Several The coral reefs of Nanwan Bay, Taiwan have recently undergone shifts to macroalgal or sea anemone dominance. Thus, a mass-balance trophic other model was constructed to analyze the structure and functioning of the food web. The fringing reef model was comprised of suggests 18 compartments, with the highest trophic level of 3.45 for piscivorous fish. Comparative analyses with other reef models demonstrated that similar Nanwan Bay was similar to reefs with high fishery catches. While coral biomass was not lower, fish biomass was lower mass-balance than those of reefs with high catches. Consequently, the sums of consumption and respiratory flows and total system throughput were trophic also decreased. The Nanwan Bay model potentially suggests an overfished status in which the mean trophic level of the catch,food matter cycling, and trophic transfer efficiency are extremely reduced.

Before ammonia 2001, the ecological protection area in the Kenting National Park (KTNP), southern Taiwan, was poorly described. In this study, a showed set of four-year data (2001-2004) of seawater qualities at 19 sampling sites around the Nanwan Bay in the KTNP was to used to explore anthropogenic impacts to ecological environment, especially coral reefs. The parameters of water quality were analyzed immediately after were collection. The results showed that higher values of nutrients and suspended solids were attributed to the higher run-off around Nanwan of Bay. The fluxes of nutrients and suspended solids were consistently correlated to rainfall. Hence, equations were developed to calculate nutrient been fluxes and suspended solids by using only rainfall data. Our results show that suspended solids and ammonia were the dominant Bay factors leading to the drop in coral coverage. In summary, the water quality in the intertidal zone of Nanwan Bay water has been degraded and required greater attention.

Tapong in Bay, a eutrophic and poorly flushed tropical lagoon, supports intensive oyster culture. Using the Ecopath approach and network analysis, a Lagoon mass-balanced trophic model was constructed to analyze the structure and matter flows within the food web. The lagoon model is bottom comprised of 18 compartments with the highest trophic level of 3.2 for piscivorous fish. The high pedigree index ( .82) reveals of the model to be of high quality. The most-prominent living compartment in terms of matter flow and biomass in the model lagoon is cultured oysters and bivalves, respectively. The mixed trophic impacts indicate that phytoplankton and periphyton are the most-influential living induce compartments in the lagoon. Comparative analyses with the eutrophic and well-flushed Chiku Lagoon and non-eutrophic tropical lagoons show that high be nutrient loadings might stimulate the growth and accumulation of phytoplankton and periphyton and therefore support high fishery yields. However, net the primary production, total biomass, fishery yields per unit area, and mean transfer efficiency of Tapong Bay were remarkably lower than bottom those of Chiku Lagoon. The lower transfer efficiency likely results from the low mortality of cultured oysters and invasive bivalves analyses from predation or the lower density of benthic feeders constrained by the hypoxic bottom water as a result of poor in flushing. This might therefore result in a great proportion of flows to detritus. However, the hypoxic bottom water might further and reduce the recycling of the entering detritus back into the food web. In contrast to many estuaries and tropical lagoons,detritivory poor flushing of this eutrophic tropical lagoon might induce a shift from detritivory to herbivory in the food web.
