拥有战术而没有战略的方法，就像是在黑夜里乱开枪，你也许会得到一些猎物，但是并不能够持续收获。 这种方法也不会提供给你一个继续收获的方法。
A system based on tactics without strategy leads to shooting in the dark—you might get something done, but it doesn’t become sustainable or provide you with a path to continue on.
这一点很重要，因为理论表明，当目标鱼种的生物量为其原始水平的50%左右时，渔场才能达到可收获的最大可持续产量。
That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels.
另外，随着生产地区收获季节的来临，蔬菜价格持续下降。
In addition, vegetable prices have continued declining with the harvest season under way in major production regions.
