ΝΕΟ ΒΙΒΛΙΟ: ΘΑΛΑΣΣΙΑ ΒΙΟΛΟΓΙΑ (Μετάφραση Castro & Huber)

Το βιβλίο Marine Biology των P. Castro και M.E. Huber κυκλοφόρησε για πρώτη φορά στα Αγγλικά το 1992. Η πρώτη απόπειρα παρουσίασης του στο ελληνικό κοινό, το 1999, υπήρξε ιδιαίτερα επιτυχής. Με το πέρασμα των χρόνων και την εξέλιξη της επιστήμης, πολλά πράγματα άλλαξαν και η 9η έκδοση του βιβλίου έρχεται να συνοψίσει τη σύγχρονη γνώση για τους ωκεανούς, τη ζωή σε αυτούς και την αλληλεπίδραση τους με τον άνθρωπο. Πιστεύουμε ότι η μετάφραση της νέας έκδοσης που παρουσιάζουμε σήμερα στο ελληνικό κοινό θα εμπνεύσει ακόμη περισσότερο το ενδιαφέρον για τη μελέτη αλλά και την προστασία της θάλασσας.

Understanding the determinate–indeterminate fecundity dichotomy in fish populations using a temperature dependent oocyte growth model

Understanding the determinate–indeterminate fecundity dichotomy in fish populations using a temperature dependent oocyte growth model

Highlights

•

We modeled the fecundity type in fishes based on the relationship between oocyte growth period and duration of spawning.

•

Simulations showed that stocks with OGP longer than the SP are predicted to exhibit determinate fecundity and vice versa.

•

Oocyte size frequencies and time trends in fecundity match descriptions for determinate and indeterminate spawners.

Abstract

The fecundity type (determinate vs. indeterminate) is still uncertain for many commercially important fish populations affecting accuracy in fecundity estimations and hindering the selection of appropriate egg production methods for stock assessment purposes. It is broadly considered that boreal fish populations living in colder habitats are determinate spawners whilst populations residing in warmer habitats tend to be indeterminate spawners. In the present study we modelled the determinate–indeterminate fecundity type in batch spawning fishes, i.e. fish that spawn several batches of eggs per spawning season, based on the relationship between oocyte growth period and the duration of the spawning period considering that both variables can be affected by water temperature and latitudinal distributions. Individual based models (IBMs) were developed to explore how the interaction of these variables can result in a series of patterns along the continuum from extreme determinacy, i.e. annual fecundity being recruited long before the onset of the spawning period, to indeterminacy. Model simulations showed that fish stocks with oocyte growth periods longer than the spawning period are predicted to exhibit determinate fecundity which provides a fair justification for why cold water species with slow oocyte growth and limited spawning periods are determinate spawners and vice versa.

BRIEF DESCRIPTIONThe chapter deals with the estimation of female fecundity in fishes, mostly teleosts. The chapter is organized in three main blocks. The first block is devoted to technical issues of fish fecundity measurements from fixation, preservation and treatment of ovarian material to automatic oocyte counts. The use of certain staining protocols for the identification of follicular types in ovarian whole mounts and of inexpensive equipments in oocyte counting is also described. Because histology still constitutes the most unbiased method for identifying ovarian structures an array of stereological methods for estimating follicular intensity from assumption/model based methods (e.g. Weibel and oocyte packing density (OPD) method) to assumption/model free methods such as the physical disector or the fractionator principle is also provided. The second block is focused on methods used for the estimation of important variables such as batch fecundity (using hydrated oocytes and or previous developmental stages), daily fecundity and spawning fraction, S. Special emphasis is given to the estimation of S; the postovulatory follicle (POF) method is explicitly described together with its most common bias issues related to POF staging and ageing. In addition, methods that are based on imminent spawners, methods for stocks with high S values, and methods based on the assessment of spawning sites are also descibed. The third block incorporates knowledge acquired in the two other blocks to review what is needed to estimate the annual realized fecundity (the ultimate goal of fecundity studies) in determinate and indeterminate fish species. The autodiametric method for estimating potential annual fecundity, and the impacts of fecundity dowregualtion by atresia and of skipped-spawning in determinate spawners are also included. In short, this chapter will offer the reader an overview of all methodological aspects that need to be considered in fish fecundity investigations.

BIOLOGY AND ECOLOGY OF SARDINES AND ANCHOVIES

NEW BOOK RELEASED IN MARCH 2014 FROM CRC PRESS
Edited by K. Ganias
Biology and Ecology of Sardines and Anchovies - CRC Press Book

DESCRIPTION
Apart from being commercially and socially significant, anchovies and sardines populations occupy crucial positions in the oceans’ ecosystems. Low in the food chain, clupeoids tend towards abundance, as if their purpose in life was to be eaten and fuel the upper levels of marine trophic chains. The present book covers a broad spectrum of topics on the biology (sytematics, phylogeography, reproduction, feeding) and ecology (habitat characterization, recruitment variability) of anchovies and sardines. It also puts together important information on the state of their fisheries, exploitation and management.
