Thanks for posting! We also have a huge problem in Southern Africa, as introduced basses, trout and carp are basically taking over and wiping out indigenous fish species. The biggest obstacle we have in remedying the problem is the recreational sport fishing fraternity who by and large don't really care so long as they can catch and release their favourite alien exotic invader species.

BTW the best way to remove bass is during the spawning season, when you can catch the big ones and breeders easily by dragging a lure such as a spinnerbait through their nests. Carp are best removed by netting them when they gather near river inlets to spawn in early Spring.

@@majorbruster5916 Thank you! I used to be a strict catch and release angler in line with the Bassmaster ethos until I discovered just how destructive exotic alien fishes are to the ecosystems in which they were introduced. One of my "hopes" is that more recreational anglers would help in removing them so as to give the natives a fighting chance at survival. Carp are especially damaging to biodiversity and tend to take over completely after a while, and if every one of the millions of anglers removed just a few every season it would go a long way towards remedying the situation. Granted it is very difficult to take out all of the aliens once they are established, and certain enclosed waters could remain designated bass or carp waters where sport anglers could do their thing - but everywhere else they don't belong, they need to be removed. A few solutions include electro barriers in streams and rivers that still hold reasonable numbers of native fishes to prevent the expansion of aliens. A small river or stream could be diverted in stages and selectively netted out prior to the installation of the barriers. Commercial netting licences can be granted to fishermen who would net out the bad guys and release any natives. This works well in Utah for example, where the carp are sold to ensure that costs are covered. In Africa, the less privileged would really appreciate a source of good protein - carp are actually great eating when prepared correctly. Have a good one and thanks again for your support.

I live on the other side of the Iberian Península, similar latitude, just next to the Mediterranean. I live right next to a small river, most of you would call this a small stream due to the little amount of water it carries year around, which is now continuously drained for irrigation but then refilled by waste water treatment plants. The river is home to a species of fish (Squalius valentinus) that only lives in a handful of rivers in the region. The regional government does not even includes it in the list of protected species, meanwhile it confronts dessication, competition with invasive species, pollution and habitat destruction on a massive scale. Iberian rivers are a silent dissaster. Thank you Rodrigo for making this tiny documentary.

Fantástico, este documentário só peca por tardio e curto, deveria haver mais esforços por manter estas espécies vivas porque é muito triste perdê-las, mas sabemos que é quase impossível mesmo que houvesse milhões disponíveis para tal. Vivo em Trás-os-Montes, aqui há (em declínio abrupto) todas as espécies relatadas no vídeo, mas os rios estão invadidos pelas espécies invasoras relatadas. Neste verão visitei o Lago de Sanábria e lá parece que ainda é um santuário, pois havia grande quantidade de Bogas Portuguesas, Bogas comuns, Escalos do Sul, Barbos… É interessante mergulhar naquelas águas cristalinas, pois temos o prazer de ser acompanhados e rodeados de muito perto por estes peixes. Foi-me relatado que já há Lúcios nesse lago, nos mergulhos que dei não vi sinal deles, mas era de admirar não haver, é uma questão de tempo. O filme foi muito bem realizado, a narradora esteve top, principalmente quando pronunciava os nomes em português.

@@majorbruster5916 They refer to a literature record from 1927, but that was long before holbrooki got species status. Back then, both affinis and holbrooki were lumped together as a single species. Note that the Italian populations are derived from the Spanish ones and also note that Vidal argues that all populations in Europe should be referred to as holbrooki unless new evidence is provided. - It would be extremely interesting if someone checks the Hungarian population because it is very isolated, non-Mediterranean and might have a different origin from the others ...

i am sorry, but i find this video quite misleading and actual spreading disinformation, statements such as widespread and in every river basin are used carelessly throughout the video, if you look on reports and and actual areas where some of the invasives are found, they are limited to the south, unless the authors consider Portugal as only Lisbon and the south, i would rather they corrected the video to ensure it is accurate, unless they just want to scaremonger and maybe find funds.
@risilva
@risilva 29 күн бұрын
We did look at the reports. The only invasive restricted to the south is the chameleon cichlid, as we mentioned. Yes invasives are in almost every river basin. There was no financial incentive, the video was produced at a loss. Spreading negativity on a video that was completely free for you to watch and is actually raising awareness.

@risilva its not negativity. Can you find lepomis in Douro? Or in Lima or Minho? The video is great quality, but generalising does not help. Even in Nabao, i always look for fish in there never found any of these species. Not saying it is not an important problem, but if trying to make a video as scientific we should tey to be accurate. Meant as positive criticism, not negative
