Hace
pocos días que la editorial Springer
Nature ha publicado un libro titulado
Reproduction in Aquatic Animals. From Basic Biology to Aquaculture Technology,
que he tenido ocasión de co-editar con nuestro colega Manabu Yoshida, de la
Universidad de Tokyo (Japón).
La
idea de escribir este libro surgió en el International
Symposium “AQUAGAMETE: Reproduction of
Aquatic Animals” que se incluyó en el 22nd
International Congress of Zoology and the 87th meeting of the Zoological
Society of Japan, que se celebró en Okinawa (Japón) en 2016.
A continuación
incluyo la referencia completa, el resumen del libro y los resúmenes de los dos
capítulos que Luz Pérez y yo mismo hemos escrito.
Gracias a todos
los colegas que han participado en la redacción del contenido del libro.

Even though
there are many animals in terrestrial habitats, there is great biodiversity to be
found in aquatic ecosystems. Furthermore, aquatic animals show various reproductive
systems: many animals perform external fertilization, others show internal
fertilization without mating, some are viviparous, etc. This means that the
reproduction systems of aquatic animals are highly diverse, and they are
excellent models for studying adaptive evolution and species-specificity of
fertilization. In addition, many aquatic animals such as fish, crustaceans, and
mollusks are important as fishery and aquaculture resources. Nevertheless,
their reproductive systems are also diverse, resulting in difficulties in
cultivation, especially in the production of juveniles. Thus, comprehensive
knowledge of the reproductive systems of various aquatic animals will help us
understand the systems of each animal, resulting in breakthroughs in the
research areas and aquaculture technologies. However, only a few books overviewed
the reproductive systems of aquatic animals from invertebrates to fishes since
many researchers focused their animals of interest. Therefore, our aim with
this book was to overview the various reproductive systems of aquatic animals.
The idea for
this book was initially conceived in the International Symposium on
“AQUAGAMETE: Reproduction of Aquatic Animals” held in the Joint Meeting of the
22nd International Congress of Zoology and the 87th meeting of the Zoological
Society of Japan, which was held from 14th to 19th November 2016 in Okinawa,
Japan. Three years have passed since the initial planning, and we have
developed the book ideation. In order to introduce up-to-date knowledge on the
reproduction systems of various aquatic animals from basic biology to
aquaculture technology, we invited up-and-coming researchers to contribute. This
book consists of 17 chapters and a foreword that details the history of spermatology
to be read before the main chapters. Finally, the book covers the reproductive
systems of both sperm and egg in cnidarians, annelids, arthropods, mollusks,
echinoderms, ascidians, elasmobranchs, teleosts, and amphibians. Four chapters focus
on the technological and aquaculture aspects, in particular relating to fishes.
This book is
designed for people who are neither experts/well-read/knowledge-able in the
field of reproductive biology nor aquaculture. The assumed readers are graduate
students and postgraduates in biology and agricultural sciences and also
non-academics who are interested in the field.
Capítulo 4. Fish sperm maturation, capacitation, and motility activation
L.M. Pérez (2020).
In:
Reproduction in Aquatic Animals. From Basic Biology to Aquaculture Technology.
M. Yoshida and J.F. Asturiano (eds.). Chapter 4, Pp: 47-67. ISBN: 978-981-15-2290-1.
Motility
activation mechanism in fish sperm has been studied only in a few species, and
there are many hypotheses about the mechanism for spermatozoa activation that
need further confirmation.
This review summarizes
the current knowledge on sperm acquisition of capability
to move, happening in the sperm duct (sperm capacitation), and the ionic fluxes
related to motility activation, as well as their relation with the sperm
membrane potential changes
Capítulo 14. Improvements on the
reproductive control of the European eel
J.F.
Asturiano (2020)
In:
Reproduction in Aquatic Animals. From Basic Biology to Aquaculture Technology.
M. Yoshida and J.F. Asturiano (eds.). Chapter 14, Pp: 293-320. ISBN:
978-981-15-2290-1.
A combination of several
factors have produced an intense decline of the European eel populations until
becoming an endangered species, but the European eel is a demanded species with
high market values, and wild glass eels are still the base of
the eel aquaculture.
Nowadays, reproduction in
captivity seems the
only realistic alternative to
reduce the pressure on natural populations and supply glass eels to
eel farms. Altogether,
trying to get
its reproduction in
captivity is still
an exciting scientific
challenge for physiologists, endocrinologists, nutritionists, embryologists, etc.
This chapter tries
to give an
overview of the
recent research developed in some of the key areas related
with the reproduction of this species, and the main improvements, conclusions
and hypothesis emerging from that research, making an especial emphasis in
those papers published from 2000.
