as has been mentioned, the capture fish industry converts bycatch into fish
oil, fishmeal, & fish protein concentrate (largely for use in animal feeds).
on a small scale you might try one of the following:
grind them up along with some lower protein, lower lipid commercial pellets
to make a soft-moist pellet (keep frozen before use)
compost them--with lots of newspaper or sawdust (both cornell & univ of
maryland have information on the composting of both large animals & poultry
mortalities)

butch--
you might check a central public library, a university library, or possibly
w/fish & wildlife on the early history of fish hatcheries in america--as
"cultured" maggots was one of the first feeds used in salmonid culture

What are the manufacturers specifications? Welders and
improperly integrated ozone producing cells are considered
to produce ozone levels much higher than epa recommended
limits.
Properly adjusted and integrated ozone producing cells may
also at the immediate output but be OK a few inches away
with proper airflow and dispersion. What is the design?
NOx produced is proportional to NOx precursors and ozone
available to react with them. There is no set amount since
either concentration can vary. In other words you probably
get a lot more NOx on a street corner unless your air (or
water) is incredibly bad or you have an improperly designed
air freshener. For health info see:
http://www.eq.state.ut.us/eqamc/ozone.htm

Ozone is ozone. If the ozone reacts with ANY NOx precursor
NOx will happen. The type of equipment with no NOx output
must prevent reaction of O3 and precursors or the resultants
release. If it is so then a quality and periodic maintenance
issue is how long the input or output isolation will be
effective. Does a filter need to be renewed? For a couple of
discussions of ozone, NOx, and other air or water concerns
see:
http://www.epa.gov:80/ogwdw000/mdbp/pdf/alter/chapt_3.pdf
http://www.epa.gov/ncea/ozone.htm
If you keep in mind that air and water purification
industries in many locals are almost non regulated you can
understand the phrase "buyer beware" is highly appropriate.
Anyone can learn a few buzzwords or hire a technical writer
to do the same and generate a red hot expert sales brochure
and sales spiel but still be incompetent or even dangerous.
I personally speak with every air and water purification
vendor at every conference I go to. I am shocked at the
outright lies, misinformation or incompetence from a few!
For ozone air purification info see the EPA web site:
(also deals with fraudulent claims)

if you're going to be a large fish producer with lots of by product, then
maggot raising might be
a good answer, along with composting the remainder. There's a ready market
in the reptile and bird industry for maggots and mealworms.
Take a look at the grubco site (www.herp.com/grubco)
Once saw a very good program while we were living in England on a large
maggot farm - maggots
are used extensively as fish bait there.
Since we're very interested in setting up an aquaponics system for our bed &
breakfast, we appreciate
all the good information we receive from everyone in the group.

I would be reluctant to use the fish carcasses to feed the maggots in
this situation as the fish-maggot-fish loop seems dangerously short.
Recent history of the beef, sheep and poultry industries in the UK shows
the kind of problems that can occur with this kind of thing.
If you had another use/outlet for the maggots it may be worth using them
as an
additional stage before composting? The effect it might have on your
working environment and difficult questions from your health authority
(or neighbors) could remove any potential gain though.

Properly composted any waste can THEN be used to grow something (plant or
animal). Yes, it is dangerously close and a better way might be to compost
animal carcass to make compost to grow plants and vice versa.

That was a long time and two computer crashes ago. I no longer have that
email on file. Personally, I don't care. It's no big deal to hit the delete
button when I get back in town three weeks from now. I just thought the
moderator might prefer not to have to deal with the bounces when my mailbox
fills up.
