Trp and endocrine regulatory scheme on oocyte growth and maturation in fish (adapted from Babin et al., 2007; Finn and Cerdà, 2024; Pavlov and Emel’yanova, 2016). Abbreviations: GnRH, gonadotropin-releasing hormone; LH, Luteinizing hormone; FSH, follicle-stimulating hormone.
Mel Levels in catfish broodstock after treatment with Trp. Error bars represent the standard deviation (SD) of the mean. The superscript letters above the error bar and observation time show a significant difference between the means using the DMRT multiple range test at p< 0.05. Dashed lines separate the DMRT test results for observation times. If there is no significant difference due to the observation time, the difference in hormone levels at that time will use superscript letters above the error bars with the same letter range.
