A 12-month survey of recreational fishing in the Swan- Canning Estuary Basin of Western Australia during 1998-99

چکیده
A survey of recreational boat-based and shore-based fishing in the Swan-Canning Estuary Basin was conducted between August 1998 and July 1999. During the survey 1,302 interviews were conducted at boat ramps. The majority of these (62%) were not involved in fishing or crabbing activities, with a further 18 per cent fishing in the adjacent ocean. Of the remainder, 139 boats had been crabbing and 154 angling (29 were both crabbing and angling) within the Swan-Canning Estuary Basin. In addition to the interviews at boat ramps, 378 shore-based fishing parties were interviewed. The survey estimated the total annual boat-based recreational fishing effort as 22,265 fisher days, with 44 per cent of this effort targeting blue swimmer crabs. The total annual shore-based recreational fishing effort was estimated to be 8,073 fisher days, with only 9 per cent of this effort targeting blue swimmer crabs. The estimated total recreational catch of blue swimmer crabs from the Swan-Canning Estuary Basin was 20,875 crabs or 7.3 tonnes. This consisted of a boat-based catch of 20,176 crabs and a shore-based catch of 699 crabs. Most crabs (94%) kept by recreational fishers were male. The most common fish species kept by anglers in the Swan-Canning Estuary Basin are (in order of number kept) common blowfish, tailor, whiting other than King George, Australian herring, black bream, flathead, trumpeter and flounder. There was a very high level of compliance with fishing regulations amongst all anglers and boat-based crabbers. However, 5.4 per cent of shore-based crabbing parties interviewed were found to have kept undersize crabs. Less than one per cent of boats with two or more people on board achieved the daily boat limit of 48 crabs. However, a larger proportion (7.1%) of boats with only one person on board achieved their daily bag limit of 24 crabs. No anglers caught their daily bag limit of any fish species. Fish. Res. Rep.

Protecting recreational water quality where 'whole-of-body contact' activities occur is important from a public health and economic perspective. Numerous studies have demonstrated that infectious illnesses occur when swimming in faecally polluted waters.

Seagrass distribution and other measures of seagrass condition have been used as broad scale biological indicators of marine and estuarine health. To date the distribution of seagrass in the Swan-Canning Estuary has been assessed based on aerial photographs, which is ineffective in deep, turbid waters. Sidescan sonar systems (SSS) provide acceptable results in a much wider range of environmenta...

As with all coral reef systems, the ecology of Ningaloo Reef is closely linked to water circulation which transport and disperse key material such as nutrients and larvae. Circulation on coral reefs may be driven by a number of forcing mechanisms including waves, tides, wind, and buoyancy effects. Surface waves interacting with reefs have long been known to dominate the currents on many coral r...

The whole of the Swan-Canning Estuary, in the south-west of Australia, is impacted by human activity, and the selection of a local reference site to assess the impact of environmental contamination on the health of biota is not possible. To determine whether fish depurated under laboratory conditions could be used as an alternative to a reference site; adult black bream (Acanthopagrus butcheri)...

The procedures involved in model development may be set out as a ten-step process, beginning with defining the purpose of the model and ending with evaluation of the appropriateness and utility of the completed model. This process, recently outlined by Jakeman et al. [2006], is often iterative as model development is a continuous process that refines and improves the intended capacity of the mo...
