ITQ管理方案可以提供奖励，以丢弃低价值的鱼类，以便个人配额可以用于相对更有价值的鱼类。这种“高分级”也可能发生在收获受到其他限制的地方，比如储存能力。本文用ITQ和其他收获约束条件对高级化发生的确切条件进行了比较和对比。考虑到所有的成本，在物理限制下，高等级是有效的，但这是itq的不幸产物。是否会发生高级化取决于高价值鱼和低价值鱼之间的价格差异、分类和丢弃的成本以及重新收获的成本。描述了在发生ITQ高评级时纠正或减少的政策。
ITQ management programs can provide incentives to discard low valued fish so that individual quota can be used for relatively more valuable fish. Such "highgrading" can also occur where there are other constraints on harvest, such as hold capacity. This paper compares and contrasts the exact conditions under which highgrading will occur with ITQ and other harvest constraints. Considering all costs, highgrading can be efficient with physical constraints but it is an unfortunate artifact of ITQs. Whether or not highgrading will occur depends upon the price differential between high and low valued fish, the cost of sorting and discarding and the cost of re-harvest. Policies for correcting or reducing ITQ highgrading should it occur, are described.
