“…Similar observations were reported in other anemone species also (Overton et al, 2008;Melville and Griffiths, 1997;Madhu et al, 2006a) however, there were some variations in fanning and embryonic development periods related to anemone fish species. Mariscal (1970) reported the embryonic development rate of fertilized eggs were varied depending on ambient temperature and dissolved oxygen content of water in the tank.…”

“…Spawning and behavioural aspects of many Pomacentrid species have been well documented by previous researchers (Alva and Gomes, 1989;Wilkerson, 2001;Overton et al, 2008;Dhaneesh et al, 2009;Ajith Kumar and Balasubramanian, 2009;Swagat et al, 2012;Uthaya Siva et al, 2014). However, description of ova, embryonic development, larval rearing and production of juveniles are available only for a few Pomacentrids and are scarce in the case of species dwelling in Indian waters.…”

“…The present study resulted that fertilization, hatching and deformation rate of larvae were depends on several factors (feed quality, brooder health and environmental parameters) not only because of brooders. Although, the brooders were maintained in the backwater (with salinity variation) showed similar fecundity and spawning frequency to those kept in running seawater (Alva and Gomes, 1989;Wilkerson, 2001;Overton et al, 2008;Dhaneesh et al, 2009;Ajith Kumar and Balasubramanian, 2009;Swagat et al, 2012;Uthaya Siva et al, 2014).…”

Broodstock development, spawning, fertilization, embryonic development, fecundity, "hatching rate and deformation rates" of five species (Amphiprion ocellaris, A. percula, A. melanopus, A. clarkii and A. nigripes) of anemone fish were studied in captive condition. The egg diameter, parental care, fecundity rate, fertilization rate, hatching rate, deformation rates and size of eggs were quantified. In addition, the courtship behaviors and parental care of each broodstock were noted. The day wise embryonic developments from 1 st day to 8 th day were observed under microscope and major morphological and functional features of embryos were documented. The egg size ranged from 2.2 to 3.1 mm in length and width of 1.1 to 1.3 mm. The numbers of spawned eggs were varied between 405 to 810 numbers. Spawning was achieved in every 15 to 20 days of interval in summer and in monsoon it was increased ranging from 20 to 40 days. The clutch diameter ranged from 5.2 to 14. 3 cm in length and width of 4.8 to 11.5 cm.

“…As a result, glucose concentration at the end of stress treatment in E. moara was found to be at significantly low levels (P < 0.05). Continuous stress affects growth, survival and even reproduction of fish, as reported in other fishes (Overton et al, 2008). …”

“…Such stressors can induce physiological responses with adverse effects on growth, reproduction, immune response, and fillet quality (Overton et al, 2008). Therefore, understanding and monitoring the biological mechanisms underlying stress responses will facilitate alleviating their negative effects through selective breeding and changes in management practices, resulting in improved animal welfare and production efficiency (Yaashuwanth et al, 2014).…”

To evaluate effects of physical stress on physiological and non-specific immune parameters in Epinephelus moara, levels of cortisol, glucose, lactic acid in serum, as well as malondialdehyde (MDA), Alkaline phosphatase (AKP), acid phosphatase (ACP) and lysozyme (LZM) activities in liver were examined. Plasma cortisol levels increased significantly to peak levels at the first day in stressed individuals. Moreover, those levels were significantly higher with respect to control (P<0.05). Concentrations of glucose in serum has only a slight increase at the first day when subjected to stress (P>0.05). The levels of lactic acid, activity of ACP and AKP increased and significantly peaked during treatment; then, all of them dropped to the levels of control groups at the end of treatment. The concentration of LZM and MDA in liver had a significant increase and peaked during treatment; then it began to drop, and finally recovered to the level of control groups. The results indicate that E. moara presented significant physiological and immune responses when subjected to a repeated physical stressor. Also, cortisol and MDA changes could be used as bio-indicators for monitoring stress. The present study provides basic information for improved rearing and feeding protocols in this species.

During summer 2011, samples of sediment, macrophytes, and fish tissues from the shallow, slightly alkaline Lake Neusiedl, Austria, were evaluated for their total Hg content. This is the first report of Hg levels from this lake. Sediments displayed Hg contents between 0.025 and 0.113 μg g(-1) dw (dry weight), significantly correlating with the proportion of organic components pointing to a small anthropogenic impact on the lake's Hg content. Hg Levels in plants and fish were unexpectedly high: both investigated submerged plant species, Potamogeton pectinatus and Myriophyllum spicatum, showed mean values of 0.245 ± 0.152 and 0.298 ± 0.115 μg g(-1) dw, respectively. Biomagnification was evident when comparing muscle samples of the planktivorous fish species rudd Scardinus erythrophthalmus (n = 10, mean = 0.084 μg g(-1) ww (wet weight)) with the piscivorous perch Perca fluviatilis (n = 21, mean = 0.184 μg g(-1) ww) or pike-perch Sander lucioperca (n = 9, mean = 0.205 μg g(-1) ww). Significantly lower values were found in the muscle of the piscivorous pike Esox lucius (n = 25, mean = 0.135 μg g(-1) ww), pointing to a specific Hg metabolism of this fish, presumably under the particular physicochemical properties of the lake. Hg Concentrations in fish could pose a risk to piscivorous birds in this protected wetland system.
