Bomb dating and age determination of large pelagic sharks
(Journal article; Peer reviewed, 2002)Despite their notoriety and role as apex predators, the longevity of large pelagic sharks such as the porbeagle (Lamna nasus) and shortfin mako (Isurus oxyrinchus) is unknown. Vertebral growth bands provide an accurate indicator ... -
Environmental influences on the recruitment process inferred from otolith stable isotopes in Merluccius merluccius off the Balearic Islands
(Journal article; Peer reviewed, 2008-08-13)Oxygen (δ18O) and carbon (δ13C) isotope ratios in sagittal otoliths were analysed in recruits and juveniles of European hake Merluccius merluccius L. caught in the northwest (Sóller, SO) and south (Cabrera, CA) of the ... -
Growth and mortality patterns evaluated from otolith microstructure in Atlantic cod Gadus morhua larvae reared on different feeding regimes in mesocosms
(Journal article; Peer reviewed, 2003-12-15)The objective of this work was to test the hypothesis that in a situation where predators are excluded growth and mortality rates of cod larvae should be independent. This was evaluated from distributions of otolith ... -
Shedding Light on Fish Otolith Biomineralization Using a Bioenergetic Approach
(Journal article; Peer reviewed, 2011-11-14)Otoliths are biocalcified bodies connected to the sensory system in the inner ears of fish. Their layered, biorhythm-following formation provides individual records of the age, the individual history and the natural ... -
Temperature effect on growth and larval duration of plaice Pleuronectes platessa in three regions of the Northeast Atlantic
(Journal article; Peer reviewed, 2013-02-27)Transport models for planktonic fish eggs and larvae often use temperature to drive growth because temperature data are readily available. This pragmatic approach can be criticised as too simplistic as it ignores additional ...
