“…Artificial reproduction of cyprinids is possible mainly after hormonal stimulation (Kucharczyk et al 1997a(Kucharczyk et al , 2005Brzuska 2005;Szabo et al 2002;Linhart et al 2006;Krejszeff et al 2008Krejszeff et al , 2009Podhorec and Kouril 2009;Yaron et al 2009;). The application of different spawning agents and doses resulted in different ovulation rates and gametes' quality (Glogowski et al 1997(Glogowski et al , 1999Babiak et al 1998;Kucharczyk et al 2005Kucharczyk et al , 2007Cejko et al 2010), which was usually caused by different interactions on the fish organism.…”

The study encompasses three reproduction seasons. Tench spawners caught during the spawning season originated from carp ponds (domestic stock) and a lake (wild stock). Fish were reproduced under controlled conditions after hormonal stimulation with GnRHa-containing pellets combined with metoclopramide (Ovopel) or carp pituitary homogenate (CPH). As a result of hormonal stimulation, eggs were obtained from a larger number of females originating from the lake (71.7%) than those originating from the pond (58.3%), although no other statistical differences were found. A similar relationship was recorded for the spermatozoa motilities (range from 72 to 76%). The obtained results indicate that both investigated reservoirs are suitable for tench broodstock management due to the fact that synchronization of ovulation among different stocks is easy to achieve. For this purpose, among the tested spawning agents, Ovopel could be recommended as being slightly more effective.

“…The nase is a widespread but increasingly endangered riverine cyprinid inhabiting moderate to fast-flowing rivers of Central and Eastern Europe (Szabó et al 2002;Kottelat and Freyhof 2007). Adults undertake spawning migrations into smaller tributaries or to gravel bars with swift currents for up to several dozen kilometres (Keckeis et al 1996;Peň áz 1996).…”

Abstract:The dispersal of fish larvae in rivers might result from water movement but also from larval behaviour. Although potentially crucial for dispersion, knowledge of the role of behaviour is still fragmentary. This study intends to contribute to the question of how riverine fish larvae drift or move. All dispersal-relevant movement patterns of larvae of a characteristic rheophilic species were analyzed based on the parameters (i) swimming activity, (ii) direction of movement, and (iii) the orientation towards the current vector. Experiments were conducted in a novel flume mesocosm at three different flow scenarios covering the current velocity range of natural habitats. Mean current velocities in these scenarios were under, near, and over the "critical current velocity", above which fish larvae are not able to constantly hold their position in the water column. Three consecutive larval stages were tested to account for possible ontogenetic shifts in movement behaviour, both during the day and at night. Our results strongly suggest that the assumption of mainly passively drifting larvae has to be refused; in total, 92.6% of all observed movement events were characterized by swimming activity and directed orientation, whereas only 7.4% could be assigned to passive drift. During downstream movement, a significant portion of movement events (57.1%) was attributed to larvae that orientated in an upstream direction and performed active swimming movements.Résumé : La dispersion des larves de poisson dans les rivières peut être le résultat du mouvement de l'eau, mais également du comportement des larves. Les connaissances sur le rôle du comportement demeurent fragmentaires, malgré l'importance potentiellement cruciale de ce dernier pour la dispersion. L'étude s'intéresse à savoir comment les larves de poissons de rivière dérivent ou se déplacent. Tous les motifs de déplacement pertinents pour la dispersion des larves d'une espèce rhéophile caractéristique ont été analysés en fonction des paramètres suivants : (i) l'activité natatoire, (ii) la direction des déplacements et (iii) l'orientation par rapport au vecteur de courant. Des expériences ont été menées dans un mésocosme en canal novateur pour trois scénarios d'écoulement différents couvrant la fourchette de vitesses du courant dans les habitats naturels. Les vitesses moyennes du courant dans ces scénarios étaient inférieures, semblables ou supérieures à la « vitesse critique du courant » au-delà de laquelle les larves de poisson ne peuvent maintenir constamment leur position dans la colonne d'eau. Trois étapes larvaires consécutives ont été étudiées pour tenir compte de possibles changements ontogéniques du comportement de déplacement, tant durant le jour que la nuit. Nos résultats donnent fortement à penser que l'hypothèse des larves dérivant principalement de manière passive doit être rejetée; au total, 92,6 % de tous les évènements de déplacement observés étaient caractérisés par une activité natatoire et une orientation dirigée, alors que seuls 7,4 % de ces...

“…(CPE) carp or bream pituitary (BPH), as well as natural gonadotropin-releasing hormone (sGnRH, mGnRH) and analogues (sGnRHa, mGnRHa), have proven to be effective tools when applied in aquaculture to induce ovulation and stimulate spermation in fish (Drori et al 1994, Brzuska 1999, Szabó et al 2002, Szabó 2003). The literature, as well as the authors' own observations, indicate that in cyprinid fishes the volume of milt and the quantity of spermatozoa obtained are influenced by the length of time after hormonal stimulation (Saad and Billard 1987, Caille et al 2006, Cejko et al 2010.…”
