“…As intensification of aquaculture is driven by the increasing demand for food fish, there have been increasing critiques of Chinese aquaculture practices because of the perceived negative environmental impacts (Xie and Yu, 2007;Cai et al, 2012aCai et al, , 2012bHerbeck et al, 2013;Zeng et al, 2013). It is alleged that a large amount of waste from aquaculture is released into environments that causes deterioration of aquatic ecosystems or wetlands (Amirkolaie, 2008;Verdegem, 2013), and at times being health hazards (Qin et al, 2007;Cai et al, 2012a).…”

“…A recent study showed that mean PO 3− 4 -P release from Meiliang Bay sediments was below 3.0 mg·m −2 ·d −1 (Fan and Wang, 2007). The external loading of total P to Lake Taihu was ∼10.0 mg·m −2 ·d −1 (Qin et al, 2007), which is the same order of magnitude as PO 3− 4 -P flux from zooplankton excretion ( Table IV). Considering that P released by zooplankton in this study was in a form available to phytoplankton, zooplankton may supply a significant source of P contributing to high phytoplankton biomass in Lake Taihu.…”

“…However, small zooplankton exhibit high P release rates and may thus play a significant role in nutrient cycling in tropical and subtropical lakes (Pinto-Coelho and Greco, 1999). Lake Taihu is a subtropical freshwater lake in China's Yangtze delta, with a surface area of 2338 km 2 and mean depth of 1.89 m. Situated in one of the most rapidly industrializing and populous regions of the world, Lake Taihu has suffered greatly from anthropogenic eutrophication since the 1980s (Qin et al, 2007). Although the lake is well-mixed and usually turbid due to sediment resuspension and high phytoplankton biomass, a clear water phase may be observed in spring and early summer due to low phytoplankton abundance.…”

Key-words:Lake Taihu, subtropical lake, metazoan zooplankton, phosphorus releaseThe contribution of metazoan zooplankton to internal phosphorus (P) cycling was investigated in Meiliang and Wuli Bays of Lake Taihu, a eutrophic, shallow lake in China by determining biomass and biomass specific P release rates. The zooplankton community of eutrophic Meiliang Bay was dominated by cladocerans, particularly Daphnia spp. and copepods, while dominant groups in hypereutrophic Wuli Bay included rotifers, copepods, and cladocerans. Release rates of PO 3− 4 -P ranged from 0.20 to 0.57 mg·g (dry weight) −1 ·h −1 in Meiliang Bay and 0.20 to 0.76 mg·g −1 ·h −1 in Wuli Bay. In most cases, P release rates were higher in Wuli Bay than Meiliang Bay. Phosphorus fluxes from zooplankton excretion varied from 5.34 to 57.41 mg·m −2 ·d −1 in Meiliang Bay and 8.20 to 70.02 mg·m −2 ·d −1 in Wuli Bay. Since P released by zooplankton in this study was in a form available to phytoplankton, zooplankton may represent a significant source of P contributing to high phytoplankton biomass in Lake Taihu. RÉSUMÉRejet de phosphore par le zooplancton métazoaire dans deux baies d'état trophique différent du lac Taihu (Chine) Mots-clés :lac Taihu, lac subtropical, zooplancton métazoaire, rejet de phosphore La contribution du zooplancton métazoaire à la circulation du phosphore interne (P) a été étudiée dans les baies Meiliang et Wuli du lac Taihu, un lac eutrophe, peu profond en Chine, par la détermination de la biomasse et les taux de libéra-tion de P par biomasse spécifique. La communauté du zooplancton de la baie eutrophe Meiliang a été dominée par les cladocères Daphnia spp, en particulier, et des copépodes, tandis que les groupes dominants dans la baie hypereutrophe Wuli comprenaient des rotifères, des copépodes, et des cladocères. Les taux de libération de PO 3− 4 -P variaient de 0,20 à 0,57 mg·g (poids sec) −1 ·h −1 dans la baie Meiliang et de 0,20 à 0,76 mg·g −1 ·h −1 dans la baie Wuli. Dans la plupart des cas, les taux de rejet en P étaient plus élevés dans la baie de Wuli que dans la baie Meiliang. Les flux de phosphore provenant de l'excrétion du zooplancton varient de 5,34 à 57,41 mg·m −2 ·d −1 dans la baie Meiliang et de 8,20 à 70,02 mg·m −2 ·d −1 dans la baie Wuli. Comme le P libéré par le zooplancton dans cette étude était dans une forme disponible pour le phytoplancton, le zooplancton peut représenter une source importante de P contribuant à la biomasse phytoplanctonique élevée dans le lac Taihu.

“…Do they present similar changes to Meiliang Bay? In this study, by comparing present macrozoobenthic assemblages to assemblages documented in past studies, we examine possible long-term changes in the macrozoobenthic assemblages in Lake Taihu between the two periods (1987À1988 and 2007), during which major changes took place in trophic state (Qin et al 2007). We predicted that the great changes in environmental conditions would affect the composition and structure of the macrozoobenthic assemblages.…”

Lake Taihu is subject to severe eutrophication due to high nutrient inputs. We compared the macrozoobenthic assemblages of Lake Taihu in 1987À1988 and in 2007 Changes in benthic communities between the two periods were significantly different among the four lake regions (the River Mouth, the North Bay, the Open Lake, and the East Bay), corresponding well with the changed environmental conditions. The River Mouth and North Bay showed the greatest changes in benthic fauna, corresponding with severe degradation in water quality. In 1987À1988, benthic communities were dominated by Tubificidae and Bivalvia in the River Mouth and the North Bay, respectively. In 2007, however, benthic fauna were mainly dominated by Tubificidae in the North Bay and total macrozoobenthos increased approximately 18-fold in abundance. The Open Lake was dominated by bivalves (mainly Corbicula fluminea) in both sampling periods, whereas an increased abundance of bivalve was observed from 1987À1988 to 2007. In the East Bay, which was covered by abundant macrophytes, the macrozoobenthos community decreased in abundance and was characterized by high species richness of gastropods. In addition, the abundance of gastropods, tubificids, and chironomids increased significantly between the two sampling periods. The relatively stable ecological conditions in the East Bay (e.g., trophic state and spatial distribution of macrophytes within the East Bay) might be responsible for the relatively small changes. Our results showed complex variation patterns of macrozoobenthic assemblages among different sections of Lake Taihu, which may be associated with the great environmental heterogeneity in this large shallow lake.
