game.Players.PlayerAdded:Connect(function(plr)
	wait()
	local plrkey = "id_"..plr.userId
	local save1 = plr.leaderstats.Fish
	local save2 = plr.leadersats.Pearls
	
	local GetSaved = ds:GetAsync(plrkey)
	if GetSaved then
		save1.Value = GetSaved[1]
		save2.Value = GetSaved[2]
	else
		local NumberForSaving = {save1.Value, save2.value}
		ds:GetAsync(plrkey, NumberForSaving)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	ds:GetAysnc("id_"..plr.userId, {plr.leaderstats.Pearls.Value, plr.leaderstats.Fish.Value})
end)

Hope You Can Help!

You're error is at Line 19

you put "GetAsync", instead of "SetAsync", and when it's trying to GetAsync of the saved data, there's none cause your not saving any.

here's your fixed code:

local ds = game:GetService("DataStoreService"):GetDataStore("SaveData")
game.Players.PlayerAdded:Connect(function(plr)
    wait()
    local plrkey = "id_"..plr.userId
    local save1 = plr.leaderstats.Fish
    local save2 = plr.leadersats.Pearls

    local GetSaved = ds:GetAsync(plrkey)
    if GetSaved then
        save1.Value = GetSaved[1]
        save2.Value = GetSaved[2]
    else
        local NumberForSaving = {save1.Value, save2.value}
        ds:GetAsync(plrkey, NumberForSaving)
    end
end)

game.Players.PlayerRemoving:Connect(function(plr)
    local key = "id_"..plr.userId"
    local DataToSave = {plr.leaderstats.Pearls.Value, plr.leaderstats.Fish.Value}
    ds:SetAysnc(key, DataToSave)
end)

Hope this helps :)

Spelling error you did GetAysnc instead of GetAsync
