- | The mean size of fishes in slicks was found to be almost 30% larger than in other surface areas, probably because some larger larval fish are able to detect the accumulation of resources and indeed travel from slick to slick, whilst other large larval fish cannot detect said accumulation or choose not to travel to slicks, feeding less and hence presenting a smaller mean size. Also, since smaller larval fish are dragged in and out of slicks, some can remain feeding in it and achieve larger sizes than the ones that don' | + | The mean size of fishes in slicks was found to be almost 30% larger than in other surface areas, probably because some larger, more developed, |
