TwoTankAmin, Yes, exactly the problem with illegal traffic of species and I could add many more issues that follow with the illegal traffic, that is one reason it is necessary to improve the legal activity and the legal activity will not be improved without more and new species to offer. UN report ...

TwoTankAmin, Not sure how you are thinking, but the amount of fish per species collected and exported is not high, ~90% of all fish collected and exported are from the yearly reproduction, ~95% of the yearly reproduction do not reach maturity and reproductive size by natural causes. Numbers per ...

TwoTankAmin, The answer are no on all your three questions. It does not exist any “approved list”, all species that legally can be collected and exported as ornamental fish must be scientifically described and not listed in any state or federal list of species under research/investigations that by pr ...

I have been working with ornamental fish export from Brazil over 10 years, worked to improve the activity and implement some wild fishery managements but it is difficult. For me it is ethical if I remove a fish with 30-40 or even 50 years old from nature, even if it not harm the population of the ...

Conclusion: the production in this study appeared to be profitable on smaller scales, however the profitability of large-scale production depends upon reducing expenses and increasing the selling price. There is the big zebra farm, Cv. Bellenz. There are more than one and Cv. Bellenz are not the ...

This article only show how low the knowledge are in Brazil when it comes to reproduction of ornamental fish, they have no idea about the market, values, production and what is needed to reproduce on a commercial scale. There are many wrong information in this article and it is not based on research ...

Malnutrition, lacking some nutrients and it does look to thin too, try variate the food and make sure it eats well.

I don't think any H. zebra was killed in this study, the H. zebra was donated by INPA in Manaus and probably origin by confiscation from traffickers. They used crude carp pituitary extract to rip males from semen.

The CITES listing made no difference, the illegal traffic has continue as usual to Peru and Colombia. Is no real data by research published yet, but the upper locations in Volta Grande (close Pimental) the population has declined so much that even the fishermen no longer put effort to collect the H ...

Unfortunate, H. zebra are popular among researchers and students in Brazil, even if they can use another species of Hypancistrus for this kind of research to reach the same results, their first option are always H. zebra. Using hormones does not work for Hypancistrus since they get easily damaged ...

ICMBio need to re-evaluate these species in the endangered list that not are endangered, maybe make the same they did before December 2014 by inviting +1000 researchers in Brazil to answer a questionnaire of 5 questions if I remember correct, for species they thought should be in the new endangered ...

This list are old and not valid http://www.ibama.gov.br/areas-tematicas-recursos-pesqueiros/listas-de-especies-de-peixes-permitidas-aguas-continentais/tudo They have not updated their homepage, the last and valid permitted list are INI n1, de 3 de janeiro de 2012 - Ornamentais. CITES app III don't ...

This makes me wonder more about the potential cause or causes. No only is there the question of what causes snubbing, but also, what determines the severity of any individual case?

Different levels of disturbed cell growth in early stage, I believe.

Janne

I hatched eggs artificially and got snub nosed too, I produced many thousands of pleco's and still do and I have never seen any snub nose at larvae stage, for me the deformation have always appeared under the last days before or right afetr the fry consumed the yolk sac.

Janne

Long time since I replied here but I try to check from time to time interesting topics. Yes, there are snub nosed pleco's in the wild, we receive from time to time few individuals that are snub nosed, can be Hypancistrus, Spectracanthicus or other genus/species, I would not say it's common but does ...

Thats the famous Volta Grande, a really impressive place and simply huge in dimensions. Definetely one of the most beautiful places I have visited so far. I have not seen any other place like Volta Grande, it should have been classified as a World Heritage Site for many years ago, maybe that could ...

The first would be that the authorities in Brazil have finally managed to figure out how to stop the illegal trade. No. More likely would be activities related to the dam project have made it more difficult for the collectors to work unseen. Yes, but also impossible when no one can see the fish to ...

However, it's necessary to have a better regulation and for me I would want to see some kind of international certificate for exporters, they need to fulfill some criteria to be able to export wild collect fish, I think this would be an excellent idea, if it is possible in practice. It is, WWF and ...

I have read through most pages in "DRAFT CONSULTATION PAPER" and there are many wrong facts, they need to make a new one 2014 and use the correct reference. I even found a reference that was cought for illegal activities involved in the business. If we go back some years part of what is written was ...

Partially what made me reply to the original poster was that I've been seeing a larger range of "L" numbers for sale locally (Bath/Bristol in the UK), and extrapolating from that (to a world wide scale), and building in ?50% mortality during capture and transit it made me wonder what is the total ...

You can find loads of examples where we carried on harvesting animals for a long period without any apparent diminution in supply, but only because there was a very large population to start off with. I don't expect that the Maoris ever expected to run out of Moas, or European fisherman Cod in the ...

If you use this approach to whether fish collection from the wild is likely to be sustainable for any species, and to me it would strongly suggest that fish like large Panaque spp. are being "strip-mined" from the Amazon basin at unsustainable rates. No they are not and they have a very high ...

Have lost 2 of my full grown L191 Panaques (Dull eyed Royal) in last few months with no obvious cause or reason behind it. I'm not exactly sure of their age but between 9 and 11 years, so I'm wondering if it was just old age. Has anyone any experience of what a reasonable captive life span for ...

It can be this one too, since he is located in Brazil we don't need to import common pleco... they are everywhere.

Janne

Firstly, vitually all South American waters are below 100 micro Siemens. Not completely true, in general for the lowland amazonas but absolutely not for the whole South America. Obviously, you would need to have water which is pure enough - that is, quite free of nitrates and so on. But assume 10 ...

According to Fishbase A. hoplogenys are found in Uruguay.

If that is true (I have not checked) is just another mistake among many in fishbase, use fishbase as a guideline but not as a truth.

Janne

Do you mean the ones imported as agaboensis are L180? Not really, it can be L032 or L180 because the supplier of this fish have no idea and there are no 100% information of collecting locality, they can look very similar. Which pic are you referring to? Not in any picture posted her. So my unknown ...

First, when Brazil made the new permitted list of species for export they more or less excluded all Ancistrus species except a few ones, of these 4 species is easy to distinct (L34, L059, L183 and L255) and the rest is brown species looking similar... total 7 species (3 brown ones) of Ancistrus is ...

There are 2 genus in the pictures, the one in front is Peckoltia and the one in the back is a Hypancistrus, what they are I dont know.

Janne

It's not uncommon in nature either, many species of pleco's grow "extra" long fins but the environment is harder for the fish, in an aquarium they are more protected special if they are alone in a tank. Most plecos we collect in nature have damaged fins somewhere, shorter or smaller than if they was ...
