Artificial spawning of common tench Tinca tinca (Linnaeus, 1758), obtained from wild and domestic stocks

Abstract

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.

Method of evaluation of wild common tench,Tinca tinca(L.), female suitability for artificial reproduction during the spawning season

“…The common tench, Tinca tinca (L.), is one of the freshwater cyprinid species that has had a huge impact on freshwater aquaculture (Wang et al, 2006;Celada et al, 2009;Kujawa et al, 2011). In recent years, the tench has become very important for both lake exploitation (Mamcarz and Skrzypczak, 2006) and pond aquaculture (Celada et al, 2009).…”

“…This has led to the rapid development of new techniques regarding different aspects of tench artificial reproduction (e.g., Rodina et al, 2007;Kouril et al, 2008) and the rearing of larvae and juveniles under controlled conditions (e.g., Wolnicki et al, 2006;Celada et al, 2009;Mamcarz et al, 2011). In most cases, the studies were carried out using cultured stocks of common tench (e.g., Svoboda et al, 2001;Rodrigez et al, 2004;Rodina et al, 2007;Kujawa et al, 2011) and they are in contrast with the published data concerning the different aspects of wild fish reproduction (Pimpicka et al, 1990;Alas and Solak, 2004;Benzer and Yilmaz, 2007;Kucharczyk et al, 2007).…”

Effect of live and dry food on rearing of tench (Tinca tincaL.) larvae under controlled conditions

“…Therefore, in recent years many scientific research programs have been dedicated to intensification of production. It concerns especially controlled reproduction , Kujawa et al 2010, sperm cryopreservation (Babiak et al, 1998;Cejko et al, 2010), gamete management , incubation conditions and initial rearing of larvae under controlled conditions (i.e. Kucharczyk et al, 1997;Kujawa et al, 2009;Wolnicki et al, 2003;Wolnicki et al, 2006;Mamcarz et al, 2006).…”

Influence of age of wild ideLeuciscus idus(L.) female on spawning effectiveness under controlled conditions

“…Latency time after hormonal stimulation was related to inter-populational differences (Kujawa et al, 2011), degree of domestication ) and type or dose of hormonal treatment Targoń ska et al, 2010). Differences in latency resulting from the size and age of females were reported for Eurasian perch, Perca fluviatilis L., where ovulation in older (bigger) fish took place later than in younger ones (Kucharczyk et al, 2001).…”
