Abstract: | Kairomones have been documented as an infochemicals to convey information between individuals in aquatic system. However, whether the effect of fish kairomones on acceptor (zooplankton) is beneficial or detrimental is a debatable and unanswered issue. This may be due to lack of feasibility of experimentation. In this study, we theoretically explore how fish kairomones affect the aquatic food chain and provide possible explanation of such different behaviors of kairomones. To do this, we propose two hypotheses and formulate two simple mathematical models which resemble more realistic scenario synergetic with natural complex system. Our study suggests that vertical migration helps zooplankton species for proper conservation of its abundance by avoiding unnecessary over predation. |
