摘要： 民以食为天，鱼也不例外。目前海钓中，鱼饵的品种繁多，有荤饵有素饵（商品饵），有活体饵也有死体饵，有海洋生物饵，还有陆地生物饵等等。而鱼的口味也是五花八门，有的比较挑食，食性很窄；有的不那么讲究，食性很广；有的喜欢活饵，有的死活通吃，可谓“萝卜青菜各有所爱”。

摘要： Constructed wetlands represent economically and environmentally viable tools for the control of water pollution, for example through wastewater treatment. In this study, we assessed the growth, morphology, and chlorophyll contents of 3 southern Taiwan native mangrove species (Avicennia marina, Rhizophora stylosa, and Lumnitzera racemosa) planted in monoculture free water surface mesocosms, with respect to different hydraulic residence times (HRTs: 0.5, 1, and 2 d plus 1 drained treatment) and mariculture effluents over a 10-month period in 2007-2008. The seedlings of all 3 mangrove species survived under all mariculture wastewater treatments, but longer HRTs induced greater stress and suppressed mangrove growth. The net primary productivity and the final percent change in leaf number, leaf area, and leaf area ratio of the three mangrove species decreased with increasing HRT. The study concludes that the growth of A. marina was better than that of R. stylosa and L. racemosa under waterlogging conditions with mariculture effluent. Therefore, planting A. marina is suggested as a more appropriate design for seawater mangrove constructed wetland to treat aquaculture wastewater in southern Taiwan. © 2013 American Scientific Publishers All rights reserved.

摘要： Mariculture is one of the major seafood supplies worldwide and has caused serious environmental concerns on the coastal zone. Its rapid development has been shown to disrupt the sediment ecosystems and thus influence the benthic bacterial communities. Bacterial diversity and community structure within both adjacent farms and non-cultured zones intertidal sediments along the coasts of Qinhuangdao and Dalian, China, were investigated using full-length 16S rRNA gene-based T-RFLP analyses and clone library construction. Richness and Shannon-Wiener index were significantly increased at sites adjacent the mariculture farm with mean values of 29 and 2.97 from peak profiles of T-RFLP result. Clustering analyses suggested that impacts of mariculture on bacterial diversity of sediment were significantly larger than those resulted from temporal and spatial scales. Upon comparisons of RFLP patterns from 602 clones from libraries of the selected five samples, 137 OTUs were retrieved. Members of gamma- and delta-Proteobacteria, Bacilli, Flavobacteria, and Actinobacteria were recorded in all libraries. In addition, gamma-Proteobacteria were dominant in all samples (21.7 similar to 45.0 %). Redundancy analysis revealed that the distribution of bacterial composition seemed to be determined by the variables of salinity, PO4 (3-)-P, NH4 (+)-N, and Chlorophyll a content. The phyla of gamma-Proteobacteria, Clostridia, Flavobacteria, Bacilli, and Planctomycetes were principal components to contribute to the bacterial differences of clone libraries. Our finding demonstrated that these phyla could display variations of bacterial composition linked to environmental disturbance resulted from mariculture.

摘要： To elucidate the effects of scallop mariculture on the macrobenthic community in a moderate energy system, bimonthly samples from four transects along a distance gradient in Sishili Bay, the northern Yellow Sea of China, were investigated. Differences in macrobenthic community structure along the distance gradient were evaluated using univariate and multivariate analyses. The AZTI's Marine Biotic Index (AMBI) and multivariate-AMBI analyses indicated that the macrobenthic community suffered little disturbance from the scallop culture. Consistently, the results of two-way analysis of similarities demonstrated that macrobenthic communities showed no difference along the distance gradient, but were significantly affected by the sampling months and transects. This conclusion was also confirmed by other univariate and multivariate analyses. The concentration of total organic carbon was 17.27 +/- A 6.05 mg g(-1), which is below the dangerous threshold of 35 mg g(-1) toxic to benthic fauna. Combined results revealed that no detectable effects on the macrobenthic community were caused by intensive and long-term scallop culture in this moderate energy system. This is likely due to the influence of local hydrodynamics and it is recommended that intensive scallop farming be located in areas with strong tidal or current flows.
