摘要: Respiration, calcification, and bio-deposition of hybrid abalone, Haliotis discus hannaixHaliotis discus discus, fed on different foodstuffs have been measured to evaluate the effect of hybrid abalone culture on carbon source/sink in coastal areas. Fed with Laminaria japonica, Undaria pinnatifida, Gracilaria lemaneiformis, U. pinnatifida, and Ulva pertusa, alternated mutually, the carbon bio-deposition rate of hybrid abalone was 24.29 +/- 6.39, 65.40 +/- 10.55, 21.48 +/- 5.99, and 29.28 +/- 6.47 mu g/g/h, respectively. Hybrid abalone fed on U. pinnatifida had a higher carbon bio-deposition rate compared to that fed on other foodstuff (P<5%). Rate of CO2 released by respiration of hybrid abalone fed on the experimental foodstuff was 24.53 +/- 8.57, 32.73 +/- 7.99, 29.31 +/- 6.39, and 33.67 +/- 12.37 mu g/g/h, respectively. Results indicated that calcification presented less relationship with body weight type of the foodstuff. The rate of CO2 released by calcification into seawater and atmosphere was 2.77 +/- 1.89 and 6.53 +/- 3.36 mu g/g/h, respectively. The total rate of CO2 released because of bio-deposition, respiration, and calcification processes was 16.19 +/- 4.67 mu g/g/h, while the total rate of carbon sequestered in shells and tissues was 8.94 +/- 2.07 mu g/g/h. The study revealed that hybrid abalone culture is a source of CO2.
