Oceanfish, I read your article by Parrish and Claisse. I found a few things interesting about your interpretations of this data.

"Repeated observations of individually tagged juvenile yellow tang at three sites indicated that ~30% of individuals disappeared from the specific site over a period of 5 months"

It is clearly stated in the article that this data was taken from Protected areas, how are you interpreting this as showing that the MO industry is depleting said animals by this percentage?

If the figure of 30% removal from MO collections is even close to true, and this is the same percentage that is lost from a protected area then it seems to me that the collectors are doing a pretty damned good job of not affecting the populations of these animals in any significant manner.

"The results of these studies are providing information essential for any assessment of these exploited aquarium stocks"

I find this to be a highly biased statement and it certainly brings doubt onto the interpretations drawn from the data

"However, the site with the second highest proportion of fish over 10 years old is the area open to aquarium collecting at Wawaloli Beach."

I found this to be an interesting bit of data from the study. If MO collections are so damaging, why is this the case?

The industry depleted Yellow Tangs by 47% in the Tissot study.

The Parrish and Claisse info is about mortality, life expectancy, etc..

I believe Jeremy Claisse is a huge supporter of the industry.

rgbmatt, is this a recent quote from Bob? In other words, did you contact him directly asking about his statements and receive a response?

If no one else does, I will (Rich, have you corresponded with him recently, perchance?). As I mentioned, as long as he's in country he's very good about responding quickly and if he's being misquoted or his words used as he didn't intend them, I believe he would want to be aware of it so that he might be able to clarify himself. That being said, I'm not going to ask him to read all eight pages (thus far) of this thread. I will likely simply be quoting what oceanfish has offered us and submitting that for his perusal.

Bob was speaking in Michigan his last weekend so I bet he's still in the country :)

Oceanfish,

I understand your concern about what is happening to a great percentage of marine ornamentals collected for the marine aquarium industry. However, I should say that the feedback I get from canadian fish buyers importing fish from Hawaii is that the quality is excellent and DOA and DAA are very low. Many of my customers have in their aquariums yellow tangs older than 10 years (in captivity).

The same doesn't apply to MO coming from the Philippines, Indo and other developing countries where corruption, poverty, lack of education and lack of willingness and commitment of central governments to deal with all the problems related to coastal communities and management of coral reefs.

I have seen, first hand, how terrible is the situation at community level in the Philippines, fish are killed by thousands and the ones surviving are exposed to negative conditions during extended periods of time. At this level things have improved during the last decade but there is work to be done.

Jaime

10 year old yellow tangs is good news and I'm glad to read that. But no one has been able to answer the question: what percentage of wild caught MO fish from Hawaii (or anywhere else) live longer than a year? For every one that made it to 10, how many died?

I would like to know how you tell a fish is 40.5 years old. That's a pretty exact measurement :P

Apparently they are counting rings in the Otoliths (ear bones) of the fish. Currently the researchers are assuming the rings are annual, though they admit that each ring could change in value by as much as +/- 1 year.

The oldest fish indicated in that study was 35.5, not 40.5, assuming the rings are annual.

That's right, but here's where Bushnell and Claisse document that they can live at least 40 years:
www.soest.hawaii.edu/SEAGRANT/communica ... 07/Egg.pdf
And they reported 40.5 this January.

Thats an imposable question to answer. You would have to survey every person with a fish tank.

I can tell you that in our aquariums the survival rate over the last 6 years has been about 95%. Over the last 10 years it would still be over 90%. We take care of our animals just like the large majority of other hobbyists do. We dont buy them as a folly thinking that they are expendable. They teach us respect for the environment.

If it wernt for having a reef tank i wouldn't know squat about reef ecosystems and i probably wouldn't care either. As a whole, marine aquarists really care about the reefs and its inhabitants.

If you really want to help the reefs and educate people about the plights they face the best thing you could do would be to set up your own aquarium and show it to people, explain to them how the ecosystem works, tell them why it matters.

Targeting a group of people that really care about something and trying to portray them as whimsical and uncaring about the cause i think you are trying to protect is stupid.

