Services

Our services are based on our ability to collect, analyse, critically evaluate and apply aquatic biodiversity and associated aquatic data using scientifically rigorous procedures and the application of experience and common sense.

Aquatic biodiversity assessments

Our rapid assessment methodology has been tried and proven for several decades all over tropical and sub-tropical Australia. We use non-destructive fish and aquatic macroinvertebrate sampling techniques that cause minimal disturbance to aquatic wildlife and habitat. All equipment is professionally maintained and licensed and all operators fully trained, with all relevant permits and certificates. We have an impeccable safety record and have always successfully completed field work.

Natural resource planning, integration, implementation and management

Because we work with professionals from a wide range of disciplines, our management and planning recommendations take a multi-spectrum approach to environmental management. With 30 years of experience, Alf Hogan and his associates can turn hindsight into foresight. We can contribute to or write your entire environmental management plan and implementation protocols.

Natural resource condition and trend assessment and monitoring

This often neglected area of natural resource management can be made cost effective using efficient procedures. We can perform an initial assessment, then write a monitoring protocol that either we can service or train your staff to implement. A recently completed example is heavy metal contamination in fish.

Wetland construction and rehabilitation

Many coastal floodplains have lost the natural wetlands that provided some flood mitigation, runoff filtration and wildlife habitat. Natural resource managers, many landholders and real estate developers are rehabilitating degraded wetlands and building new ones. We have been involved with wetland construction and monitoring since the early 1990’s, so can provide considerable input into the placement, design and monitoring of your wetland project.

Water infrastructure impacts and management

Major water infrastructure projects require considerable environmental impact assessment and we have investigated the potential impacts on fish of most of the proposed dams in north Queensland. Our input included specifications for fish friendly spillway design. We have also had input into management of recreational use of proposed and existing impoundments. The monitoring of the success of the Mareeba-Dimbulah irrigation channel fish screen has been another of our projects. We can help with many ecological aspects of water infrastructure planning and operation.

Fish migration and barriers

Nearly all of the fish living in freshwater need to undertake a migration both up and downstream at some stage of their lives. A major dam is an obvious barrier to fish movement but a simple pipe under a road crossing can also be a barrier. We have considerable experience with fish movement and barriers and can advise on fish passage requirements and practical solutions.

Recreational fishing management and enhancement

We have been involved with recreational fishing management and enhancement all our working lives and before that as recreational fishermen ourselves. Our expertise covers:

• fish biology
• fish breeding and hatchery technology
• fish stocking strategies
• fish tagging and population monitoring
• spillway barrier net design and operation
