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 areRhizophora 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.
Highlights
Coastal area is one of the important economic activities at present
The selection of the right silvofishery pond model is highly dependent and will be influenced by the status of the mangrove ecosystem, so there is no one model that can be said to be most appropriate in all situations [16]
Based on the consideration of the management of mangrove ecosystems and cultivation technology applied in the area mentioned above, it can be stated that through the biotechnical conditions of each of the approach models, the most likely is the traditional trench pond model
Summary
Coastal area is one of the important economic activities at present. Ponds are one type of habitat that is used as a place for brackish water aquaculture activities located in coastal areas [3]. The aquaculture area in Mororejo village has an average production potential of up to 500 kg per ha in a single harvest [2]. With the presence of mangroves in the area of the pond is expected to help increase pond production and make farmer income increased. The right management strategy can help increase pond production so that farmer income will increase
