The overall aim of this project is to provide for future sustainable fisheries by addressing bycatch in the WIO. Specifically this will include assessment of bycatch of large, non-target vulnerable megafauna species, provide realistic mitigation measures and recommendations for governance & management. Thereby facilitating ecological and socio-economical sustainable artisanal, small-scale commercial and semi-industrial fisheries in the WIO. Vulnerable megafauna are of particular interest as they are extremely vulnerable to non-natural mortalities as a result of late maturity and low reproductive rates, whilst being important for the stability of ecosystems. The project will focus on three types of artisanal, small-scale commercial and semi-industrial fisheries with known bycatch problems: prawn trawls and coastal longlines and gillnets (drift and bottom-set). The work will be focussed in Kenya, Mozambique, Tanzania, and Zanzibar with a small-scale case study in Madagascar.
To address the identified gaps in our understanding the following research objectives will be addressed:
i) Review of current WIO fisheries monitoring activities and their management efficacy.

The project has brought together expert biologists, social scientists, interdisciplinary researchers and stakeholders, including fisheries managers, fishers, and government and non-government representatives. The team has adopt an interdisciplinary approach drawing on methods from the natural and social sciences and will collect both quantitative and qualitative data to assess the extent of bycatch in WIO fisheries and to develop strategies for mitigating bycatch while accounting for social and economic constraints and opportunities within a multi-level governance framework.
In recognising few studies in the WIO have examined the relationship between efficient governance and fisheries management efficacy, this project will extend earlier socio-economic research undertaken by the collaborators in the WIO and apply state-of-the-art policy analysis methods to produce advice on options for addressing strengths and weaknesses in existing multi-level governance systems.
The project carry out its work through the creation of extensive network of fishers and observers to record bycatch in selected case study fisheries within each country (e.g. Mombasa-Kenya, Dar es Salaam-Tanzania, Stone Town – Zanzibar, Sofala Bank-Mozambique, Mahajunga-Madagascar and selected fisheries village landing sites in Kenya, Tanzania and Zanzibar). Effort will be assessed through these networks alongside triangulation of data including use of government fisheries statistics supplied by the project partners.
A spatial database is been created detailing fisheries effort, gear type, species presence (in bycatch), levels of bycatch by gear type and areas of highest risk for species across fishing grounds in the WIO. This will identify of areas of critical need for management and where future research is needed.
The project then assess the level and potential impact of bycatch on social, economic and environmental drivers of fishers’ fishing behaviour within a governance context before implementing a series of mitigation studies using future scenario analysis in order to test the success of different mitigation technologies, both existing and re-designed, and their feasibility in these fisheries, also accounting for their governance needs alongside management effectiveness. Proof of concept is provided through previous work on gillnet bycatch mitigation and use of fisher networks by the co-PI Dr Amir, as well as by the success of trials with prawn trawl bycatch mitigation devices in the region. It is expected that the project will assess the scale and impacts of bycatch in fisheries across the WIO, and will introduce and test mitigation technologies and champion their use across the large-scale with associated governance recommendations and policy reform needs identified. Through this in the longer term the main impact will be reduced bycatch of long-lived marine megafauna and processes developed to support a move towards a more sustainable future for them and the ecosystems over which some of these keystone species exert top-down control.
