ABSTRACT The early life stages of fish represent a period high energy requirements due to profound changes that characterize the passage adulthood, crucial for fisheries recruitment. This study focuses on North Patagonian Frontal System (NPFS) guarantees successful larval development and fulfills three postulates Bakun's “fundamental triad” in regards nutrients, concentration food, retention eggs larvae inside favorable area. objective was evaluate nutritional condition Merluccius hubbsi...
The existing literature has classified Engraulis anchoita larvae as exclusively zooplanktophagous, with copepod eggs and nauplii their main prey. However, there is evidence that other plankton components have not been identified by intestinal content analysis may be a part of diet. objective this work was to explore trophic positions food sources E. analyzing stable nitrogen carbon isotopes (δ15N δ13C) respect (particulate organic material, calanoid copepods, chaetognaths) at fixed sampling...
It has been proposed that vertical movements of planktonic organisms coupled to a horizontally or vertically stratified circulation pattern could describe retention mechanism, with ecological advantages such as favoring recruitment success. The Patagonian stock the Argentine hake Merluccius hubbsi spawns mainly from January February in relation highly productive tidal frontal system. Although fish eggs and larvae previously hypothesized for this system, it not fully proven its mechanisms...
Abstract The aim of the present study is to provide first results on reproductive biology Mugil platanus, from Mar Chiquita coastal lagoon (Argentina). To address this topic, we employed mainly female gonads, at both microscopic and macroscopic levels. following stages oocyte development were observed: (A) oogonias, (B) primary growth oocyte, (C) cortical alveolus stage, (D) yolked oocytes, (E) atretic follicle. Also five seven gonad maturity macro microscopically stated. potential fecundity...
A comparative analysis on various aspects of the reproductive biology 7 Sciaenidae family species was done. In addition parameters needed for stock assessment models were provided. The research covered duration breeding season and estimation variables such as size at maturity, fecundity spawning frequency. When all considered together, some reproduction similar, regarding strategy; are batch spawners with indeterminate an extensive (approximately six months) except Pogonias cromis , which...

Abstract Uterine layer changes and their relationship with the reproductive cycle were analyzed for southern eagle ray Myliobatis goodei (Chondrichthyes: Myliobatidae), based on histological histometric studies. The specimens collected from bottom-trawl surveys conducted in coastal southwest Atlantic ecosystem between latitude 34 42°S. Oviduct samples removed fixed 10% buffered formalin until processing analysis. Both oviducts are developed mature females, but only left is functional. After...

Knowledge of environmental influence on reproductive dynamics in chondrichthyans is critical for effective management. The present study assessed the potential influences temperature and depth aggregations events narrownose smooth-hound shark (Mustelus schmitti), using an analysis criterion based co-occurrence different stages. Data were collected from 363 sample sites during six research surveys, covering area ~47744km2 along coast (38–42°S, <50m). Aggregations M. schmitti adults mostly...
Quantitative analysis of the melano‐macrophage centres in Micropogonius furnieri were made. The results obtained showed a stimulation mononuclear phagocytic system related to presence contaminants.
The reproductive biology of the king weakfish, Macrodon ancylodon , inhabiting estuarine waters Río de la Plata (Argentina–Uruguay), was studied using macroscopic and histological analysis gonads. samples were collected from commercial landings three research cruises carried out between 1999 2001. King weakfish is a multiple spawner with indeterminate annual fecundity. Spawning this species extends October to March two main peaks gonadal index in November March. Based on incidence females...
