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.
