CaSP Cymru has replaced the previous Wales Marine Action and Advisory Group (WMAAG) which was formed in 2014 to provide overarching strategic advice in developing the Marine Transition Plan.
Mae PMacA Cymru wedi disodli hen Grŵp Cynghori a Gweithredu Cymru ar Faterion Morol, a ffurfiwyd yn 2014 i gynnig cyngor strategol cyffredinol wrth i'r Cynllun Pontio Morol gael ei ddatblygu.
