No thanks for the hobby?

[KrisReef]

I was just nosing around and saw this article about Captive Grown Yellow tangs being released into the wild in Hawaii.

The technology and science was driven in part by the hobby, but we get no thanks. I also agree with the authors concerns discussed at the end of the article.

OI Release 300 Aquacultured Yellow Tangs into Hawaiian Waters | Reef Builders | The Reef and Saltwater Aquarium Blog

The Oceanic Insitute of Hawaii Pacific University has released over 300 juvenile aquacultured yellow tangs into the waters of Oahu, part of the Hawaiian island chain and home to the State capital…

Yeah. The end of the article makes a very good point

I would be less concerned of disease, and more worried about introduction of genetic "anomalies" into the wild population. Maybe if they were going extinct it would be worth the risk.

I don't think there's going to be a substantial amount of genetic drift to be of any consequence. It is true that there are different evolutionary pressures between Captive Bred and Wild tangs, but there hasn't been enough time for significant generational change between the two groups. Also, the levels of survival instinct are still going to be the same. CB tangs are still going to search out and eat what they can find. And it seems to me that grazing, compared to active hunting, makes survivability a foregone conclusion in this regard. Now, I can see an argument with disease states affecting the CB tangs more so than the reverse, affecting CB almost exclusively.

I think it's a good effort. I WOULD NOT support moving a significant population from one point to another. While there may be some positive outcomes in one area, the other would end up with a deficit and all the issues that come with it. Interesting article!

I think the issue is removing 12,000 for the hobby from one place and adding 200 captive bred to another doesn't make sense

Sorta like releasing prisoners into the backwoods of Montana

Oh, I see that. And I may have missed that. I tend to read articles from back to front. Helps in some areas, but I tend to miss in others.

I feel like it's because we take more than we give

I have experience with Fish and Wildlife in California and used to keep up with the scientists who were supposed to be managing fisheries and out planting of a few species including white seabass and abalone. I have also crashed my own reef a few times and with what I know I cant support the out planting described in the article.

If the area described was totally isolated from wild tang populations it might be a kind gesture to boost the local population but the risks I have knowledge of that have been hidden from the public tell me to stop this kind of activity and let nature resupply local stocks if they are lean.

The two entities doing this out planting are likely to do more harm than good. They could have given those few hundred tangs to LFS on the mainland as a sign of good will to prevent wild harvesting and not have risked a serious introduction of negative consequences that nobody wants.

Author Jeremy Gay was much kinder than I could have been.

Not all Wildlife Management efforts are equal. I do think California has taken a positive step to help support Salmon to survive in the wild by spearheading (with others) the removal of dams on the Klamath River. The fish have been observed spawning in riffles where for 100+ years a dam had flooded the habitat. They are also still messing with hatchery fishes but bad habits are hard to break. ( I need a cigarette.)

For more wisdom on Salmon management and genetic populational science see this excellent book:

And this is where I'm terrifically weak. I'd absolutely love the kind of experience you have. My first love in terms of study was Biology and how it is reflected environmentally. But I sold out and got my degree in Pharmacy, as I wanted to make a good living and I was under a time crunch. I could have made Biology work if I'd not gone on in College x7 years with no real direction. LOL, I just loved academia.

Are you a compounding pharma guy that I have been looking for? I know a guy near me who is a pig farmer and when I looked at your avatar I didn't put this all together.

I didn't have a real direction for college either, and my own experience was to drop out and then re-enter college many times in many institutions. I had a love-hate relationship with the academy. I love knowledge but struggled with wisdom more. Academia should be required to take a 2 year advanced course in wisdom before they are allowed to teach.

It has been the lack of wisdom (in my experience and observation) that makes education a disaster for the many youngsters who want to improve their world and they get warped in the academy into thinking they have all the answers.

There will be a test later.
