“…Populations of O. argentinensis are economically significant resources for local fisheries in southern Brazil, Uruguay and Argentina (De Buen, 1953; Chao et al ., 1985; Sampaio, 2006). As a shallow‐water pelagic fish, the species is captured in Brazil by artisanal fishing in the Laguna dos Patos, (Moresco, 2006) and is exploited in Argentina by recreational and artisanal fisheries in Buenos Aires Province (Llompart, 2011; Llompart et al ., 2012) as well as on the coast of Chubut Province, where this species represents the second most fished species after Odontesthes smitti (Lahille 1929) (M. A. López, unpubl. data).…”

This study assesses for the first time the relationship between annual cycles of different biological indices with growth patterns of a marine pejerrey Odontesthes argentinensis population near its southern-distribution boundary in North Patagonia. The reproductive period is between September and November evidenced by an increase in the gonado-somatic index with a peak in October corresponding to spawning. The reproductive cycle was also coupled with metabolic processes related to energy allocation as shown by changes in the hepato-somatic index and body condition. Total length (L(T) ) at maturity was 270 for females and 282 mm for males, whereas fecundity was estimated at mean ±s.d. = 9380 ± 1797 mature oocytes. Based on the marginal increment analysis, most of the scales showed a maximum value during summer, with a sharp decline thereafter during autumn and winter, indicating that scale rings are formed during the latter period and only once a year. Growth fitted by the von Bertalanffy model for both males and females did not show significant differences and showed a rapid growth during the first 2 years. The shorter reproductive period compared with that of the northern O. argentinensis populations inhabiting tropical and subtropical areas was interpreted as an adjustment to temperate environmental conditions. The larger maximum L(T) and L(T) at first maturity are in agreement with the counter-gradient hypothesis and could be related to the selective effects of low temperature and a shorter growing season. This latitude dependency argues strongly against the application of the same fishing regulations for different O. argentinensis populations as a whole and reinforces the need to assess basic biological features at a population scale to promote local sustainable fisheries management.

A total of 442 anglers in a coastal region of SE Brazil were interviewed to obtain information about recreational fishing. The anglers were mature individuals (mean age ≈43 years) with a high level of education. However, many did not have a fishing licence. Target fishes belonged to 47 species. Mean catch (Catch per unit effort ‐ CPUE) was 4.2 fish−1 day−1 or 488 g−1 angler−1 day−1. Total estimated catch in the study period was equivalent to 2% of commercial landings, indicating that recreational fishing has little impact on fish stocks. The anglers complained that fishing conditions had worsened because of environmental degradation. Catch‐and‐release was classified as a ‘good’ attitude despite reports of practices that caused suffering to fish. However, when asked about prohibition of catch‐and‐release, which is enforced in some countries, the anglers said they would not accept such a prohibition if proposed by Brazilian fishing authorities. As a general rule, issues related to animal welfare and animal rights are not discussed widely by society or by fishing authorities in Brazil. Suggestions for integrated management of coastal resources and for monitoring recreational fishing are presented.

“…; Llompart et al . ), official statistics do not include consistent catch, effort or socio‐economic information, particularly for recreational fishing tournaments. When data are not collected in a standardised manner, there is a high risk of any data collected being lost, hindering the understanding of the systems affected.…”
