Abstract

Low or no disturbance sampling can be accomplished such as through a single-platform aquatic species and habitat sampling system with data integration and rapid processing capabilities that can address the need for sampling at variable depths over varied habitats, along with the simultaneous collection of linked physical and biological data. The platform may be based on a 24-36 foot boat, and may include a net mouth opener brace for an adjustable concentrator net and smaller drift net which may be attached to an adjustable sample chamber, perhaps containing variable mesh capture nets as well as cameras, water sampling equipment, and water quality sensors integrated with a fish finder, GPS, and other monitoring and data recording equipment. The depth of the net mouth opener brace and sample chamber may be adjustable using a depth control.

Claims

1. A method of sampling aquatic environments comprising the steps of:

mounting a net mouth opener brace to a boat;

attaching a front end of a concentrator net to said net mouth opener brace;

affixing a back end of said concentrator net to an organismically unrestrictive sample chamber;

passing aquatic samples through said concentrator net and said sample chamber via substantially uninterrupted flow; and

sensing at least one parameter of said aquatic samples.

2. A method of sampling aquatic environments as in claim 1, further comprising the step of installing at least one capture net inside said sample chamber.

3. A method of sampling aquatic environments as in claim 2, wherein said step of installing at least one capture net inside said sample chamber comprises the step of installing at least one capture net substantially at the fore of said sample chamber.

4. A method of sampling aquatic environments as in claim 2, wherein said step of installing at least one capture net inside said sample chamber comprises the step of installing at least one capture net substantially at the aft of said sample chamber.

5. A method of sampling aquatic environments as in any of claims 3 and 4, further comprising the step of immediately retrieving organisms from at least one capture net.
