The Department of Aquaculture in the Szent Istvan University is organizing a summer school in aquaculture on July 04-09th, 2016. Application is free for students from CEEPUS countries (except travel and insurance costs), however, it is open to citizens of other countries, too for a fee.

This study evaluates the effects of temperature on hCG-induced spermatogenesis in European eel (Anguilla anguilla), subjected to three thermal regimes: T10: 10 °C (first 4 weeks), 15 °C (next 3 weeks) and 20 °C (last 6 weeks); T15: 15 °C (first 4 weeks) and 20 °C (last 9 weeks); and T20: constant 20 °C for the duration of the experiment. At 10 ºC, maturation stopped in the A spermatogonial stage (SPG1), and no further maturation was observed until the temperature was ≥15 ºC. With the aim of explaining these results, the influence of temperature on steroidogenic enzyme gene expression and steroid synthesis was tested. The initial synthesis of androgens (T and 11-KT) increased at SPG1, and was not influenced by temperature. Likewise, the gene expression of the steroidogenic enzymes linked to androgen synthesis (aacyp11a1, aacyp17-I and aa11βHSD) also increased at SPG1. In contrast, no correlation was seen between the increase in E2 and the aacyp19a1 gene expression peak in the testes, with E2 increasing as a consequence of the seawater acclimation carried out before hormonal treatment, and peaking the aacyp19a1 gene expression at B spermatogonial stage (SPG2). Aacyp21 gene expression was also higher at SPG2, and this stage was only reached when the rearing temperature was ≥15 ºC.
In conclusion, androgen synthesis is not dependent on temperature, but further maturation requires higher temperatures in order to induce a change in the steroidogenic pathway towards oestrogen and progestin synthesis. This study demonstrates that temperature plays a crucial role in European eel maturation, even perhaps controlling gonad development during the reproductive migration.
The first announcement for the 6th AQUAGAMETE Training School has just been published!
You can see the details here: http://aquagamete.webs.upv.es/6th-training-school-rennes-france-june-2016/
The course will provide basic knowledge on the use of the zebrafish as a biological model, with main emphasis on its use for the study of human diseases and in research in biology and biomedical sciences. An introduction to genetic manipulation and production of transgenic lines and “knock-out” will be provided. It is intended to provide the students with skills for using the zebrafish in genetic manipulation techniques, use of transgenic and mutants and studies using microinjection and tissue regeneration.
In CCMAR, Faro (Portugal); May 12, 2016.
A new and specific website has been created for announcing the 2nd IMPRESS Workshop and 5th AQUAGAMETE Training School:
You will find further and practical information regarding the event.
The Netherlands has joined the AQUAGAMETE community, which counts, with this incorporation, with 24 COST countries plus 4 non-COST countries. A total of 28 countries!
Thanks to all of you for making this possible!
The first announcement for the 5th Training School, to be held in Valencia (Spain) in March 2016 has just been published here: http://aquagamete.webs.upv.es/5th-training-school-valencia-spain-march-2016/.
Please take a look!
The book of abstracts from the 5th International Workshop on the Biology of Fish Gametes, held in Ancona (Italy) in September 2015 is now available here: http://aquagamete.webs.upv.es/abstracts-books/
“The role of stress coping style in reproduction and other biological aspects in the aquaculture species, Senegalese sole (Solea senegalensis) and gilthead seabream (Sparus aurata)” is the title of the PhD which will be defended by Zohar Ibarra Zatarain the next November 5th, 2015. This work has been supervised by Dr. Neil Duncan and Dr. Joan Carles Balasch, from the Group of Fish Reproduction and Culture (IRTA Sant Carles de la Rapita), Tarragona, Spain.
The defense will take place in the Faculty of Science and Bioscience of the Universitat Autònoma de Barcelona, next Thursday November 5th, at 10:00.
Good luck, Zohar!
POSITION FOR PH.D. STUDENT – TRAINING PROGRAM
ON FISH PARASITOLOGY
The Fish Pathology Group at the Institute of Aquaculture Torre la Sal (Castellón, Spain) is seeking to incorporate a Ph.D. student to conduct a research training program and Ph.D. thesis starting on 2016.
The subject will be the identification molecular targets for the immunoprophilaxis and/or therapy of enteric Myxozoan parasites of cultured fish using genomic/transcriptomic approaches, and the Ph.D.
Thesis will be framed in the EU- funded project
PARAFISHCONTROL: (http://cordis.europa.eu/project/rcn/193286_en.html; www.parafishcontrol.eu)
We are interested in a highly motivated young student (less than 4 years post-graduation) with a competitive profile on life sciences (preferably Fish Microbiology, Parasitology and/or Immunology) and preferably with a solid background on Molecular Biology and Bioinformatics (transcriptomics, insilico gene expression, vaccinology, etc.) and fish pathology.
Our institute belongs to the Spanish “Consejo Superior de Investigaciones Científicas (CSIC), and includes state of the art facilities for basic and applied research on Fish Diseases and other topics related to aquaculture. The position consists on a 3-4 years contract under the general CSIC conditions for Pre-doc positions. A selection commission will consider aspects such as the graduate’s qualifications and CV, motivation, and fitness for the required profile. Candidates must be EU citizens or alien citizens with legal residence in Spain.
The incorporation would be in Jan 2016 or the earliest possible after this date depending of the candidate availability and possible administrative issues.
Candidates are encouraged to submit a brief letter manifesting their motivation and general skills, together with a short CV to Dr. Ariadna Sitjà-Bobadilla (email@example.com) and/or to Dr. Oswaldo Palenzuela (firstname.lastname@example.org).