So is Bob Fenner, whom you also chose to quote as supporting your assertions. I happen to know the man personally, have for quite some time now, and came to know him by working this very trade you seem to detest. I'm curious as to what your point is, then, by pointing out this one person is pro-industry, and not acknowledging the other(s).

Gresham, thanks for the heads up. ;)

Lets get back to the draft legislation. What is wrong with it and what do you think is good?

Personally, I think the requirement that fish collected MUST live 180 days is nonesense. It is totally unenforceable. Whomever wrote it is using a pretense that has never been applied to any other similar legislation. In this respect, I agree with the others posting on this forum that this is poorly formulated draft legislation.

There's hardly anything to work with in this bill, where would a body even begin? Too much of the language is really quite vague. Let's hit some other points in the presented legislation:
(4) The removal of the specie does not negatively impact the reef ecosystem by contributing to algae overgrowth for herbivores, parasite overload on other reef fishes for cleaner wrasses and cleaner shrimps, or other harmful effects;
So, would any amount of "algae overgrowth" then constitute sufficient evidence for regulators to say that a given specie can no longer be collected? That language is rather vague and needs to be better qualified and quantified.

How would "parasite overload" be quantified? Any parasites? A certain number of parasites?

Who will enforce all of this? Is there already an existing regulatory body that can handle all the new paperwork and other minutiae that are required to enforce rules, regulations and laws? I see nothing here that even speaks to what body or bodies might take responsibility of oversight, or creating such a body.

Like so much legislation I read, there are more questions left unanswered than the problems allegedly being addressed.

You shouldn't take things so personally. This is a forum about an industry - not about expert or talented aquarists who have great success, nor about the conscientious who don't buy animals that don't live.

I don't think anyone is against regulation in Hawaii. If fact, just the opposite. However, I don't think that you have been promoting the idea of regulation, rather a shutting down of the industry.


I also think its disingenuous to ask people not to take things personally when many of your previous posts have been personal in tone.

FYI, this forum is defined as:
A forum dedicated to discussing industry issues such as sustainable collection techniques, legislation affecting the hobby, and industry reform.
And the forum is on a hobby site in order to give hobbyists access and input to discussion such at this.

Of course Fenner is a huge supporter of the MO industry and an expert. Below he refers to fish that have "issues". He mentions 3 species that are still collected in Hawaii: Hawaiian Cleaner Wrasse, Achilles Tang, Moorish Idol. Others collected in Hawaii are listed on the AMDA list, as "Advanced Skill required" or "Requirements unknown" (dismissed by earlier posters).

From: http://www.reefs.org/library/talklog/b_ ... 91398.html
"Some organisms are restricted in the trade (and others should be) as being considered overly exploited ( Hypsypops rubicunda , the garibaldi) or valuable to remove; such as the Hawaiian obligate cleaner wrasse , Labroides phthirophagus."...
"One outright contraindicated behavior to avoid in livestock selection is death itself; some species, for whatever unknown reasons, don't generally live through the rigors of collection, holding and shipping. Both a "clean" list of desirable species and a "dirty" list of those to avoid run very long; an ongoing compilation is available on the net at http://www.execpc.com/~jkos/amda/ecolist/ecolist2.html ; some pleasing examples are (some butterflyfishes when caught and shipped large, the saddleback, Chaetodon ephippium , the teardrop, C. unimaculata . Others rarely live any length of time regardless of size; examples include pinnatus batfish, P. pinnatus and Moorish idols; , parrotfishes, even some surgeonfishes (family Acanthuridae)(clown tang, Acanthurus lineatus) these sorts of fishes have very low initial survival records, 90+ percent perishing within a few weeks.

Part of the Hawaii legislation was an attempt to address these and other issues.

Since it's highly likely that no one has funded studies tracking the captive lifespans of MO's (why bother - they're practically free for the taking and there's an "unlimited" supply..), there's only the experts to rely on, and the lists of unsuitable species that have been created.

Please take your own advice and don't make the discussion personal with things like the above.

I think it would be great if you worked on funding studies tracking the captive lifespans of MO's.

You shouldn't take things so personally.

Why shouldn't i take it personally? You are attacking an industry i care very much about. You are also presenting things out of context.

This is a forum about an industry - not about expert or talented aquarists who have great success, nor about the conscientious who don't buy animals that don't live.

