“…Mullet is the gourmet food in restaurants throughout the cited area, and is a sought‐after species by sports fishermen from Buenos Aires Province. Several studies on M. platanus include food habits (Rocha Oliveira and Soares, 1996), the digestive system (Galvao et al., 1997), morphology of the gill arches (Fonseca Neto and Spach, 1999), taxonomy (Cousseau et al., 2005), and reproduction (Vieira and Scalabrin, 1991; Romagosa et al., 2000; Esper et al., 2001). Studies related to age and growth of this species, however, have not been published.…”

SummarySpecies of Mugilidae are an important economic resource supporting several small communities in Argentina and Brazil through fishing. The growth parameters of the von Bertalanffy model, age limit (t 0.95 ) and natural mortality (M) for the striped mullet (Mugil platanus) Gü nther, 1880, in the Mar Chiquita coastal lagoon (37°32¢S-57°19¢W) were estimated. These results constitute the first estimated values for the species as: L ¥ (cm) = 563.82; K (years )1 ) = 0.30; t 0 (years) = )0.057 (age groups 1-8); t 0.95 = 10.07 years and M = 0.30. Moreover, a hypothetical model is proposed for the life history of the adult stock of M. platanus from the Mar Chiquita coastal lagoon based on CPUE data, environmental parameters, ovarian maturity stages, gonadosomatic indexes, the allometric growth coefficient b and deposition of hyaline or opaque rings in the otholiths. Mugil platanus is therefore regarded as a species of moderate to rapid growth rate, with a relatively low longevity and a high natural mortality rate, compared to other species of Mugilidae.

Most water bodies in Brazil, and in the world, are contaminated by some types of pollutants, ranging from sewage to metal/chemicals, carcinogenic products, and biodegradable detergents. Despite the extensive knowledge on their effects on fish biology and especially on gill morphology, research that concerns their impacts on gill rakers and implications in parameters such as food consumption cannot be found in the literature. Gill rakers are vital because, together with gills, they are responsible for the defense and protection of the organism and for selecting appropriate food for survival. When detergents, which can act as toxic chemical agents, get in contact with the body of the fish, they can cause severe effects that must be understood. Therefore, our study investigated ultramorphological changes in gill rakers of Astyanax altiparanae (Lambeth) caused by the exposure to biodegradable detergents. Fish were exposed to a 1 mg/L dilution of a mixture of detergents and pure water from an artesian well for 5 months. Results revealed that the first month of exposure to detergent caused dilation of chemical receptors in taste buds and the rise of a large number of orifices for mucus release among pavement cells in gill rakers, although only a small amount of mucus was found in fish exposed both to pure water and the detergent dilution. After 5 months, there was an increase in the dilation of these chemoreceptors, excess mucus on gill rakers of detergent groups, and the emergence of microbridges between microridges in pavement cells.
