Rearing juvenile tench (Tinca tinca L.) under controlled conditions using Artemia nauplii as supplement to a dry diet

Abstract

A 120-day experiment was performed with 4-month-old juvenile tench [initial mean weight: 0.31 g; total length (TL): 32 mm] to evaluate live Artemia nauplii as supplement to a dry diet for salmonids. All groups received the dry diet. Five treatments, differing in the amount of supplemented Artemia, were tested: without supplement, 450, 900, and 1,800 nauplii g -1 initial fish biomass, and nauplii in excess. Groups that received Artemia supplement had significantly higher survival (between 89.4 and 98.7%) compared to those that received dry diet alone (49.2%), while among them there was no significant difference. Juvenile tench fed the dry diet supplemented with Artemia in excess had a specific growth rate (1.98), weight (3.40 g), and TL (63.90 mm) significantly higher than those in the rest of the treatments. The latter three features were not significantly different under limited co-feeding (450, 900, and 1,800 nauplii g -1 biomass) averaging 1.26 specific growth rate, 1.40 g weight, and 48.50 mm TL. Tench fed the dry diet alone grew significantly less than the rest. Thus, the drawbacks of feeding juvenile tench with dry foods originally formulated for other fish species can be overcome by providing a supplement of Artemia nauplii.

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).…”

Effects of temperature on body chemical composition and incidence of deformities in juvenile tench, Tinca tinca (Actinopterygii: Cypriniformes: Cyprinidae), fed a commercial dry diet and/or natural food

“…Recently, the tendency of intensive aquaculture to produce fish of low biological quality, including those with body deformities, has become a problem of major importance (Witten et al 2009, Boglione et al 2013a, 2013b. In tench, an increasingly important aquaculture species, this problem is very common (Rennert et al 2003, Kamler et al 2006, Celada et al 2009, García et al 2010, González-Rodríguez et al 2014.…”

“…Tench, Tinca tinca (Linnaeus, 1758), a freshwater fish belonging to the family Cyprinidae, has a great potential for aquaculture Celada et al, 2009;García et al, 2013). Originally occurring in the waters of Europe and Siberia, today tench occurs in the inland waters of all continents (Freyhof and Kottelat, 2008).…”
