  • comparing physical and biological impacts on seston renewal in a tidal bay with extensive Shellfish Culture
    Journal of Marine Systems, 2019
    Co-Authors: Long Jiang, Theo Gerkema, J.w.m. Wijsman, Karline Soetaert
    Abstract:

    Shellfish Cultures worldwide are often located in sheltered marine bays. The Oosterschelde is such a bay in the southwestern delta of the Netherlands, harboring extensive Shellfish Cultures, whose yield is partly driven by seston renewal from the North Sea. Tracer experiments performed with a three-dimensional hydrodynamic model were used to study the relative influences of benthic filtration and physical processes on seston replenishment. The model exhibited good skills in reproducing observed water level, temperature, salinity, and current velocity during 2009–2010. Turnover and residence times as indicators of water renewal showed substantial gradients from the mouth to head of the Oosterschelde. Surveyed bivalve biomass and empirical filtration rates were incorporated to estimate the effects of aquaCulture on the seston concentration. The filtration created strong bio-deposition suppressing the eastward seston transport and causing <10% of external seston to be delivered to the head of the Oosterschelde. The effect of biological filtration on seston transport was comparable to that of physical forcing. This simple approach combining effects of physics and benthic communities can be applied more generally in food sustainability assessments of tidal bays.

  • Study on assessment of the environmental quality and grading of Shellfish-Culture areas in Xiamen Bay
    Marine Fisheries Research, 2008
    Co-Authors: Cai Jian-ti
    Abstract:

    According to the data of environmental survey on harmful substances (such as Cu, Pb, Zn, Cd, Hg, As, petroleum, HCH,DDT, PCBs, coliforms, DSP, PSP) in seawater, surface sediments and Cultured organisms from Shellfish-Culture areas of Xiamen Bay in April and October 2005, eco-environmental quality of Shellfish-Culture areas was assessed and classified by seawater quality index method, surface sediment quality index method, Culture Shellfish quality index method and the Shellfish Culture eco-environmental quality synthesis assessment index method. The results showed that the quality grades of seawater, surface sediment and Cultured Shellfish ranged between Grade 2 and Grade 7,and averaged Grade 3, Grade 5 and Grade 4, respectively. The Shellfish-Culture eco-environmental quality ranged between Grade 2 and Grade 7, at a mean of Grade 4. Overall, the eco-environmental quality of Shellfish-Culture areas of Xiamen Bay was at a regular level; specifically, the seawaters were of relatively good quality, surface sediments were of relatively poor quality, and the Cultured Shellfish were of ordinary quality. The major contaminants were coliforms and petroleum. In the Shellfish-Culture areas of Xiamen, two areas belonged to the first class, occupying 8% of all areas; 18 areas belonged to the second class, occupying 72% of all areas. In addition, there were 9 areas belonged to 2a class, which were relatively clean and occupied 36% of all areas, six areas belonged to 2b class which were lightly polluted and occupied 24% of all areas, three areas belonged to 2c class which were medially polluted and occupied 12% of all areas. There were 5 seriously polluted areas belonging to the third class and occupying 20% of all areas. The results of environmental quality assessment and grading of Xiamen Shellfish habitat correlates well with the present situation of environmental pollution in Xiamen Shellfish-Culture areas.
