Alternative approaches to assessment (including the use of local knowledge) Patrick McConney, CERMES, UWI Cave Hill Campus
Purpose of this presentation • By the end of this presentation participants will • Be able to ask other presenters questions that both challenge and clarify how useful stock assessment is • Appreciate that stock assessment may not be feasible or necessary in all situations (and to identify these) • Understand a bit about differences between fishery assessment and stock assessment that are important • Have a better idea of how some simple techniques can be alternatives to, or supplement, stock assessment • Appreciate the contribution that local knowledge can make to stock assessment or less formal alternatives • Have new contexts in which to put stock assessment
So what does this fisherman think about selectivity, catch coefficients, fishing effort and responsible fishing?
Some questions to consider (among many) • Since stock assessment is a means to an end, or a tool, do you know what the end or goal or aim is? • If stock assessment is part of a larger fisheries management/governance process how does it fit? • If there is opportunity cost to stock assessment, then what opportunities are foregone for you? • Are there situations in which stock assessment is not at all useful/applicable/feasible/justifiable? • What is the capacity to sustain or adapt various types/methods/approaches to stock assessment?
Can you do stock assessment in a bucket or while at lunch? Share your expert opinion! Cultural preference for whole fish? Catering preference for plate fish?
Fisheries philosophy 101 • You cannot manage fish, so you must manage people • Are you really prepared to manage people? • Assessment, by definition, is based upon human values; nothing is “given”, not even what we label as objective • This kicks in before science offers advice
Stock assessment is part of fishery assessment Packaging, processing Quality assurance Transport options Marketing & distribution Fishing methods funds The fish chain “fish” Stock assessment Consumer preferences International agreements Scientific research Management aims/measures
The best use to which this fish can be put…tourism use, food security, export, poverty alleviation depends on so many things…stock assessment is just a part
Determining which fisheries are “worth” stock assessment can be a very prickly issue indeed
Effectively exchanging information between different knowledge systems is challenging
Combine local knowledge with science information • Climatic conditions • Life histories, cycles • Species harvested • Fishing vessels used • Fishing methods used • Processing of catch • Trade and income • Fish consumption • Alternative livelihoods • Culture and religion
