摘要:

环境刺激的缺乏是引发鱼类人工繁育苗种野外生存适应性差的重要原因。为明确在养殖环境中添加物理丰容物和捕食者是否能够改善增殖苗种的生存适应性，本研究通过双因素交互实验，探究了捕食者胁迫与添加丰容物对褐菖鲉幼鱼生长、行为和呼吸代谢的影响。结果显示：①添加丰容物能够显著促进幼鱼生长，提高幼鱼的终末体质量（P＜0.05）；长期的捕食者胁迫则抑制了幼鱼的生长，导致终末体质量、增重率和特定生长率呈下降趋势。②捕食者胁迫对褐菖鲉幼鱼的活跃性和勇敢性无显著影响，但显著降低其探索性。③在捕食者存在情况下，添加丰容物能够增强幼鱼的活跃性；④添加丰容物对幼鱼的避敌行为响应无显著影响，但长期与捕食者共存会显著降低幼鱼在风险区的累计时长（P＜0.05）；⑤添加丰容物可极显著地降低幼鱼的耗氧率（P＜0.01），而捕食者胁迫会显著提高幼鱼的耗氧率（P＜0.05）；⑥物理丰容和捕食者胁迫对褐菖鲉幼鱼的探索行为、活动水平及呼吸代谢存在显著的交互影响作用，可在一定程度上揭示环境丰容对鱼类生长与行为适应性的影响机制。研究表明，通过物理丰容与捕食者胁迫等手段开展短期行为驯化，可以有效改善褐菖鲉增殖苗种的行为适应性。

Abstract:

Stock enhancement based on hatchery-reared ?sh has become one of the most common forms of management practices in marine ?sheries resource restoration. However, a lack of environmental stimulation contributed to the poor survival adaptability of hatchery-reared fish in the wild, with negative consequences for post-release performance in the natural environments. To investigate whether incorporating physical enrichment and predator stress into aquaculture environments can enhance the survival adaptability of hatchery-reared fish, this study conducted a two-factor interaction experiment to examine the effects of predator stress and physical enrichment on the growth, behavior, and respiratory metabolism of juvenile marbled rockfish (Sebastiscus marmoratus). The findings are as follows: ① Physical enrichment significantly improved the final body mass of the juveniles (P<0.05), whereas prolonged predator stress inhibited fish growth, resulting in decreased final body mass, weight gain rate, and specific growth rate. ② Predator stress did not have a significant impact on the activity or boldness of juvenile marbled rockfish but did significantly reduce their exploratory behavior. ③ In the presence of predators, physical enrichment could increase juvenile fish’s activity. ④ Physical enrichment could not significantly impact predator avoidance behavior responses, but long-term coexistence with predators could significantly reduce the cumulative duration in risky area of the juvenile fish. ⑤ Physical enrichment could markedly reduce the oxygen consumption rate (P < 0.01), whereas predator stress significantly increased it (P<0.05) of the juvenile fish. ⑥ Both physical enrichment and predator stress had significant interaction effects on exploratory, activity, and respiratory metabolism of the juvenile fish which could reveal the mechanism of environmental enrichment on fish growth and behavioral adaptability. These results suggest that both physical enrichment and predator stress can effectively improve the environmental adaptability of hatchery-reared marbled rockfish, thereby potentially enhancing their survival performance after releasing into the wild.
