Smoking fish

I've done salmon and trout.  Alder chunks are great for smoking fish.  I try to keep temp as low as possible, around 180-200 or so.  Fish cooks pretty quickly, so if the temp creeps up the fish will be done too soon.  

Some thoughts:
How to, Fish: Smoking Your Complete Guide to Smoking Fish

Cflyinbob, this is a bit of advice I pulled from 'About Recipes' a while back:Fish: Smoking

1. The preservation of fish has been an integral part of every seafaring culture. Over the course of thousands of years of drying, salting and smoking fish the technique has developed to a point where once common food has become a delicacy. In this article let's look at hot smoked fish. Cold smoking requires temperatures of around 80 degrees F. for several days. Hot smoking however can be done at temperatures of up to 200 degrees F. and it only takes a few hours. It is best to start with a saltwater brine. The briningprocess is quick so don't worry about having to start out the day before. Plan on the fish being in the brine for about 15 minutes per 1/2 inch of thickness. Also plan on 1 quart of brine per pound of fish.

2. he brine can be simply salt and water. 2 1/2 tablespoons of plain salt, meaning salt without iodine, per cup of water. If you want to use tap water, let it sit in a large container without a lid to let the chlorine dissipate. The brine can also contain whatever seasonings you choose to add. You can replace some of the water with white wine, or you can add peppercorns, brown sugar, or any seasoning that you like with fish.

3. But what kind of fish to use? Any fish will work. However fattier fish will absorb more smoke flavor, so fish like salmon and trout are perfect for smoking. You can use whole fish or parts, but fillets with the skin still on are better than other cuts.

4. Most any kind of wood will work, but you might wish to use woods like alder or fruit woods. Salmon is usually smoked with alder, this is a tradition that dates back to the indigenous peoples of the northwestern United States. Of course you can use mesquite, oak or whatever your favorite smoke maker is. Because of the short smoke times, mesquite will not have a chance to impart too bitter of a taste, but I recommend using it sparingly.

5. If you can maintain a low smoking temperature, below 150o for the first hour or two, then the fish will have more time to absorb smoke flavor. Turn up the heat after 2 hours to around 200 degrees F to finish it off. Make sure that the fish is heated all the way through to at least 165 degrees F. Remember when it comes to low temperature cooking it is always better to be safe than sorry.

6. On a final note, I would like to point out that not only does smoked fish make a great meal or appetizer, it also makes a great ingredient. Try taking the meat from a smoked trout or similar fish and blend it together with some cream cheese, garlic, salt and pepper and you suddenly have a great spread for crackers. Many recipes call for smoked fish, from soups to salads to main courses. With the knowledge of fish smoking under your belt you will be able to make these dishes even better with home smoked fish.
