shoals seem to NOT regenerate once completely depleted
is this by design? tutorial says nothing to that effect, and at the very least there should be some warning message when nearly depleted
worse, a fishery often accesses several shoals (so one reachs zero while others still have plenty of fish remaining), and there is no way to instruct which shoal should be fished and which left to regenerate -- especially since one shoal can "belong" to multiple fisheries (it seems that a shoal can replenish faster than 1 fishery can exhaust it, but it's not always possible to position the fisheries so that each covers exactly a single shoal)
i have a shoal that is fished by 1 fishery, replenishes as fast as fished, never depleted
but another nearby shoal also fished by 1 fishery, replenishes far slower
why? (original/current size of shoal? all this should be explained)
