Inshore Fisheries database

The database collects environmental and biological data on potential commercial species found in the inshore marine environment of the Falkland Islands (within the 3 nautical miles). The focal species are: giant barnacle (Austromegablanus psittacus), rough thorn drupe (Acanthina monodon), keyhole limpets (Fissurella spp.), striped clam (Eurhomalea exalbida), red sea urchin (Loxechinus albus), giant mussel (Choromytilus chorus) and the ribbed mussel (Aulacomya atra).

Lineage The database is a collection of data at sampling locations in the inshore marine environment of the Falkland Islands (within the 3 nautical miles). All locations are georeferenced through GPS and corresponf to where diving occurs. Samples of the potentially commercial species (see abstract) are collected by divers who also gather information on habitat types, benthos, substrate, exposure and other environmental factors. This information are collected using the standard JNCC marine habitat form. Species of interest are counted as well as a qualitative assessment of all other species (flora and fauna) is carried out. Sampling occurs along a 30 metres transect with quadrats placed randomly at every metre on each side of the transect on a staggered fashion (hence survey area is 60 sqm). Photos are taken of each quadrat and of the surrounding environment for context and later analyses. The divers collect specimens of the focal species present for lab analyses. The JNCC form is entered in the main database, which is Marine Recorder, while specimen are taken to the lab for the collection of biological data. Samples of gonads are fixed in 10% buffered formaline solution with glacial acetic acid and shells are cleaned and kept for ageing. Gonads go through a full histological process where ultimately slides of gonads are analysed to determine sex, maturity stage etc.
