Abstract
<p>Mangrove seedling growth in silvofishery pond is limited to water quality dynamics while the water quality dynamically changes. This research aimed to study the changes of environmental factor condition in silvofishery pond and to analyze its impacts on the growth of mangrove seedling. Research experiment involved18 treatment plots with mangrove Rhizophora mucronata seedling. Observed parameters included temperature, turbidity, salinity, pH, DO, TSS, BO, N and P. Calculation was conducted for the deviation of each parameters. Mangrove growth parameters were including height and diameter growth while its data processing was absolute daily growth. Data analysis was conducted through regression. The result showed there were changes on environment parameters. Growth rate of R. mucronata showed variations on absolute daily height growth rate range of 0.215-3.333 mm/day (average 1.296 ±0.036 mm/day), while absolute daily diameter growth rate range was 2.15x10-3-0.196 mm/day (average 4.25x10-2 ± 3.59x10-2 mm/day). The analysis of regression showed several parameters effectedthe growth of mangrove seedlings including temperature, temperature change, turbidty, salinity change, pH, pH change, and DO on the growth of R. mucronata seedlings. This research concluded that environment parameters and its changes had significant effects on the growth of mangrove seedling. </p><p><strong>How to Cite</strong></p><p>Hastuti, E., &amp; Budihastuti, R.

Highlights
Degradation of mangrove ecosystem is caused b y t h e e x t e n s i v i c a t i o n o f p o n d
Silvicultural ponds occupied in this research have embankment-canal systems in which mangrove seedlings were planted in the inlet and outlet canals of the ponds which are functioned as biofilters
Some parameters tended to decrease among observations indicated by negative value change, including temperature, turbidity, pH, dissolved oxygen (DO), OM, N, P and total suspended solids (TSS)
Summary
Degradation of mangrove ecosystem is caused b y t h e e x t e n s i v i c a t i o n o f p o n d. R e f o r e s t r a tion efforts had been conducted to recover mangrove ecosystem and its advantages (Kusaeri et al, 2015). Economic development through mangrove reforestration is expected to be achieved through its enviromental services and tourism. Development of mangrove as an ecotourism spot had been studied in several research. Proper management should be formulated to avoid conflict of interest on mangrove utilization (Fahrian et al, 2015). According to Kartijono et al (2010), mangrove ecosystem is an important habitat for various animal species which are potential for tourism
