5 meter seas.

Open Water Systems Ltd. is currently seeking companies  or individuals that are interested in using this cage in real production conditions.  The cage can be seen at www.openwatersystems.com.  We can be contacted @ 705 377 4044 or by email @ jefftuerk@hotmail.com.  The full size cage can be dismantled and container shipped worldwide.


Aquaculture Co-ops – The way forward?

A number of weeks ago Andrew Duff spoke about co-operatives in Aquaculture. In particular, he suggested possible advantages for small producers achieving economies of scale in areas such as marketing to high value, large fish markets in Asia.

This concept interested me and I’ve been doing some research on some existing co-ops.

Broken Bay Oysters is one. They faced a tough problem a number of years ago and through grouping their funds were able to invest in the technology necessary to solve their predicament.

Here’s an example of a much larger scale co-op that represents a range of organic foods in Switzerland. Even though it’s not a purely aquaculture based co-op, it is funding important research into 1) processing of organic aquaculture products and 2) natural antioxidant constituents in fishmeal.

Here’s some information;

Getting back to purely aquaculture co-ops – Read this excerpt about the Texas Aquaculture Cooperative:

<<<<”The positive feasibility study provided the impetus for 31 producers to form the Texas Aquaculture Cooperative in the fall of 2002. Shimek is the co-op president and Hanson is vice president. They began processing their local catfish harvests in a building donated by Harold Bowers of Bowers Shrimp Company in Palacios.

Peter Woods became the Extension fisheries program specialist in the summer of 2002 and began working with co-op members to improve and expand their production ponds. He has helped growers produce 8,000 to 10,000 pounds of fish per acre. Most co-op members have several 8- to 10-acre ponds.

A few months later, with a business and marketing plan in hand, co-op members pooled $415,000 of their own start-up capital and built a 5,250-square-foot processing facility near Markham. The plant can process 150,000 pounds of fresh catfish per week.

The plant churned out more than 867,000 pounds of catfish in the last year, employed 24 full-time workers, and has pumped more than $17 million into the regional economy.”>>>>

Does anyone know of any WA or Australian Co-ops who are following a similar business growth strategy?

Essentials on Farm pond design and Building

Building farm ponds has become phenomena within aquaculture industry. They range from single purpose ponds to multipurpose ponds based on the needs for building the ponds. Some of the common uses for these ponds include fish farming, water reservoir purposes, irrigation purposes and recreation purposes.

The essentials in the design and construction of farm ponds are:

·         Adequate water source: The area where the pond is constructed should have bountiful supply of water either it be overland drainage, ground water, in stream flowing water or diverted water flow. The reliable source for supply of water in the pond is an essential determination at the design stage.

·         Proper Drainage Area: When designing the pond there are aspects to put into consideration like the measurements, runoff volume and evaporation rate. Selecting the proper area will facilitate fertilization of the pond and minimize the water loss from evaporation.

·         Determining the type of soil in the area is a precondition to building farm ponds. Areas with impermeable soils are the ones suitable for farm ponds since they minimize to the maximum or prevent the rate of water seeping downward which has an impact on maintaining the suitable water level.
