FYI, interesting article. Hybrid marine fishes, new Tridacnid sp., all
white clowns 2/5/09 Hello WetWebMedia
crew! <Hello Kai> I read this article today at my local forum, and
thought it might be interesting to share with you guys. I am unsure if
you guys have already read it, but no harm in sharing right? :) I am
also unsure on how true this information is, and also how old this
information it. Forgive me for the long e-mail. The link for the article
was not provided so I will just copy and paste it here =)Scientists
discover marine hybrid hotspot Scientists from Australia have discovered
a hotspot in the eastern Indian Ocean where unusually high numbers of
natural hybrid fishes occur. The team from the ARC Centre of Excellence
for Coral Reef Studies, at James Cook University's School of Tropical
and Marine Biology in Queensland, found the hybridisation hotspot
between the Christmas and Cocos Islands. Marine hybrid fishes are
generally considered quite rare, but the area between the islands is
home to a massive 11 reef fish hybrids spanning six different fish
families - the highest number of hybrids ever recorded at a single
location. In most cases, at least one of the parent species that form
the hybrids is a rarity at the site, with less than three individuals
found over an area spanning 3000 square metres. The scientists believe
that the scarcity of potential mates mean that the fish are breeding
with closely related species, rather than with their own kind. The
authors said: "These islands also represent a marine suture zone where
many of the hybrids have arisen through interbreeding between Indian and
Pacific Ocean species. "For these species, it appears that past climate
changes allowed species to diverge in allopatry, while recent conditions
have facilitated contact and subsequent hybridization at this
Indo-Pacific biogeographic border. "The discovery of the
Christmas-Cocos hybrid zone refutes the notion that hybridization is
lacking on coral reefs and provides a natural laboratory for testing the
generality of terrestrially derived hybridization theory in the marine
environment."The hybrids found at the site include: Acanthurus
leucosternon x Acanthurus nigricans Naso elegans x Naso lituratus,
Melichthys indicus x Melichthys vidua, Chaetodon guttatissimus x
Chaetodon punctatofasciatus Chaetodon ornatissimus x Chaetodon
punctatofasciatus Chaetodon ornatissimus x Chaetodon meyeri, Chaetodon
lunulatus x Chaetodon trifasciatus, Thalassoma jansenii x Thalassoma
quinquevittatum, Centropyge flavissima x Centropyge eibli, Centropyge
eibli x Centropyge vrolikii Centropyge flavissima x Centropyge vrolikii

border. Biol Lett. 2008 Dec 23.I really hope this long e-mail will not
crash your system or anything....just wanted to share this with you,
as you guys have helped me so much before, I feel i should let you read
this for some relaxation and perhaps you might find it interesting :)
Did you also know a recently discovered Tridacna species have
been...well...discovered? Tridacna costata. I wiki-ed it and it says
that it has been around for very long...but has now gotten extremely
rare. Oh and yea....ORA is trying to breed the world's first pure white
Clownfish....Well, they are almost there..Pure white with a little touch
of orange left on the tips of the fins. Hope you enjoy the "recent"
news. I am unsure how recent this is, maybe I have been under the rock
all this time =) If your system crashes because of this loooong mail,
I'm sorry hehe. Regards <Have not read, but interesting. Thank you
for sharing. James (Salty Dog)> - Kai.
Re: SW captive breeding 7/4/08 good day >Rotimi< Aside from
clown fish i would like to know 1 names of other marine fish that
can be bred commercially in captivity. <See here:
http://wetwebmedia.com/AqSciSubWebIndex/orncultart.htm and the linked
files above> 2 books or other materials on how to breed them and
<... You have Frank Hoff's books? Have seen the new one by Matt
Wittenrich?> 3 good sources for obtaining such adult fish for
breeding thank you <These are all over the world... best to buy
juveniles, raise yourself. Bob Fenner>
Mullet culture, fingerlings source 3/19/07 Note: add family...
Dear Sir: I am Maryam Jorjani and am working Golestan Fisheries
Research Center in Iran. we are researching about propagation and
larviculture Mugil cephalus. now we do not have this fish and we need
to provide fry / fingerling. do you know person that help us?
Thanks a lot .and I am waiting for your reply Maryam
Golestan Fisheries Research Center Gorgan Iran
Tel:+981712222601 Fax:+981712240290 <Pleased to meet you. I
did work on this Mullet species' aquaculture years back... but I don't
know where you can commercially purchase young. According to
fishbase.org:
http://fishbase.sinica.edu.tw/tools/aquamaps/receive.php M.
cephalus range extends into the lower Persian Gulf... Could you collect
it from there? (the young are easily seined in shallow water where
found. Bob Fenner>
