Abstract

Mororejo village is a village located in a coastal area located in Kaliwungu District, Kendal Regency. Mororejo village has a population of around 4,258 people with 60% of the population working as fish farmers who use and utilize land near the sea by establishing ponds that are their daily livelihood. Silvofishery is a traditional technology aquaculture model that combines fishery business with mangrove planting, which can increase pond productivity. The purpose of this paper is to find out the silvofishery model that has been applied by coastal communities in Kendal Regency. The application of silvofishery system in Mororejo village is traditional ditch pond, with a range of 80% : 20 % mangrove. n. Types of mangrove plants planted are Rhizophora sp and Avicennia sp. Mangroves can function as shrimp aquaculture waste filters (nitrate reduction 44,5 % , ammonia 46,6% and nitrite 59,0%) and increase the productivity of shrimp culture (average growth weight 49,833 gr). Socialization and research activities about the benefits of silvofishery for communities in the Kendal regency coast have not been done much but all stakeholders already have a good perception and agreed to apply silvofishery as an alternative system for sustainable aquaculture.
