Brief description
The Peel-Harvey Estuary was divided into five regions; the Entrance Channel, Eastern Peel Inlet, Western Peel Inlet, Northern Harvey Estuary and Southern Harvey Estuary. Within each region four sites were sampled seasonally over two years (total of 8 sampling occasions). At each site, sampling of fish was conducted using seine nets with length and weight of all collected fish measured. In addition, water temperature, salinity, dissolved oxygen were measured at each site. The aim of the study is to develop cost-effective strategies for monitoring the fish community. Data is still being collected / processed and will be released at the end of WAMSI program.Lineage
Statement: Within each region there were four sites that were sampled seasonally over two years (total of 8 sampling occasions). The fish fauna of the Peel-Harvey Estuary was sampled using a 102.5 and 21.5m seine net. The 21.5m seine net was carried out into the water by two researchers. At a depth of approximately 1.5m the net was strung out parallel to the shoreline. The researchers at either end of the net then walked in towards each other forming a circle shape with the net which was then dragged up onto the beach and emptied. The 102.5m net was deployed from a small boat. One of the researchers remained on the beach holding one end of the net whilst the other drived the boat in a semi-circle fashion, starting near the shore and finishing back near the shore. The net was then dragged up onto the beach and emptied. The nets used to sample both estuaries are identical to those used in previous studies and thus allow for direct comparisons to be made between sampling periods. These methods are the most appropriate to obtain sound quantitative data on fish communities in this type of habitat and have been used extensively in other estuarine research in south-western Australia. At each sampling site on each sampling occasion the water temperature, salinity and dissolved oxygen content was recorded using a YSI 556 MPS temperature, salinity and conductivity meter. In the laboratory each sample was sorted and each individual fish was identified to species level. Each individual of each species was measured to the nearest 1mm and, in the case where there are more than 50 fish for a species in a single sample only 50 fish were measured. The total weight of each species in each sample was recorded to the nearest 0.01 g.Created: 04 11 2008