Well I am conscientious but im not clairvoyant and i have no way of knowing if an animal will live or not. You can call me an expert if you like but you will never hear me refer to myself as such. Talented? Thats debatable. Educated is more like it.

These forums are all about the sharing of information and education. If you would have taken the time to read more about the time and energy people take to setup appropriate habitats for there fish and corals instead of looking for one liners to support your cause, you would have noticed that.



Since it's highly likely that no one has funded studies tracking the captive lifespans of MO's (why bother - they're practically free for the taking and there's an "unlimited" supply..),

This is the attitude I don't like and where i feel you are barking up the wrong tree. Aquarists don't feel that there animals are expendable, unlimited, and i guarantee you they are not "practically free". We spend a ton of money on just providing the optimal environment, let alone the animals themselves. You are welcome to fund a study, no one is stopping you.

there's only the experts to rely on, and the lists of unsuitable species that have been created.

Misquotes and out of context statements don't count. You practically called me and "expert" above so why don't you use that? You can at least use it for a starting point of a study :wink:

Given what a terrible bloody industry we are...............Perhaps the government can pay the divers not to collect aquarium fish with some of this new found money that grows on trees. Sort of like paying farmers not to grow crops. Or better yet they can generate the money to pay the former collectors by putting a new resource use tax on the dive industry. New government stimulus jobs can be created collecting the money from the dive operators and disbursing it to the former collectors. The former collectors can then sit around and drink beer and smoke Maui Wowie all day. Now if they can come up with a program to pay me not to sell fish I might just take them up on it. :wink:

The real money is in the pretense of conservation.
Its a growth industry and generates jobs and income for many people now.
The amplification, exaggeration and often fabrication of basis for alarm is ..er alarming.
You know why? Because if the concern is false and the case is basically a culling of selectively Googled messages, then who is there to really care about the sea?
In Mexico there are more people monitoring, regulating and living off the industry then there are people in the industry.
They need us to justify their own new found careers. We co-operate and we humor them but its hard not to laugh sometimes because they have so little real knowledge and so little experience.
Generally they are city people and pretend to know whats best for village fishers from zero experience and less common sense.
Our main objective is to keep them from doing to much harm to innocent fisherman as they draw their regular salaries. They manipulate information and events to suit a a narrow purpose as a matter of routine.
I used to have a lot more respect for environmental folks but the new crop is by and large so very unseaworthy.

I have an idea that might work.
Why doesn't industry develop a Unsuitable Species List voluntarily.
We can start with the obvious like cleaner wrasse and Moorish Idol that everyone can agree with and add more to the list with input from hobbyists and experts and yes people like Ocean who have an extreme point of view.
The added species may not be agreed to by all but in the interest of industry survival.
Approach the government and ask them to regulate those species
Begin at the beginning. The bottom line is that we should all be concerned about the health of the reefs and the critters that dwell therein.

Unsuitable lists have been proposed (even by myself) going back over the past 20 years. They have never been something the trade wants. I would agree that this is a difficult issue, because species that are unsuitable in PI or Indonesia because they are caught with cyanide, do quite well when they are caught with nets (like the Moorish Idol, and the Regal Angelfish).

From a fisheries management perspective, all individual fish across species can be considered to have died (because they are removed from the population) whether they live or not through the CoC and in hobbyists tanks.
So, regulation is necessary, but I reiturate it needs to be across species (more general regulations to limit catches are needed).

The Hawaii Legislation (like the Federal Bill discussed by PIJAC recently) has the provision for a "clean list". If the Hawaii Legislature decided that Moorish Idols should not be collected they just omit them from the clean list.

However, the provisions for making the "clean list" like ensuring they live for more than 180 days, is unenforceable. It would serve to close down the collection of all species until studies were conducted to demonstrate that the species survived in captivity.

Naesco,

Thanks so much for your contributions to this thread.

Unfortunately, with absolutely zero past or current involvement in the trade of marine ornamentals there are some folks here is this community that might take your comments somewhat lightly.

I respect your efforts and hope that you continue to stay involved. All good teams have people cheering for them on the sidelines, out of play.

Warmest regards,
