AlexJordan Posted December 2, 2011 Share Posted December 2, 2011 Hi All, I'm just back from a four month research trip on Lake Tanganyika, and have made some underwater videos of the fish and habitats in various places I visited. This is the first video of 3 or 4 that I'll upload over the next few weeks, and the footage is taken from Cape Kaku (near Cape Chaitika), Chisanza Bay (near Isanga), and Ndole Bay (near Sumbu). I hope you like it! Alexwww.alexjordan.org Link to comment Share on other sites More sharing options...

Topogigio Posted December 2, 2011 Share Posted December 2, 2011 cool video... are those fish in 1.43s & 8.51s barramandi or nile perch? Link to comment Share on other sites More sharing options...
rowie Posted December 2, 2011 Share Posted December 2, 2011 Good to see the actual layout of the lake floorCant wait to see the restCheers rowie Link to comment Share on other sites More sharing options...
lukeaaustin Posted December 2, 2011 Share Posted December 2, 2011 very very cool stuff alex. i just had a quick squiz at your page also, your pretty lucky to be involved in researching such an interesting subject which also happens to provide you with the opportunity to conduct research in such amazing places.... i'm so very jealous!Topogigo- they'd be nile perch bud, no barra over there and you can tell by the slender, kind of longer profile of the fish and the duskier colouration (until they mature and get mega!!!).luke Link to comment Share on other sites More sharing options...
AlexJordan Posted December 2, 2011 Author Share Posted December 2, 2011 Hey, thanks for the positive feedback! I study the evolution of reproductive behaviour from a social perspective - how does the fact that this girl already has a guy talking to her affect my decision to buy her a drink? If that guy is married, it must mean he's not a complete psycho, and does that make him more attractive? Except I do it all with animals (fish and spiders mostly)...I've always loved cichlids though (I've been on this board since 2001, although not too actively in the past 5 years or so), and did a field season at Tanganyika in 2008 during my PhD. Now that I've finished and can lead my own research, I've gone straight back to Tanganyika to study the most interesting fish out there. This past season I was using N multifasciatus, N buescheri, and P microlepis for my studies. You'll see more of those fish in the coming videos.Topogigo - as Luke said, they're Nile Perch, Lates angustifrons most likely, but I'm no expert on them. The massive fish at 1:30 is also a Nile Perch, and you can see just how big and deep-bodied they get (if it's not clear from the video, that fish is at least 80cm long, probably bigger - I thought it was a croc when I saw it out of the corner of my eye!).

brucem Posted December 2, 2011 Share Posted December 2, 2011 Great video Alex. I love seeing which species are mixing in the same habitat, and some of the species that we don't see in peoples aquariums.Those frontosa have such deep bodies!Looking forward to the next installmentBruce Link to comment Share on other sites More sharing options...

Saig Posted December 2, 2011 Share Posted December 2, 2011 Hi Alex, that was absolutely amazing! I kept saying wowwww.....while watching! I've been to Lake Malawi and the current was quite strong. How was the current in Lake Tanganyika?I can't wait to see the other 3 instalments!Grace Link to comment Share on other sites More sharing options...

Euan Edwards Posted December 3, 2011 Share Posted December 3, 2011 Ahh, brings back memories ... thanks Jordan not bad viz considering is was overcast & raining. I've been over the other side of the lake first Zam, then again Tanz. with the Ad man. I'll always remember being circled by a massive school of 4inch B. microlepis with the parents in view and seeing tricotis etc etc... Top job you have there Dr Fish Porn! let me know next time you need an RA on safari!EE's mate Link to comment Share on other sites More sharing options...
AlexJordan Posted December 3, 2011 Author Share Posted December 3, 2011 Hey Guys, I was only in the southern part of the lake, the farthest north I went was to the border of Congo and Zambia. When I head back to the lake next year, I'll start in Kigoma and head south along the Tanzanian coast to Mpulungu.As for crocs, there were plenty, especially when we were diving away from villages. The only way we could minimise danger was to have a good look around and make sure there were none we could actually see, and then get down to depth quickly without splashing about on the surface! Only two researchers have been attacked in the 20 years the team has been working on the lake!The lake is a pretty unpredictable beast at times, and will be calm as a mirror at the start of a dive, and then when you come up the current will be running and the swell will be right up. Generally though, the current is negligible under 5m...AlexCrocsCurrentSouthern Link to comment Share on other sites More sharing options...

efc01 Posted December 3, 2011 Share Posted December 3, 2011 Awesome work Alex.Any chance of trips into the Congo?Also if you could but the vids on a dvd im happy to donate $30 to your research fund! Probably have another 5 people interested.Pm me if this interests you.Nick Link to comment Share on other sites More sharing options...
Link2Hell Posted December 3, 2011 Share Posted December 3, 2011 Alex I enjoyed your 3 minute thesis and congrates on winning thecompetition............ people check Alex's site for the presentationwell presented and get a laugh as a bonusChris Link to comment Share on other sites More sharing options...
AlexJordan Posted December 5, 2011 Author Share Posted December 5, 2011 Heh, thanks Chris!Nick - it's possible to take boats along the Congo coast, but obviously you need someone with you who knows what they're doing. Apparently Uvira is fine for foreigners, but of course, the Lake in that area and around Bujumbura is probably in the worst condition of anywhere, so no real point diving there when alternatives are available. I'll have a think about a dvd after I've made all the videos.Alex Link to comment Share on other sites More sharing options...
Ged Posted December 5, 2011 Share Posted December 5, 2011 Great video and a very interesting research project. What impressed me the most was the population density of some of the species. I know we often talk about increasing the stocking rates of our tanks to distribute the aggression but what occurs in nature has made me rethink a few things. Now to find a larger filtration system. I will also have to email Ben for a copy of the research paper on Cape Honey Bees. Link to comment Share on other sites More sharing options...
