D is the correct answer!

1.let's take a look at the modifier first； 【cutting】 their feed allotment by nearly half and 【raising】 them on special diets.   you can see the parallelism between cutting and raising. so B and E are out；

2. As for A：as 【 fast 】as their natural 【growth rate】，growth rate can't be fast. It can only be high; another example : The increase can be fast! So A is out.

3. As for C: growing them naturally; that means ab. grows the fish, so how can it the fish grow naturally?  The logic here is incorrect;

Hope it helps.

In GMAT, the same pronoun should refer to the same noun, roght?
As for D, obviously the "they" refers to suppliers and the "them" refers to fish.  Isn't it a grammer mistake?
Moreever, "fish" is a uncountble noun, can we use "them" as a pronoun of fish??
Thank you very much!

Fish is countable when speaking of the animals; the plural is normally the same (one fish, two fish), but fishes is also a plural, and is used mostly when speaking scientifically of different kinds.

so here it can be plaural.  D is the best answer among the five choices because some kind of pronoun ambiguity can be tolerated by GMAT as Ron always mentions.
