11/04/2011В В· In females, changes in the age of maturation were encompassed by variations in growth, whereas in males there was a temperature-related shift in the age at maturation that was unrelated to growth. Our experiment demonstrates that temperature can affect maturation directly, and not only through temperature-induced changes in growth. Therefore Here we report the successful maturation of female American eels. Maturation occurred within 13 weeks and ovulation was induced with a single injection of 17О±,20ОІ-dihydroxy-4-pregnen-3-one (DHP). Following in vitro fertilization, embryogenesis through hatching was observed and larvae were maintained for up to 6 days. We show that a crucial

A period of oocyte growth is followed by a process called oocyte maturation (the resumption of meiosis) which occurs prior to ovulation and is a prerequisite for successful fertilization. Our studies using fish models have revealed that oocyte maturation is a three-step induction process involving 06/08/2018В В· VrtГ­lek et al. demonstrate that wild Nothobrachius furzeri, an African annual fish, attains maturity in just 14 days, supporting viable populations in pools that risk desiccation within 3 weeks. Surviving as diapausing eggs for most of the year, this species combines a vertebrate body plan with an invertebrate solution to unpredictable conditions.

In P. celidotus, maturation and spawning of first-year females (0+) was delayed with respect to older (≥1+yr) females. Within the 0+ age class, the minimum size of maturation declined as the spawning season proceeded. However, in all females of T. varium, … Using mixed populations of GH transgenic and non‐transgenic Atlantic salmon siblings, we test the effect of growth on precocious maturation. If growth has a causative role in parr maturation, then GH transgenesis should increase the likelihood of early male maturation over the first and second years of life. However, if energy accumulation

Regulation of oocyte maturation in fish.. The fish were caught between early September and mid‐October (i.e. at the end of the growing season, but before the spawning period) between 1991 and 1996. Data collected from 11 sites were used in this analysis, although not all sites were sampled in all years (mean number of sites sampled per year = 7·5)., Memory of Faculty of Fisheries, Kagoshima University 32, 115-120.

It has been well documented in adult cuttlefish, which use polarization sensitivity in a large range of tasks such as communication, orientation and predation. Because cuttlefish do not benefit from parental care, their visual system (including the ability to

Using a fine-scale genetic map, Schumer et al. examined local ancestry in replicate natural hybrid populations of swordtail fish.
