Traits detail

Egg (100.0%)

Trait id	Trait	Primary data	Secondary Data	References
1	Oocyte diameter	3.07-0.14 mm	1.6 mm	Lenhardt et al, 2004
2	Egg size after water-hardening	6.5 ± 0.3 mm	6.5 mm	Lenhardt et al, 2004
3	Egg Buoyancy	No "The eggs became sticky upon activation, and they were quickly dispersed to form a single layer across the bottom of the hatching tray"	Demersal	Omoto et al, 2005
4	Egg adhesiveness	Yes "After eliminating egg adhesiveness (WILLIOT et al., 1991), eggs were placed in small incubators"	Adhesive	Gisbert and Williot, 2002
4	Egg adhesiveness	Yes "fertilized sturgeon eggs become sticky within a few minutes after coming in contact with water"	Adhesive	Linhart et al, 2016
5	Incubation time	5.0	5.0 days	Пономарева E. H. et al, 2017
6	Temperature for incubation	14.5-18.2 °C	16.35 °C	Пономарева E. H. et al, 2017
6	Temperature for incubation	15°C (sperm incubation) "After irradiation, 20 ml of 15 °C water from the incubation system was added to the irradiated sperm suspension"	15.0 °C	Fopp-Bayat et al, 2007
6	Temperature for incubation	7-15°C; 10h "We found that sterlet eggs do not need to be fertilized immediately after collection. Reasonably good quality was retained for several hours if temperature conditions are fairly cool and stable. Eggs retained good quality when stored at 7°C and 11°C for up to 10 h with 54.1 ± 2.9 to 69.9 ± 7.9% hatching success, but egg quality was significantly reduced after 5‐h storage at 19°C (p < 0.01) and 7.5‐h storage at 15°C (p < 0.05) compared to cooler temperatures. Uniform temperatures between 7°C and 11°C can be considered as appropriate for storage of eggs in ovarian fluid for up to 10 h"	54.1 °C	Linhart et al, 2016
7	Degree-days for incubation	16°C/5-6 days (eggs incubation) "5‐ to 6‐day post‐fertilization; water temperature during incubation was 16°C"	5.5 °C * day	Linhart et al, 2016

Larvae (100.0%)

Trait id	Trait	Primary Data	Secondary Data	References
8	Initial larval size	inital larval length 6.78±0.22 mm	6.78 mm	Lundova et al, 2018
8	Initial larval size	9.0 mm "The embryos hatched when reaching a mean total length (TL) of 9.0 mm."	9.0 mm	Rybnikár et al, 2011
9	Larvae behaviour	Benthic "sterlet's prolarvaes passes to a bottom mode of life"	Demersal	Kalmykov et al, 2010
10	Reaction to light	Photoperiod of 12L: 12D	Photopositive	Laczynska et al, 2017
10	Reaction to light	Light (color and photoperiod) influences egg quality during the final stage of A. ruthenus reproduction	Photopositive	Azarin et al, 2014
11	Temperature during larval development	Annual average temperature=18°C (7-32°C)	19.5 °C	Rzemieniecki et al, 2004
11	Temperature during larval development	5-25°C "25 ± 0.5°C (acutely high temperature) or 5 ± 0.5°C (acutely low temperature) for testing"	25.0 °C	Mandal et al, 2016
12	Sibling intracohort cannibalism	Present "A significantly higher cannibalism rate p<0.05) was observed in the RP1 group as compared to N2, O1,and O2"	Present	Lundova et al, 2018
13	Full yolk-sac resorption	7 dph "Gastric glands became visible on the 7 dph. The primary intestine developed into the spiral intestine. At the moment of onset of exogenous feeding the yolk material was completely exhausted"	7.0 °C * day	Wegner et al, 2009
13	Full yolk-sac resorption	7 dph at 18°C "The experimental rearing was initiated from 7 dph (after resorption of yolk sac) and continued until 38 dph in a recirculating aquaculture system (RAS). Water temperature was maintained at 18°"	7.0 °C * day	Laczynska et al, 2017
