“…Compared with other Perciformes fish, the results of our study were higher than the 4.47% in Micale et al (1996) for Diplodus puntazzo , 0.06%– 1.86% in Papadaki et al (2008), and 1.14% in Hernandez et al (2003). However, the results in this study were lower than the 8.21% of Perca fluviatilis (Abdulfatah et al, 2013), 10.8% of mandarin fish (Lee et al., 2012), 12.85% of dragonet (Baeck & Huh, 2004), and 7.50% of spotted sea bass (Kim et al, 2001). These differences may have resulted from the GSI being affected by differences in the age and size of mother fish caught in nature.…”

Effects of Size and Degree of Abdomen Inflation of the Mother Fish on Ovulation Induction of Red Spotted Grouper, Epinephelus akaara

We determined the morphologic characteristics (body weight and degree of abdomen inflation) of the red spotted grouper, Epinephelus akaara, mother fish producing healthy eggs. Experimental fish were chosen from fish reared in a sea cage. The fish were divided into four size groups by body weight: 400~600, 600~800, 800~1,000, and 1,000~1,200 g and four stages (Ⅰ~Ⅳ) of the degree of abdomen inflation. After hormone treatment, we observed the amount of ovulation-induced eggs, and rates of buoyancy, fertilization, embryonic survival, and hatching. As a result, mother fish with a body weight of 600 g or more spawned, and the fertilization rate, embryonic survival rate, and hatching rate were high in the 800~1,000 g range, thus showing effective ovulation induction. As a result of dividing the degree of abdomen inflation based on the anal fin of the mother fish into I-IV stages and determining hormone treatment time, the GSI was 0.9 ± 0.2% at stage I, 2.3 ± 0.2% at stage II, 5.6 ± 0.2% at stage III, and 7.9 ± 0.9% at stage IV. The flotation rate and hatching rate were highest at stage III, and the fertilization rate and embryonic survival rate were highest at stage IV. Therefore, in terms of egg quality, the amount of eggs collected per mother fish, maturation, and histology were different depending on the degree of abdomen inflation. At stage III, where the abdomen inflation degree of the mother fish was based on the basal part of the dorsal fin relative to the height of the anal fin was 1, the egg quality was highest.

“…Field and laboratory studies have shown that the initiation of reproduction in Yellow Perch and in the closely related Eurasian Perch Perca fluviatilis is influenced by both the rate of water temperature warming and photoperiod change, with temperature being important in determining the initiation and duration of spawning (Thorpe 1977;Kayes and Calbert 1979;Dabrowski et al 1996;Ciereszko et al 1997;Thackeray et al 2013), so shifts in timing to ensure suitable water temperatures (e.g., for egg hatching and fry survival) are not surprising. Interestingly, ovarian development appears to be tuned to photoperiod more than water temperature (Ciereszko et al 1997;Abdulfatah et al 2011Abdulfatah et al , 2013), suggesting potential constraints on plasticity in spawning responses to earlier warming.…”

Trends in the Reproductive Phenology of two Great Lakes Fishes

et al. 2015

To assess potential effects of climate change on Great Lakes fish populations, we evaluated trends in the reproductive phenology of Yellow Perch Perca flavescens (spring spawner) and Lake Trout Salvelinus namaycush (autumn spawner). For Yellow Perch in Lake Michigan, the estimated reproductive midpoint date (50% of mature females ripe or spent, 50% not yet spawned) took place 6.2 d/decade earlier in the spring near Milwaukee from 1988 to 2012 and 1.8 d/decade earlier in Green Bay from 1980 to 2012. At both locations water temperatures at the spawning sites on the midpoint date showed no trends, but mean water temperatures during the spring at the spawning site and midlake increased over the study period. This suggests that Yellow Perch spawning areas were warming sooner in the spring and that Yellow Perch were spawning earlier to maintain a consistent spawning temperature. Lake Trout phenological patterns were more complex. For Lake Trout in Lake Michigan near Milwaukee, there was a marginally significant trend for spawning to take place 2.1 d/decade later in the autumn from 1983 to 2006. However, water temperatures at the spawning site at the midpoint date did not change and autumn temperatures at the site and at midlake did not show a warming trend. For Lake Trout in Lake Superior near the Apostle Islands, the midpoint date did not change from 1988 to 2012. Water temperatures at the spawning site on the midpoint date and during the autumn also showed no trends, but midlake summer and autumn water temperatures increased significantly. Overall, Yellow Perch in Lake Michigan have shifted reproductive timing in a manner consistent with a warming climate, but the relationship of climate change to reproductive phenology remains unclear for Lake Trout in Lake Michigan and Lake Superior.The earth's climate is warming, resulting in major changes in the thermal conditions of many lakes (Magnuson et al. 2000;Schneider and Hook 2010). Over the last century, the Laurentian Great Lakes have experienced well-documented trends towards less ice and shorter winters (Assel and Robertson 1995;Assel et al. 2003), warmer summer temperatures

“…Temperature is often a controlling factor in fish gametogenesis (Wieland et al 2000;Wang et al 2010;Abdulfatah et al 2013). For teleosts inhabiting temperate zones, temperature can have a primary role in final gonad maturation and gamete release (Anguis and Cañavate 2005;Wang et al 2010).…”

Temperature and Maternal Age Effects on Burbot Reproduction

River regulation alters the thermal regime of many freshwater ecosystems, and impoundments are known to negatively impact the recruitment of fluvial Burbot Lota lota populations. Some conservation programs in North America and Eurasia have begun to incorporate stocking of hatchery Burbot to mitigate extirpation risks. Anthropogenic modification of river temperatures and population structure has unknown implications for Burbot reproduction. This study evaluated the effects of elevated water temperatures and different maternal ages on spawning and embryo development of hatchery Burbot. Juveniles stocked downstream of a hydroelectric dam were found to naturally mature in a warmer postdam regime. The river‐adapted hatchery adults volitionally spawned in a broodstock facility at 2, 4, and 6°C. The spawning period spanned 18 d at 2°C but was shortened to 6−7 d at 4°C and 6°C. Survival of embryos to the eyed stage was 86.7, 47.9, and 0.1% at incubation temperatures of 2, 4, and 6°C, respectively. Embryo deformity increased dramatically between 4°C and 6°C. Young (age‐3) and old (age‐7 and older) females spawned 4−12 d later than 5‐ and 6‐year‐old females. Age‐3 females spawned smaller eggs, but no relationship was found between maternal age and embryo vital rates. It was concluded that juvenile stocking supplemented the abundance of reproductive adults in the highly altered ecosystem of the lower Kootenai River. Spawning temperatures above 4°C potentially underlie Burbot recruitment bottlenecks in systems affected by impoundments, climate warming, or other barriers to coldwater spawning habitat. Contraction of the spawning period by warmer temperatures, a truncated population age structure, or both could synchronize spawning to coincide with suboptimal conditions for normal embryo development.
