Many recreational fisheries do not have mandatory reporting and rely on probability-based survey data to produce estimates of effort and catch to inform management decision making. Reliable data are required for estimates to be accepted by managers and stakeholders. Estimates were determined from off-site Phone-Diary (PD) and on-site Bus-route Access Point (BAP) with supplemented Remote Camera (RC) surveys over the same 12-month period to compare and corroborate effort and catch estimates for a boat-based recreational fishery in Western Australia. Similar distributions of raw catch data were found among surveys. Effort estimates were comparable for the PD and BAP complemented RC methods. Although catch estimates from the PD survey were generally lower than those from the BAP survey, catch estimates for most species were comparable for the PD and BAP complemented RC methods. The precisions associated with most of the catch and effort estimates from the different surveys were relatively similar and reliable (RSE < 40 %). However, measurement bias influenced catch and effort estimates from the BAP survey. The relatively low cost and availability of a licensing database as a sampling frame favour the PD survey as a long-term monitoring tool for this boat-based recreational fishery. While choice of survey design is subject to management requirements, financial and logistic constraints, this study demonstrates an approach to corroborate estimates for recreational fisheries.

在西澳大利亚州以船为基础的休闲渔业的综合调查设计中证实的努力和收获
许多休闲渔业没有强制性的报告,而是依靠基于概率的调查数据来估算工作量和捕捞量,从而为管理决策提供依据。需要可靠的数据,管理者和利益相关者才能接受估计值。估计值是通过在同一12个月内通过异地电话日记(PD)和现场公交路线访问点(BAP)以及补充的远程摄像机(RC)调查来确定的,以比较和证实工作量并捕获对西澳大利亚的船上休闲渔业。在调查之间发现原始渔获量数据的分布相似。PD和BAP补充RC方法的工作量估算值可比。尽管PD调查中的渔获量估算值通常低于BAP调查中的渔获量,对于PD和BAP补充的RC方法,大多数物种的捕捞估计值是可比的。与来自不同调查的大多数捕捞量和工作量估算值相关的精度相对相似且可靠(RSE <40%)。但是,测量偏差影响了BAP调查中的捕获量和工作量估计。许可数据库作为样本框架的成本相对较低且可用性较高,这有利于将PD调查作为该船用休闲渔业的长期监测工具。虽然调查设计的选择取决于管理要求,财务和物流限制,但本研究表明了一种确证休闲渔业估计的方法。与来自不同调查的大多数捕捞量和工作量估算值相关的精度相对相似且可靠(RSE <40%)。但是,测量偏差影响了BAP调查中的捕获量和工作量估计。许可数据库作为样本框架的成本相对较低且可用性较高,这有利于将PD调查作为该船用休闲渔业的长期监测工具。虽然调查设计的选择取决于管理要求,财务和物流限制,但本研究表明了一种确证休闲渔业估计的方法。与来自不同调查的大多数捕捞量和工作量估算值相关的精度相对相似且可靠(RSE <40%)。但是,测量偏差影响了BAP调查中的捕获量和工作量估计。许可数据库作为样本框架的成本相对较低且可用性较高,这有利于将PD调查作为该船用休闲渔业的长期监测工具。虽然调查设计的选择取决于管理要求,财务和物流限制,但本研究表明了一种确证休闲渔业估计的方法。许可数据库作为样本框架的成本相对较低且可用性较高,这有利于将PD调查作为该船用休闲渔业的长期监测工具。虽然调查设计的选择取决于管理要求,财务和物流限制,但本研究表明了一种确证休闲渔业估计的方法。许可数据库作为样本框架的成本相对较低且可用性较高,这有利于将PD调查作为该船用休闲渔业的长期监测工具。虽然调查设计的选择取决于管理要求,财务和物流限制,但本研究表明了一种确证休闲渔业估计的方法。
