5mg/mL) click here to a peak in autumn just before spawning (50mg/mL) [5]. In the once and twice spawners examined in this study, the peak of V was lower, at approximately 30mg/mL; however, the general pattern is consistent with that observed in previous data [5, 20]. Following the data reported by Maitra et al. [21] in the Mrigal carp (Cirrhinus mrigala), plasmatic levels of this lipophosphoprotein complex are expected to fall to undetectable basal levels after spawning. Moreover, it is worth noting that in this study, comparisons of the plasmatic levels of E2 and V between once and twice spawners reveal a chronological delay in which twice spawners displayed a compressed cycle due to two spawning events in the same year.

The present findings offer new contributions regarding the reproductive physiology of biannually spawning rainbow trout, further extending characterization of the different attributes of this trait, such as the reproductive performance [6�C10] and the underlying genetics [22]. We hope that this work provides more comprehensive knowledge of the oogenesis of twice spawner rainbow trout broodstocks, a strain that has potential to contribute to new high-fecundity broodstocks for farming.Conflict of InterestsThe authors have declared that no conflict of interests exist with the commercial entity mentioned in the paper.AcknowledgmentThis study was financed by Fondo Nacional de Investigaci��n Cient��fica y Tecnol��gica (FONDECYT) Project no. 1060623.
Weather is the key source of uncertainty affecting crop yield especially in the context of climate change [1�C3].

For example, Vergara et al. studied the potential impact of catastrophic weather on the crop insurance industry and found that 93% of crop loss was directly related to unfavorable weather [4]. Accurate modeling of multivariate weather distributions would allow farmers to make better decisions for reducing their exposure to weather risk or take advantage of favorable climatic relationships [5]. Among variables relevant to weather, rainfall and temperature are two GSK-3 important factors which have a large effect on crop yield [6�C9]. Typically, temperature affects the length of the growing season and rainfall affects plant production (leaf area and the photosynthetic efficiency) [10, 11].There is a lot of literature studying the effects of temperature and rainfall on crop yield. Erskine and El Ashkar quantified the effect of rainfall on lentil seed yield and found that rainfall accounted for 79.8% of the variance of seed yield [12]. Lobell et al.
