The Welsh Government will offer the meat and fisheries sector over £3m to prepare for Brexit.
The money will come from the Welsh Government's £50million EU Transition Fund.
Over £2million will be used to help develop the red meat sector and support farmers to improve their businesses in preparation for trading following Brexit. Funding will also be used to encourage companies based in the EU to set up their operations in Wales.
Carwyn Jones said Brexit presents challenges to agriculture and fishing industries in Wales.
