To achieve sustainable use of living marine resources it will be necessary, in many cases, to reduce harvest rates from present levels. This will lead to a reduction of income in the short term. Community support for sustainable fishing interventions will be higher if alternative livelihood sources exist, or if assistance is given to develop such alternatives. An important strategy of WorldFish in the Pacific is therefore to link fishery management projects with activities that provide alternative sources of income. Partnerships are essential to accomplish this.
