Piedras Moras reservoir (32° 10'27" S and 64° 16' 29" W; 832 ha), integrates a series of artificial lakes belonging to the Rio Tercero basin (Córdoba, Argentina). During March 2009 an algal bloom occurred, coinciding with several animal species mortality, mainly wild birds. The goal this work was establish trophic status in relation that mortality. Variables were evaluated situ (temperature water transparency) samples taken order identify species, Chl-a concentration (spectrophotometry)...
In South America, the order Atheriniformes includes monophyletic genus Odontesthes with 20 species that inhabit freshwater, estuarine and coastal environments. Pejerrey argentinensis is widely distributed in areas of Atlantic Ocean known to foray into estuaries river systems, particularly conditions elevated salinity. However, our knowledge, a landlocked self-sustaining population has never been recorded. this study, we examined pejerrey Salada de Pedro Luro Lake (south-east Buenos Aires...
Argentina's central region includes an important area covered by shallow pampean lakes and dams. In these environments, fishing of pejerrey Odontesthes bonariensis Valenciennes, 1835 (Pisces, Atherinopsidae), the most fresh-water fish country, is a relevant social activity also considerable economic resource. The main diseases found in this species were studied from 1992 to 2003 provinces Córdoba, La Rioja Santa Fe (30º 35º S, 61º 67º W). Most cases registered high temperature months....
The pejerrey Odontesthes bonariensis is the most important freshwater fish of Argentina central region. present study was conducted to describe seasonal variation parasitism in O. from La Viña reservoir (31º 17'S, 65º 01'W), located province Córdoba, Argentina. Between years 1999 and 2002, 573 fishes were caught, their parasite infection relative weight (Wr) assesed. Three parasites found, Lernaea cyprinacea (Crustacea), Contracaecum spp. larvae (Nematoda) Cangatiella macdonaghi (Cestoda)....
Parasitic copepods of the family Lernaeidae are often found infesting freshwater fishes worldwide. They cause lernaeosis, a disease that can lead to serious pathogenic effects on their fish hosts. The most common lernaeid is Lernaea cyprinacea, which has been widely introduced through importation tropical fishes, e.g. cyprinids. In South America, it one parasites both in wild and farmed central region Argentina. silverside Odontesthes bonariensis important sport fisheries Argentina affected...
Abstract Nematode species of the genus Contracaecum Railliet & Henry, 1912 have been reported around world in many fish-eating birds and seals. Here, jorgei n. sp. is morphologically described using light scanning electron microscopy for adults fourth-stage larvae (L4) found bird Nannopterum brasilianus third-stage (L3) freshwater fish Hoplias argentinensis , both from province Córdoba, Argentina. Additionally, sequences cytochrome c oxidase subunit II were obtained these specimens...
El género Contracaecum pertenece a la familia Anisakidae, cual incluye parásitos de considerable importancia económica y médica. Las larvas están asociadas con una amplia variedad peces marinos agua dulce. Si bien, hay gran cantidad reportes que indican presencia anisákidos en diferentes partes del mundo, los estudios región central Argentina son escasos, pese las prevalencias observadas años recientes. Este estudio proporciona nuevos registros analiza aspectos ecológicos presentes ambientes...
Objective- The study aims to determine efficacy of propofol as an inmersion agent induce anesthesia in rainbow trout (Oncorhynchus mykiss). Design- Experimental study. Animals- 36 healthy Procedure- Trouts were sorted ramdomly two groups, 18 fish each one. Both groups anesthesized by bath, one them with 2,5 mg/l, the other at 5 mg/l concentration. During experiment, basal respiratory rate, partial and total equilibrium loss, time anesthesia, anaesthesia rate manipulation response recorded....
Several dams have been built in central and north Argentina. There are more than 20 reservoirs Córdoba province, with a total estimated surface area of around 15,000 ha. Although construction continues, some aspects about the richness, abundance diversity ichthyofauna many these environments unknown, which prevents adequate management fish resources. The goal this work was to evaluate specific richness La Viña reservoir (31° 47' S 65° 01' W, 1,050 ha, 846 m asl), one major Córdoba. Fifteen...
Hoplias argentinensis is a recently described species in the extreme south of Neotropical region. Despite its wide distribution, high trophic level, and relevance for sport fishing, detailed information about diet lacking. In this work, new insights on ecology H. from two Pampa shallow lakes Argentina are presented. For purpose, complementary characteristics were explored, particularly aspects selectivity, feeding strategy, breadth, individual specialization, as well patterns associated with...
