“…However, given the high variability of kit procedures, reagents, and results in this experiment, commercial ELISA kits should be utilized for qualitative, not quantitative, determination of cortisol in fish within a single study, and should be fully validated in each laboratory for each species before an ELISA kit is used for research. Due to the current lack of validation procedures being conducted to ensure the accuracy of cortisol results (Biswas et al 2006;Wang et al 2006;Welker et al 2007), publication of validation results within manuscripts would allow more information to be transferred to the scientific community as well as improve the validity of the research being presented. The increased ability of fisheries researchers to use an ELISA without the problems of RIA would be a justification for use of ELISA cortisol analysis.…”

“…Barry et al (1993) did not compare cortisol results from the ELISA and RIA methods. Many aquaculture and fisheries publications report few if any validation efforts or suitability of the cortisol ELISA for the species being tested (Biswas et al 2006;Wang et al 2006;Welker et al 2007). Validation of an ELISA kit for the determination of cortisol is necessary as kit procedures and reagents vary.…”

Measurement of cortisol response is an important tool to asses stress in fisheries research. Radioimmunoassay (RIA) is a common method for the measure of cortisol in fish. Use of enzyme-linked immunosorbent assays (ELISA) to detect cortisol would eliminate health hazards, costs of handling radioisotopes, and the short stability time associated with RIA. Enzyme-linked immunosorbent assays have been used for the determination of cortisol in several fish species. However, the ELISA method of cortisol determination in fish lacks proper validation testing. We conducted validation procedures for multiple commercial cortisol ELISA kits and compared the results to RIA. The assays were tested for four species: (1) channel catfish Ictalurus punctatus, (2) largemouth bass Micropterus salmoides, (3) red pacu Piaractus brachypomus, and (4) golden shiners Notemigonus crysoleucas. We evaluated the ELISA methods against RIA, and determined that at least one kit is suitable (accuracy: mean recovery of spiked samples, 102.8%; reproducibility: interassay coefficient of variation < 10.5% for all species; precision: intra-assay coefficient of variation < 16.8% for all species; linearity: R (2) > 0.96 for all species) for the measurement of cortisol response in fish and comparative determination of stress. All of the ELISA assay results varied by more than 10% from the cortisol concentrations detected by the RIA. The high variability of the kit results indicates that commercial ELISA kits could be utilized for qualitative determination of cortisol in fish, but should be fully validated in each laboratory for each species before being used for research.

“…In this sense, decreases in the temperature range and timing of the photophase are the two main inductive cues for the European perch (Perca fluviatilis Linnaeus) reproduction (Wang et al 2006). Clark et al (2005) stated that water temperature plays a prominent role in the initiation, maintenance, and termination of the reproductive cycle in striped bass (Morone saxatilis Walbaum).Also, gonadal maturation in Senegal sole can be stimulated by lowering the water temperature during early winter (García-López et al 2009).…”

In this work, the wedge sole (Dicologoglossa cuneata) spawning under a natural thermocycle has been studied. The spawning parameters were similar to those of other flatfish in captivity, the relative fecundity being very high (1.7 ± 0.1 9 10 6 eggs kg female -1 per spawning season). The percentage of floating eggs decreased with time and was directly related to egg diameter, daily relative fecundity and fertilization rate. Nevertheless, the hatching rate variations were not correlated to any other spawning parameter. The temperature range during the spawning season was very wide (11-21°C) though the largest spawns occurred between 12 and 16°C. The natural temperature cycle influenced wedge sole egg production, the winter temperature minimum indicating the onset of spawning, but the variations in the reproductive season did not appear to affect the daily egg production. Future research should focus on the photoperiod and its interaction with temperature as key factor for spawning.

“…It may also be important in other fish families (percids, moronids) as evidenced by the effect of temperature decrease on the initiation of gonadogenesis and Aquaculture 376-379 (2013) [90][91][92][93][94][95][96] oogenesis (Clark et al, 2005;Migaud et al, 2002;Prat et al, 1999;Wang et al, 2010). In particular, some spring spawners need specific thermal conditions for the onset of reproductive cycle such as in sea bass (Moretti et al, 1999) and in Eurasian perch in which the initial decrease of temperature amplitude was found to influence the initiation of gonadogenesis (Wang et al, 2006).…”
