Growth pattern and growth dependent mortality of larval and pelagic juvenile North Sea cod Gadus morhua
We investigated growth patterns and evidence of growth dependent survival for a population of Atlantic cod Gadus morhua using analysis of their otolith microstructure. Central concentrations of a population of cod larvae and juveniles in the north-eastern North Sea were sampled twice (in April and May 2001), and larval/juvenile growth history from each of the sampling sequences was outlined. Gr...
متن کاملUsing otolith microstructure to analyse growth of juvenile Baltic cod Gadus morhua
Pelagic and demersal juvenile Baltic cod Gadus morhua L. were collected on the slope and the top of Rønne bank in the Baltic Sea during 2 cruises in November and December 1998. The growth, age at settling and vertical migration pattern were studied by otolith microstructure analysis. The relationship between fish and otolith size were found to change at settling, with an increase of fish size i...
متن کاملFactors determining variations in otolith microincrement width of demersal juvenile Baltic cod Gadus morhua
Pelagic and demersal juvenile Baltic cod Gadus morhua L. were collected on the slope and the top of Rønne bank in the Baltic Sea during 2 cruises in November and December 1998. The objective of this study was to evaluate distinct changes in otolith increment width observed in demersal juveniles by comparison with laboratory-reared individuals, and to investigate the factors determining variatio...
متن کاملEnhanced protein synthetic capacity in Atlantic cod (Gadus morhua) is associated with temperature-induced compensatory growth.
Atlantic cod (Gadus morhua) were held either at seasonal ambient temperatures (-0.3 to 11 degrees C) or at a relatively constant control temperature (8-11 degrees C) to investigate aspects of protein synthesis during a period of compensatory growth. Protein synthesis rate, total RNA, and RNA-specific protein synthesis rate were determined in white muscle and liver when ambient temperatures were...
متن کاملEffects of ocean acidification on the calcification of otoliths of larval Atlantic cod Gadus morhua
The growth and development of the aragonitic CaCO3 otoliths of teleost fish could be vulnerable to processes resulting from ocean acidification. The potential effects of an increase in atmospheric CO2 on the calcification of the otoliths were investigated by rearing Atlantic cod Gadus morhua L. larvae in 3 pCO2 concentrations — control (370 μatm), medium (1800 μatm) and high (4200 μatm) — from ...
