Release weights

<< < (2/3) > >>

Jamie Moir:
Ditto for venting being really risky.

I think my first release weight was a big snapper sinker with a crushed barb hook held on with a wormdrive clamp. It would be pretty easy to make something out of some SS wire and a big bomb sinker.

Locally the dhufish are pretty crap for release, but if you take it easy, and fish light, they can come up ok.



Like Kasey says though, best to go do something else once you have enough fish for the day because they're release candidates.

I just saw your post regarding jigging large groupers out of 40-80m of water. In this case you may need more than a brick to send them back down. Even then, due to their sedentary nature, groupers are not highly evolved to deal with barotrauma and suffer terribly for it, unlike pelagics. I do not suggest jigging for groupers in deep water (including coral trout) unless you intend to eat them. The mortality rates for catch and release of these species are highly discouraging and I would try to dissuade anyone specifically going out to target them for this purpose as it would almost surely result in high mortality rates of old, breeding fish.

Hi Casey

Thank you for your reply.

I have found some "articles" on web, that describe what affects the mortality rate,  eg. hooktype, surface interval, use of venting tool etc. Do you or anyone here know a good web source of were to learn more. 

Do anyone here have experience releasing Doggies, as I have learned that they also tend to suffer from barotrauma.

Regards
Mads

Kasey Leong:
Mads,

As I mentioned, the species of fish will probably also play a critical part. Pelagics, like marlin or swordfish can dive down to hundreds of meters and come up with little signs of barotrauma, whereas demersal fish especially groupers can be brought up from 30m with guts, eyes and swim bladder protruding. That is on the barotrauma side.

Doggies may not suffer so much from overinflated swim bladders, but they are almost useless releasing as well. From what I understand, they basically fight themselves to death, but I will leave this to others who have more experience with doggies to comment.

Brandon Khoo:
doggies also suffer badly from barotrauma and as Kasey wrote, run themselves into the ground till the lactic acid build-up is such that they struggle to swim away at all. The mortality rate would be very high with these

Andrew Cox:
Not to many people try to release grouper, bass, hapuka and the likes as the success rate is very low, if we didn't jig a few of these species up every year you have no idea the amount of damage they do, try sending a 15kg kingie down as a live bait and see how long it last, I sure no I would rather thin the grouper, bass and hapuka out so we can jig kings for years to come rather than the other way around.
What surprises me is that on most trips only 10-15 of these species are caught to take home, the rest of the time we target kings, but if you look at the size of the fish we are coming up with I am glad we are thinning them out, how many fish would a 40 + kg bass that regularly gets caught eat in a week, also these fishers like the Three Kings are not fished all year like some spots but only three months of the year.
I am sure if top water fisherman had the chance to catch these fish on poppers they would jump at the chance.
