Learning outcomes

At the end of the course the student acquires the basis for a correct methodological approach applicable to different sampling phases and is able to recognize the macro-microscopic features of organs and tissues and the main biometric parameters of aquatic animals of commercial interest. In particular, he is able to plan, at the fish farm, the collection of anatomical and histological samples, and is able to prepare and critically observe histological preparations. In addition, the student acquires the ability to know the biometric parameters within the supply chain specifications. It has the basis for processing data obtained during zootechnical experiments.

Course contents

This course is part of the Integrated course in "VALUTAZIONI MACRO-MICROSCOPICHE E BIOMETRICHE APPLICABILI IN ALLEVAMENTO E IN CAPITOLATI DI FILIERA".

The course is aimed at understanding the organization and a correct methodological approach to the various sampling phases of organs and tissues and the main biometric parameters, within the specifications of the supply chain, of aquatic animals of commercial interest.

Module 1

Sampling Methods and Normal Histology of Aquatic Species of Commercial Interest. Recognition of the species, dissection and anatomical recognition of the main organs and tissues, techniques of manipulation and sampling of tissues, processing and preservation of histological samples, preparation of histological and cytological preparation, normal histology of bone and cartilaginous fish, molluscs, crustaceans and echinoderms (hedgehog di mare), morphometric evaluations and application of a histological scoring system.

Readings/Bibliography

Teaching material consists of the suggested textbooks (see below) and of the didactic material put on the specific course website (http://campus.cib.unibo.it [http://campus.cib.unibo.it/] ) or website of the teacher responsible for the course: http://www.unibo.it/sitoweb/m.mazzoni/didattica.

In addition, the didactic material is available at the Secretariat of the structure.

The suggested textbooks are:

Teaching methods

Teaching consists of 3 CFUs for a total of 21 hours. Of these, 7 hours are dedicated to frontal lessons and 14 hours to practical exercises. Practical exercises are carried out in part using optical microscopes and their respective histological preparations, and in part by dissecting fresh material.

Assessment methods

Verification of learning is done through an oral test. The oral exam aims to test knowledge acquisition under the program of the course. At each student they will be submitted at least three questions for each modul (module I and module II) inherent to the program. The test is considered positive with a score of at least 18/30. In the case of maximum marks (30/30), honors can be attributed. The final grade is the arithmetic mean of the marks obtained in the two didactic modules and is expressed in thirtieths.

Due to pandemic situation, the student could require to sustain an online oral exam in which she/he should demonstrate to know all the items present in the program and should to be able to link the different arguments, to have a deep knowledge of the topics and to possess an adequate techincal language.

The student has the right to refuse the positive grade proposed once (University teaching regulations ART. 16, paragraph 5)”

EVALUATION OF STUDENTS WITH SPECIAL EDUCATIONAL NEEDS

Particular attention will be given to the evaluation of students certified in accordance with Law 104/90 and Law 170/2010, or students who are recognized as having a special educational need. These students should contact the teacher by email, (cc the personnel form central offices for students with disability or with University SLD (https://site.unibo.it/studenti-con-disabilita-e-dsa/it ). The person in charge of this service in our Department is Dr. Fabiana Trombetti.

The recording teacher is Prof. Mazzoni Maurizio
