“…Considering the complexity of a fishery system, simulation models can be built incorporating both fish population dynamics and fishing effort dynamics. Yew and Heaps (1996), for example, developed a model incorporating bio‐socioeconomic effects of alternative management policies for a small pelagic fishery in north‐west peninsular Malaysia. They showed that the existing policy of limited entry licensing would not achieve the expected outcome as fishers could increase effort by fishing more days or by ‘capital stuffing’ their vessels.…”

The behavioural dynamics of fishers: management implications

In pursuing their livelihood, fishers develop strategies when faced with changes in regulations and other fishery conditions. Changes involve each individual in a decision‐making process governed by his/her own goals or constraints. Despite this reality, the complex dynamics of fishing has usually been ignored in designing management initiatives, which has contributed to management failures in many parts of the world. Fishers have generally been treated as fixed elements, with no consideration of individual attitudes based on their operating scales (geographical, ecological, social and economic) and personal goals. We review existing research on the social, economic and behavioural dynamics of fishing to provide insight into fisher behaviour and its implications for fisheries management. Emphasis is placed on fisher perception, and how fishers develop dynamic fishing tactics and strategies as an adaptive response to changes in resource abundance, environmental conditions and market or regulatory constraints. We conclude that knowledge of these dynamics is essential for effective management, and we discuss how such information can be collected, analysed and integrated into fisheries assessment and management. Particular emphasis is placed on small‐scale fisheries, but some examples from industrial fleets are provided to highlight similar issues in different types of fisheries.

“…This is in part due to relative ease of data collection; catch data can be collected at ports or landing sites. While catch data provides important information on the number of individuals harvested, it does not provide information on the expended effort, including details on gear, capital and labour used to harvest stocks (Yew and Heaps 1996). The amount and types of resources devoted to fishing is directly related to the harvesting capacity of the fleet (Kirkley et al.…”

Quantifying fishing effort: a synthesis of current methods and their applications

The need to accurately quantify fishing effort has increased in recent years as fisheries have expanded around the world and many fish stocks and non‐target species are threatened with collapse. Quantification methods vary greatly among fisheries, and to date there has not been a comprehensive review of these methods. Here we review existing approaches to quantify fishing effort in small‐scale, recreational, industrial, and illegal, unreported and unregulated (IUU) fisheries. We present the strengths and limitations of existing methods, identifying the most robust methods and the critical knowledge gaps that must be addressed to improve our ability to quantify and map fishing effort. Although identifying the ‘best’ method ultimately depends on the intended application of the data, in general, quantification methods that are based on information on gear use and spatial distribution offer the best approaches to representing fishing effort on a broad scale. Integrating fisher’s knowledge and involving fishers in data collection and management decisions may be the most effective way to improve data quality and accessibility.

The Korean Government is in the process of establishing a plan for managing fishing effort by setting up the maximum fishing gear usage per fishery type for the recovery of fishery resources. This will aid settlement of disputes between fishery sectors over fishing gears, and the stability of fishing business conditions. Especially in the setting up of the maximum fishing gear usage, economic standards as well as biological standards are being considered as significant factors to promote the sustainable and economically viable development of fisheries. This study is, thus, to analyze the optimal economic fishing gear usage (EMEY) as the most economically efficient usage for the common octopus trap fishery, one of the most controversial sectors in establishing maximum fishing gear usage. Data from logbooks per trip were used for estimation of EMEY per trip because it was considered there were limitations of data available for analyses. As a finding drawn from the analyses, the EMEY of common octopus trap vessels per trip has to be decreased by approximately 13%. That is, reducing the trip trap usage up to the level of EMEY can lead to the reduction of trip fishing costs, thereby resulting in increased trip profits.KEY WORDS: common octopus, fisheries management, maximum economic yield, maximum sustainable yield, open access, optimal economic fishing effort, trap fishery.
