Our Projects and Case Studies

Supporting Hampshire Council, Carcinus Ltd provided electrofishing surveys for salmonid presence absence within a tributary of the R. Hamble.

Carcinus awarded a new contract by the Food Standards Agency (FSA) to undertake Sanitary Surveys and reviews of shellfish production areas.

Carcinus supports saltmarsh restoration project in the River Hamble using drone based mapping and photogrammetric processing and analysis.

Carcinus Ltd, partnered with MarineSpace Ltd and Alauda Aerial Surveys Ltd have written the JNCC’s latest Marine Monitoring Platform Guidelines on the use of unmanned aerial vehicles (UAVs) / drones, published June 2019.

Carcinus was commissioned to design and implement a multidisciplinary marine ecological survey of the approach channel and turning basin of Victoria Harbour, Hartlepool. The purpose of the study was to inform an Environmental Impact Assessment (EIA), with respect to predicted impacts of the proposed dredging and construction operations associated with scheme.

Carcinus Limited was commissioned to provide specialist marine ecology survey and reporting services in support of a new vessel lay-by berth within the entrance to the River Medina, East Cowes for the purposes of informing a marine licence application for dredge spoil disposal and an ecological impact assessment. The potential environmental effects originating from the proposed development were identified and screened. The need for a comprehensive sediment sampling programme was identified and delivered, to fully characterise the subtidal benthic ecology and sediment chemistry within and surrounding the proposed development.

Carcinus Ltd was commissioned by Hampshire County Council (HCC) to deliver river habitat surveys and impact assessment consultancy services with a focus on fish ecology in support of a proposed flood alleviation project in Winchester on the River Itchen. The project was in its initial phases and a baseline characterisation of the existing fisheries and fish habitats and initial environmental assessment to inform engineering considerations was required.

Carcinus Ltd was commissioned by Natural England and the Environment Agency to undertake a catchment wide lamprey population study on the River Itchen, Hampshire. The River Itchen is a designated Special Area of Conservation (SAC) and a Site of Special Scientific Interest (SSSI). The river forms part of Natural England’s “Hampshire chalk catchment” focus area and covers approximately 310 hectares of classic chalk river.

Carcinus Ltd was commissioned by Hampshire County Council (HCC) to deliver fish habitat assessment surveys and habitat enhancement consultancy services in support of the high-profile Botley Bypass highways project. The project has been permitted after passing through the Environmental Impact Assessment (EIA) process and planning phase. The scheme will involve the crossing of two watercourses, the first being the River Hamble by a new free-span bridge and the second located at Woodhouse Gully / Pudbrook Lake, where an existing culvert will be replaced.

Carcinus alongside MSDS Marine recently undertook a two-day public participation intertidal survey on the Sandwich Flats, Kent. The survey focused on four wreck sites and their surrounding environments within the bay. The study aimed to investigate the relationship between the social and economic value of the wrecks and their archaeological heritage and ecological importance.
