“…Ovulation was observed even in the control group in 30% of females. This was proof of an excellent reproductive protocol and the appropriate stimulation with environmental conditions (mainly the temperature of water) as well of the effect of domestication on the outcome of the species reproduction Teletchea and Fontaine, 2014). Stimulation with environmental conditions (temperature, photoperiod) in cyprinids, even those bred by humans for centuries, does not induce maturation, especially in females (Brzuska, 2005(Brzuska, , 2006Kucharczyk et al, 2008;Targońska and Kucharczyk, 2011).…”

Artificial reproduction of common barbel (Barbus barbus) under controlled conditions usually did not exceed 10% of ovulation success. The aim of the study was to optimise the process of artificial reproduction of the barbel (cultured generation F4) with thermal and hormonal stimulation The first experiment examined the effect of stimulation with thermal conditions on the ovulation and the embryos survival rates. After the optimum conditions of thermal stimulation in barbel reproduction were determined, another experiment was conducted which examined how the effectiveness of reproduction is affected by four selected hormonal preparations (CPH, hCG, Ovaprim and Ovopel). Thermal stimulation for 58 days was found to be the most effective (748 degree-days). The second experiment examined the synergistic effects of different hormonal preparations under the optimal thermal conditions as, determined in the first experiment. Among the hormones evaluated as part of this study, CPH and Ovaprim were yielded the best results as compared to control. The use of the preparations resulted in the percentage of ovulations of 90-100% and the embryo survival rate at the hatching stage was about 90%. The study concludes that thermal stimuli and hormonal applications have a synergistic effect on artificial reproduction in B, barbus.

“…Farmed salm on have now been selectively bred over more than eight generations for a number of traits (growth rate, resistance to disease, age at sexual ma turity, feed conversion efficiency, fillet yield, flesh quality and colour) and represent one of the most genetically improved stocks within aqua culture (Asche and Bjørndal, 2011;Telechea and Fontaine, 2014).…”

Trends during development of Scottish salmon farming: An example of sustainable intensification?

et al. 2016

Commercial farming of Atlantic salmon in Scotland started in 1969 and has since expanded to produce N 179,000 t year −1 . A government department has published annual statistics and information on the seawater and freshwater sub-sectors of the Scottish salmon farming industry since 1979, and this review collates and dis cusses metrics covering aspects of production, farm sites and systems, fish performance, socio-economics and en vironmental pressures. Trends illustrated in this case study of aquaculture development include: initial increases in numbers of farms and companies, followed by decreases due to industry consolidation; increases in average farm size, and productivity of systems and employees; increases in survival, size at age and productivity of fish (yield per smolt, ova per broodstock); reduced dependence on wild stocks for ova. This case study also illustrates the importance of disease management, control of biological processes to overcome natural seasonality (i.e. pro duction of out-of-season smolt), and the international nature of aquaculture. Improvements in fish survival, growth and productivity are attributed to progress in vaccination and health management (including fallowing), husbandry, system design, feed formulation and provision, and introduction of technology and mechanisation. Salmon farming is discussed in relation to the challenging strategy of "sustainable intensification". Improved growth and survival over a period of increasing rearing unit size, farm size and output and decreasing relative staff input counters the common assumption that intensification compromises animal welfare. The value of cap turing time series data on industry wide metrics is illustrated as it enables identification of trends, underperformance and bench-marking, as well as assessment of resource use efficiency, environmental pres sures, and ultimately sustainability. Statement of relevance: This review is an original collation of a comprehensive set of time series of official statistics on an entire, discrete and regionally important sector of commercial aquaculture.Crown

“…The rainbow trout (Oncorhynchus mykiss), which is a salmonid originating from the west coast of North America, was one of the first fish species to be domesticated and introduced globally: today it is present in more than 90 countries [60,61]. In France, it was first introduced in the beginning of 1880 for angling [41].…”

Introduction of alien species constitutes worldwide one of the major threats to biodiversity, particularly in freshwater ecosystems. In France, the number of alien aquatic plant and animal species has increased exponentially over time in freshwater ecosystems and shows no sign of decreasing. For fish only, more than 40 alien species have been either voluntary or involuntary introduced in the past decades. About two-thirds are still present today and at least 26 are naturalized. As in many European countries, the fish introduction history in France switched from voluntary introduction in the nineteenth century (aquaculture, sport fishing, and management of ecosystems) to unintentional but humanaided introductions (aquarium trade and global ship transport). The negative impacts of alien species on native species and ecosystems are most often unknown in France and needs further studies to develop a functional policy on alien species introductions and the protection of aquatic ecosystems integrity. The information gathered allow discussing the possible reasons explaining whether an alien species is able or not to establish sustainable populations in France and thereafter became invasive, such as gobies recently arrived.
