You're going to find it hard going to find helpful info on sport fishing @flybri but enjoy Rio anyway! It's a fun & beautiful city. Watch for the huge groups of Frigate birds that hang over the beaches and collect in enormous spirals on the air currents just before thunderstorms. And if they join the other birds diving somewhere in the bay then you know something interesting is going on underwater.
There are Robalo (local name for Snook) all along the coast of Rio state and if you take a boat out towards the islands you can see from Ipanema beach (the
Cagarras) then I know people that fish around those - not cheap though. People fish from the city beaches but mainly for small stuff & squid using bait. They lure fish from the end of the big rock that separates Ipanema from Copacabana beaches (
Arpodor) but it's bloody dangerous especially at night with waves washing up over slippery rocks with ill-defined edges and treacherous rocky sea waiting for you way down at the bottom if you do slide off. Lovely view though! Take care if you try it and you'll need to fit into the ranks as it's very popular. From there I have seen big shoals of Espadas lit up by the beach lights at night as they come out of the water attacking the bait fish. They are long thin predators with iridescent silver bodies - like a very large and flexible Garfish but with fearsome teeth. When they are landed (usually on plugs or spoons) they are despatched quickly and brutally.
The cliff walkway at cliff end of
Leme beach is also popular but much safer with rails and doesn't get wet in the same way as it's much higher above the water. Also popular with bait fisherman who target small stuff and squid. Take a drop net or a sturdy rod.
I think in general that if you want sport fishing you'll need to hire a boat and get offshore. There are certainly Albacore, Bonito, Amberjack and other Pelagics there so if you see fish jumping or birds swooping get there ASAP and chuck a big clouser in. Make sure you have a good reel and plenty of backing though if you do find yourself in that happy situation...
This page is very good for identifying the Brazilian SW species but you'll need to brush up on your Portuguese or get good with Google Translate.
:: JAMPA FISHING :: Pesca Esportiva ::
There is a specialist lure and fly fishing shop just across the main street from the
Centro metro station, in an underground precinct. I can't remember the name, something like
Kings Sport perhaps? Run by a Japanese Brazilian who I went fishing with. I think it's the best shop of it's kind for many miles around so if you need supplies that is where to head.
Let me know how you get on
