A changed post-flood management strategy enables the culture-based fishery of the Liangzi Lake, Yangtze River Basin, China, to remain economically and environmentally viable Q Wang (4703689) Z Li (774829) M Lin (7837667) S Ye (7645880) W Li (7678928) C Guo (7947251) G Huang (7750961) J Yuan (3293145) J Liu (805042) SS De Silva (14472243) Agricultural, veterinary and food sciences Environmental management Ecology Fisheries sciences Applied economics Science & Technology Life Sciences & Biomedicine Fisheries culture-based fishery flood macrophyte nutrient removal stocked species Yangtze River Basin CRAB ERIOCHEIR-SINENSIS MITTEN CRAB FLOOD IMPACT 3 GORGES AQUACULTURE TRENDS COMMUNITIES ECOSYSTEM GEZHOUBA CARPS Q2 The culture-based fishery of Liangzi Lake, Yangtze River Basin, established in 1992, yielded 2,652 t/year (±167) between 2005 and 2015, dominated by stocked carps [Hypophthalmichthys molitrix (Val.) and Hypophthalmichthys nobilis (Richardson)] and mitten crab Eriocheir sinensis (Milne Edwards), accounting for 53% and 23% of the production and 20% and 52% in value, respectively. The lake had a macrophyte cover dominated by Vallisneria natans (Lour.) Hara with a cumulative biomass of 10,647 g/m² that disappeared after a major flood in 2010 and changed its ecology. Management changes in stocking strategies introduced in the post-flood period enabled the culture-based fishery to maintain viability and sustainability to combat the major ecological change in the lake. The stocked species contributed significantly to nutrient removal of 24.71 ± 5.12 t/yr and 6.29 ± 0.87 t/yr of total nitrogen and total phosphorus, respectively.<p></p> 2019-12-01T00:00:00Z Text Journal contribution 10.26187/deakin.34030149 https://figshare.com/articles/journal_contribution/A_changed_post-flood_management_strategy_enables_the_culture-based_fishery_of_the_Liangzi_Lake_Yangtze_River_Basin_China_to_remain_economically_and_environmentally_viable/34030149 All Rights Reserved Restricted Access
