- | ===== Introduction ===== | ||
- | |||
- | Many marine fish begin their life at ocean surface, where they live for days to weeks, feeding mainly from zooplankton until its development is complete. The availability of such resource is therefore fundamental for these marine fish species' | ||
- | |||
- | Surface slicks are meandering lines of convergence on the ocean surface, usually formed by wind and internal waves, that accumulate zooplankton and other microorganisms, | ||

- | However, these surface slicks also tend to accumulate micro plastics that are often mistaken as food by larval fish. Currently slicks contain a ratio of about 7:1 of plastics: | ||

- | ===== Assignment ===== | ||
- | |||
- | Propose a mathematical model for the fish population, incorporating the effects of resource and plastic accumulation in slicks and also the possible harmful effects plastics may cause in fish population. | ||
- | |||
- | ===== Questions & Suggestions ===== | ||
- | |||
- | * We suggest you to focus on larger larval fishes, as they can actively search, or not, for slicks. ** I think it would be instructive to point the readers out to model the ones that are able to choose whether to be or not to be in slicks, since this is the behavioral aspect of the problem** | ||
- | |||
- | * Could larval fish maintain plastic levels in surface slicks under control due to their accidental consumption? | ||
- | |||
- | * Could fish adapt to avoid surface slicks due to plastic accumulation? | ||
