Stanley's Sabalo of South America

Postby rwwalleye » Tue Apr 08, 2014 3:11 am

Hi Everyone,
Well here is another page of information on another fish (the Sabalo) that Stanley is creating for his South America outing. It's beautiful country and an area with an enormous number of species of fish. Here's the info and I hope you enjoy the reading. Found a lot of interesting history on this fish.
Sabalo is a Central and South American species of ray-finned fish that inhabits the basin of the Parana River and the Paraquay River in the Argentine Mesopatamia and Paraguay, the Pilcomayo River in Bolivia, the Paraiba do Sul River in Brazil and the River San Juan in Nicaragua. In Spanish its common name is Sabalo; in Brazil it recieves the name Curimbata, curimba, corimbata,or grumata. In the U.S. it is also known by the technical term Tarpon prochilodus. There are many other species of fish with the common name sabalo, P. lineatus is therefore distinquished sometimes as sabalo jeton (bigmouth) or chupabarro (mudsucker).
The Sabalo has a maximum length of 50 - 60 cm (20 - 24 inches) and weighs up to 6 kg (13.5 pounds). Its body is tall and compressed, greenish - gray (lighter in the belly), with yellowish - green fins. It's mouth is circular and projects towards the front. It has two series of small teeth.
The Sabalo prefers deep waters and it sucks and eats organic mud, for which it's mouth is especially adapted. It migrates in large banks (schools), looking for warm waters during the spring in order to lay eggs.
The Sabalo is considered the key species of the Parana River, since it forms the base of the food chain that ends with larger fish like the Surubi. Regulations in place in Santa Fe and Entre Rios, Argentina, have proven ineffective to preserve the species, which is being severely exploited, both for internal consumption and for export. Experts estimate that capturing 20,000 tons of Sabalo per year is upper limit of sustainability. Exports of about 13,000 tons in 1998, grew to 34,000 tons in 2004, after the depreciation of the Argentine peso caused by the economic crisis tripled its local value.
As the fish populations dwindles, fisherman who depend on their captures for their livelihoods are keeping smaller specimens, often not mature enough to have time to reproduce.
Widespread disregard of prescribed net sizes and the presence of illegal processing plants, which the local governments do not control, have compelled environmental groups to protest. The issue turned into a jurisdiction conflict when Santa Fe tightened the regulations in 2005, forbidding the capture of Sabalo under 42 cm long, while Entre Rios kept the limit looser at 40 cm. On July 13, about 400 fisherman blocked the Rosario access to the Rosario-Victoria Bridge that joins the 2 provinces. On August 1, After Entre Rios matched it's regulations with those of Santa Fe 300 fisherman and freezing plant workers from Victoria did the same. They were pressured, acording to certain claims, the the threat of unemployment if their plants cannot fill their export quotas.
In October 2006, largely to facilitate the reproduction of Sabalo, the legislation branch of Sante Fe attempted to pass a temporary ban on commercial fishing in the Parana. This ban was vetoed by the executive branch, as it had no counterpart in the neighboring Entre Rios. On December 21, 2006, the national government banned exports of the fish of the Parana River for 8 months starting on January 1, 2007.
