Ueyanagi S Spawning of the albacore in the Western Pacific. Yet within the spawning time interval, the results of our study showed a small-scale pattern of variability. This latter assumption is more consistent with the results obtained from other groups monitored in this study and with results from studies based on archival data discussed further in the next section. Schultz ET The effect of birth date on fitness of female dwarf perch, Micrometrus minimus Perciformes: Embiotocidae. The scientific effort dedicated to this species is remarkable, from its physiology [2][3]migratory patterns [4] — [8]growth [9]feeding ecology [10] — [12] and reproductive biology [13] — [16]among others. The specific objectives were: to determine the onset of spawning, to identify the peak spawning period, to determine the spawning duration, to analyse the variability of the spawning time, to analyse the natural reproductive capability of individuals held in captivity from 1 to 4 years when exposed to the same environmental conditions as wild spawners, and lastly to study the variability of the egg hatching time with on-site sea water temperature.

    Annual reproductive cycles with a well-defined periodicity are considered likely to be entrained to day length, as this is recognized to be the most reliable environmental signal of time [50]. The transport of tuna groups under monitoring was done with the previous authorization from the Spanish Directorate-General for Fisheries.

    As in previous years, the temporal pattern showed two separate spawning pulses in June and a smaller and less clear one in July.

    Spawning started on May 22 nd with an SST of

    Pike are the first fish to spawn each year and feed much more aggressively as females fill out their Pike feed during the day, so anglers don't have to rise early or stay late to fish them. They show breaklines, some cribs/structure, shallow water areas and potential pike habitat.

Transport cages cannot be considered to present either pure captivity conditions like those specific to tuna farms, or wild natural conditions, as the fish are caged for transport and transfer to the farming facilities, but they are unique platforms for direct observation of spawning.
