Bottom of DR1 tank, the sides of the module are fitted with glass panels which allow natural light from a window to enter the tank, and the observer to view the behaviour of the broodstock. This device ensures easy viewing and checking of the broodstock, facilitates management of feeding and allows effective monitoring of reproduction. in Reproduction of Zingel asper (Linnaeus, 1758) in controlled conditions: an assessment of the experiences realized since 2005 at the Besançon Natural History Museum

Top view of DR1/DR2 double riffle, each section contains a spawning ground made up of eight gravel-filled trays, a rest area. The "double riffle" was designed to accommodate two groups from 25 to 50 specimens of broodstock in strictly identical conditions. The spawning grounds are equipped with waterproof, motion-sensing cameras with infrared night vision, connected to a 1000 Gb recorder. The diurnal and nocturnal activities of the two groups can therefore be simultaneously recorded over a long period. in Reproduction of Zingel asper (Linnaeus, 1758) in controlled conditions: an assessment of the experiences realized since 2005 at the Besançon Natural History Museum

Operating diagram of DR1/DR2 double riffle; it consists of two independent sections (DR1 and DR2), each containing 630 litres of water and measuring 2.5 x 0.6 m. Each section contains a filtration system separate from the fish, a cooling unit and an ultraviolet sterilizer. An 80 W UQL lamp completes the lighting of the module lit during the day. in Reproduction of Zingel asper (Linnaeus, 1758) in controlled conditions: an assessment of the experiences realized since 2005 at the Besançon Natural History Museum

Operating diagram of the incubator, two tiered modules contain six independent incubators. Three shallow hatching are (220 × 60 × 17 cm) stacked on top of each other to create a compact assembly in which each tier functions independently. Eighteen trays covered with eggs can be placed in each tier, allowing the simultaneous incubation of seven to nine lays. in Reproduction of Zingel asper (Linnaeus, 1758) in controlled conditions: an assessment of the experiences realized since 2005 at the Besançon Natural History Museum

Figure 8. – Egg production as a function of age. These results were obtained from the number of eggs laid throughout the breeding season divided by the number of females that laid. The same bloodstocks (born in captivity in 2008) were used for 9 years. The maximum production was obtained at 6 years. The number of females was 17 at the beginning and 2 at the end (Tab. II).

C: A low pressure from the abdomen towards the anus with the index finger allows the ova to be extracted. D: The yellow colour of the ova is a good indicator of their good quality. E: Water can only be added when everything is well mixed.
