| 摘要: |
| 为研究不同环境因素对紫贻贝(Mytilus galloprovincialis)幼贝足丝分泌的影响,选取山东省日照市养殖区的紫贻贝幼贝为研究对象,通过区组设计分别进行不同温度(17℃、22℃、27℃)和盐度(20、25、30),不同光照(10、100、10 000 lx)和饥饿(0、24、48 h),不同干露(0、24、48 h)和氨氮(0、15、30 mg/L)条件的2因素交互作用实验。结果显示,温度和盐度均会对紫贻贝幼贝足丝分泌产生极显著影响(P＜0.01),在实验温、盐条件下均呈显著弱负相关(R=–0.11/–0.16,P＜0.05),其中温度27℃、盐度30%组别在不同时间点的紫贻贝幼贝足丝分泌能力显著低于其他组别(P＜0.05)。光照对紫贻贝幼贝足丝分泌产生极显著影响(P＜0.01),呈现极显著弱相关(R=0.14,P＜0.01),而短期饥饿对紫贻贝幼贝足丝分泌影响不显著(P＞0.05),低光照组(10 lx)紫贻贝幼贝足丝分泌能力显著高于其他组别。干露和氨氮均会对紫贻贝幼贝足丝分泌产生显著影响(P＜0.05),其中干露与紫贻贝足丝分泌显著弱负相关(R=–0.09,P＜0.05),而氨氮则显著负相关(R=–0.45,P＜0.05),高氨氮(30 mg/L)和干露(48 h)组合紫贻贝幼贝足丝分泌能力显著低于其他组别(P＜0.05)。研究结果可为紫贻贝的苗种转运、夹苗和健康养殖等生产实践提供有益参考。 |

| Abstract: |
| To study the effects of environmental factors such as temperature, salinity, light, starvation, exposure to air, and ammonia-nitrogen on the productivity of byssus in Mytilus galloprovincialis, the juvenile blue mussels obtained from the cultivation rafts of Rizhao, Shandong Province were selected as research subjects. The two-factor interaction experiments between different temperatures (17 ℃, 22℃, and 27 ℃), salinity concentrations (20‰, 25‰, and 30‰), light intensities (10 000, and 10 000 lx), starvation times (0, 24, 48 h), air-exposure durations (0, 24, 48 h), and ammonia-nitrogen levels (0, 15, and 30 mg/L) were conducted using block design. Both temperature and salinity significantly impacted productivity (P < 0.01). Byssus production in the 27 ℃ and 30% salinity group was markedly lower than other groups at all time points (P < 0.05). Within the experimental ranges, temperature and salinity showed a significant weak negative correlation (r = −0.11/−0.16, P < 0.05) with byssus production. The light had a remarkable impact on byssus production (P < 0.01), whereas short-term starvation had no significant effect (P > 0.05). The dark group (10 lx) demonstrated a markedly elevated production of byssus than other groups; there was a weak correlation between light and byssus production (r = 0.14, P < 0.01). Air exposure and ammonia-nitrogen remarkably negatively influenced byssus production (P < 0.05). High ammonia-nitrogen (30 mg/L) and prolonged air exposure (48 h) significantly constricted productivity (r = −0.09, P < 0.05). These results can provide useful references for the practices of seedling transportation, clamping, and healthy cultivation of blue mussels. |
