【 摘 要 】

The present study reports the introducing of mangrove management through community-based silvofishery pond according to the density of sapling and seedling stage in Lubuk Kertang village, Langkat, North Sumatra, Indonesia. The vegetation in the silvofishery pond consisted of Rhizophora apiculata, R. mucronata, and Avicennia marina. Silvofishery pond was introduced with an area total of 8,484 m2, with an area of 0.4242 ha in each pond of dominated seedlings and saplings, respectively. In the predominated seedling density over sapling showing almost twice found that seedling density consisted of 297 individual/ha which domination of R. apiculata compared to sapling density of 144 individual/ha. Similarly, 726 individual/ha was recorded in the sapling stage, where R. mucronata dominated. Furthermore, the seedling density in the sapling domination ponds for the seedling level was 398 individual/ha. R. mucronata detected in ponds with sapling dominance and seedling domination generally located in the middle part of the pond. By contrast, R. apiculata dominated the seedling level either in the seedlings or saplings stage. Introducing silvofishery with seedling and sapling stages should use recommended species such R. mucronata and R. apiculata to sustain nutrient of fish and to generate high phytoplankton growth.
