摘要:A 12-month creel survey of recreational boat-based and shore-based fishing in the Pilbara region
(Onslow to Broome inclusive) of Western Australia was conducted between December 1999 and
November 2000. During the survey 3,085 boat crews were interviewed at public boat ramps
when they returned from their fishing trips. Patrols conducted along the coastline interviewed
73 groups of boat-based fishers and 569 groups of shore-based fishers at fishing locations and
camp sites.
The total annual recreational fishing effort for the Pilbara region was estimated to be 201,000
fisher days (95%CI: 193,000 – 210,000). This comprised 109,000 fisher days by boats launched
from public ramps, 26,000 fisher days by boats launched from beaches and 67,000 days by
shore-based fishers.
The total recreational catch of all finfish species for the region was estimated at 383 tonnes
(95%CI: 331 – 435). This was approximately one sixth of the commercial catch of 2,442 tonnes
taken in the region during 2000. The most common species kept by recreational fishers in the
Pilbara region were (in order of estimated weight kept) spangled emperor (31 tonnes), narrowbarred
Spanish mackerel (28 tonnes), golden trevally (26 tonnes), blue-lined emperor (23 tonnes),
blue swimmer crabs (22 tonnes), blackspot tuskfish (22 tonnes), threadfin salmon (18 tonnes),
green mud crabs (17 tonnes), mullet species (13 tonnes), estuary cod (13 tonnes), black-tip
reef shark (12 tonnes), Queensland and Australian spotted mackerel (11 tonnes) and stripey
seaperch (11 tonnes). These catches do not include charter boats and therefore understate the
total recreational catch for the region.
Anglers have adopted modern technology to increase the efficiency of recreational fishing with
71 percent of boats launched from public boat ramps fitted with an echo-sounder and 40
percent using a global positioning system. There was a very high level of compliance with the
fishing regulations. Only five percent of boats launched from public ramps, three percent of boats
launched from the beaches and one percent of shore-based fishers interviewed kept undersize
fish. Very few fishers exceeded the bag limits. Most fishers had a reasonable knowledge of
the fishing regulations and knew the bag (67%) and size (67%) limits for the species they were
targeting or the predominant species they had caught.
