In this study, two experiments were conducted with different bait specifications (live artemia: 2215 ± 51.8 µm, 5080 ± 83.6 µm, 8440 ± 114.1 µm and their combinations) and bait types (live artemia and chilled bran shrimp). The results showed that 8440 ± 114.1 µm of live artemia was the most suitable bait by observing the sensitivity of hippocampi to bait and ingestive parameters. The sensitivity of live artemia to bait and ingestive parameters were significantly higher than those of chilled bran shrimp. In conclusion, the ingestive behavior of hippocampi was affected by both bait specifications and bait types. In the suitable bait specifications and types, the hippocampi were active in ingestion, highly sensitive to bait and the ingestive success rate was significantly improved.展开更多
