Aparentemente este estudo diz que em 2008/2009 ainda existia alguma abundância:

"Of the 22 sites registered as to where they occur, only two had water remaining..."

Sobre os peixes que ele colectou:
"I had no oxygen with me so most of the 20 collected specimens died from heat exhaustion on the journey to the Strait of the Hormuz on the Persian Gulf. We could hardly breathe in this the most intense heat I had yet encountered."

Here you can just see some of the dark blue and brown mature male Astatotilapia, and outlines of brooding females and youngesters in the spooky dark sunken forest habitat of Lake Itamba.

Lots of Astatotilapia gathered round a big sunken tree in Lake Massoko: there is a brief display by a 'floater' male showing a sort of blue-olive body colour (probably a young yellow male) and a glimpse of a big Clarias catfish.

This lake is full of wood, reeds etc and cichlids: Astatotilapia, Oreochromis (2 or 3 species), Tilapia rendalli

Astatotilapia 'massoko yellow' spawning in wild, in Lake Massoko (Kisiba) at less than 1m depth. Recorded March 2015. At the end of the clip, you can see the male eat one of the eggs.

Adult male Astatotilapia 'massoko blue' in the wild at 14-18m, defending his territory. The video shows how the camera records the natural light at this depth: it's pretty much all green.

Astatotilapia 'massoko yellow' pair courting in the wild in Lake Kisiba (aka Lake Massoko) in Tanzania March 2015. It shows how this fish isn't confined to a small territory and may not be territorial at all. They seem to be pretty opportunistic.

Agora algo diferente, uma espécie que desconhecia completamente, Ambassis sp.

Que belo cardume!!

This school of Northwest Glassfish (Ambassis sp) was filmed in a rainforest spring tributary of the Finniss River near Batchelor in the Northern Territory of Australia. Although this species is very common it remains officially undescribed. At one stage it was referred to as Ambassis muelleri which is now a synonym of Ambassis agassizii, a fish found through much of the Murray River system much further south.

Longspine glassfish, Ambassis interrupta was found in flowing freshwater stream near estuarine of one small river in North Sulawesi region.

The beautiful Barred Galaxias (Galaxias fuscus) is a critically endangered small native freshwater fish found in the headwaters of the Goulburn River in Victoria. Due largely to it's very restricted distribution and the adverse impacts of introduced predatory trout, the few remaining populations of Barred Galaxias are heavily fragmented and isolated from one another. This means that single populations are particularly vulnerable to threats from wildfires, siltation and logging, with no way of that population being re-established should it go locally extinct.

Barred Galaxias are listed as a Threatened species by the Victorian Government and as a Critically Endangered species by the IUCN. As such they are afforded full protection and cannot be taken from the wild or kept in captivity (Flora and Fauna Guarantee Act 1988). Their survival into the future depends upon the protection of the towering forest giants that surround the clear cool streams of the mountains, and on ongoing measures to stop the upstream spread of introduced trout.

Recently I had the chance to explore some of the remaining beautiful tall Mountain Ash (Eucalyptus regnans) forests which hopefully soon will form part of the proposed Great Forest National Park. I came across a small creek and after spotting a fish decided to use my gopros to try and record some footage. Although the cameras were only in the creek for around 45 minutes or so, I was thrilled to download the footage at home and see the remarkable amount of fish activity caught on camera. Using a remote camera is a bit hit and miss as often you only get a fish swim past occasionally and sometimes not at all, but any activity you get tends to be much more natural than the flurry of activity you get when a bait is used. No baits were used in this video but otherwise the technique is similar to a BRUV.

These Climbing Galaxias (Galaxias brevipinnis) were filmed in a small creek at Wilsons Promontory.Climbing Galaxias are a relatively large species that can grow to 28 cm in length, however they are more commonly seen at lengths around 15 cm. The ones shown in this video were up to ~12cm.
They are characterised by the darker patch above the pectoral fins, which like the pelvic fins are quite large and broad, an important adaption that allows them to climb waterfalls and wet rock faces, and hence colonise areas not accessible to other fish.

[youtube][/youtube]
This video shows five types of grunter (Terapontidae) found in the waterways of Kakadu: the Midgley's or Black-blotch Grunter (Pingalla midgleyi), Butler's or Sharp-nose Grunter (Syncomistes butleri), Sooty Grunter (Hephaestus fuliginosus), the Banded, Barred or Black-striped Grunter (Amniataba percoides) and the Spangled Perch (Leiopotherapon unicolor) These fish were filmed in the catchment of the South Alligator River.

The video is interesting particularly in respect to the Midgley's Grunters which show both the normal colouration (unpatterned) and the alarmed or threatened colouration (with darker horizontal lines along the sides of the body. Note that young Butler's Grunters (as seen in this video) also have dark horizontal lines along their sides which are less broken up than those on the Midgely's Grunters. Young Sooty Grunters (very common in this video) have a prominent black blotch on their anal fin like the Midgely's Grunter, however in addition they have dark markings on their dorsal fins which are missing on the Butler's Grunters.

Glowing redfins swarming among the cobbles, a speckled galaxias suspended weightless in the bubble line and a pack mottled kurpers lurking silently in the shadows. Wiley eels grin in their cavernous lairs as night sets in and their hunt begins. Large cyprinids like the Clanwilliam sandfish migrate great distances upstream to their rocky spawning grounds as the winter floods subside. A hundred years ago our fynbos rivers pulsed with fish life, but sadly those days are now long gone.

Filmed in Wilson's Promontory National Park in Victoria, Australia, this video shows the habitat or biotope associated with Common Galaxias in the very lower reaches of creeks just before they enter the ocean. Saltwater often intrudes into these areas during spring tides and storm surges.


[youtube][/youtube]
The Common Galaxias is the world's most widespread naturally occurring freshwater fish, however due to it's small size it is generally not fished for by anglers. Young Jollytails (and other Galaxiids) are often called Whitebait – they are transparent – and move upstream in large numbers where they are actively netted in commercial fishing operations in countries like New Zealand. Occasionally in places like Tidal River at Wilsons Prom, large "balls" of tiny whitebait can be seen moving upstream with the incoming tides.
