Persistent effects of incubation temperature on muscle development in larval haddock (Melanogrammus aeglefinus L.).

Muscle development and growth were investigated in haddock larvae (Melanogrammus aeglefinus L.) incubated under controlled temperatures (4, 6, 8 degrees C) and reared post-hatch through yolk-dependent and exogenous-feeding stages in a 6 degrees C post-hatch environment. Changes in cell number and size in superficial and deep myotomes within the epaxial muscle were investigated for 28 days follo...

A trans-Atlantic examination of haddock Melanogrammus aeglefinus food habits.

The food habits of Melanogrammus aeglefinus were explored and contrasted across multiple north-eastern and north-western Atlantic Ocean ecosystems, using databases that span multiple decades. The results show that among all ecosystems, echinoderms are a consistent part of M. aeglefinus diet, but patterns emerge regarding where and when M. aeglefinus primarily eat fishes v. echinoderms. Melanogr...

Effects of seismic shooting on local abundance and catch rates of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus)

To determine whether seismic exploration affected abundance or catch rates of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus), acoustic mapping and fishing trials with trawls and longlines were conducted in the central Barents Sea 7 days before, 5 days during, and 5 days after seismic shooting with air guns. Seismic shooting severely affected fish distribution, local abundance, and ca...

DNA damage in dab (Limanda limanda) and haddock (Melanogrammus aeglefinus) from European seas.

Dab (Limanda limanda) and haddock (Melanogrammus aeglefinus) were collected from coastal and offshore locations in the Baltic (dab only), North Sea (haddock from one location only) and Iceland. Blood was analysed for DNA strand breaks using the comet assay and liver samples for DNA adduct concentrations. DNA strand breaks were at background levels in dab from the two Iceland locations and from ...

Effects of different incubation temperature on development rate, growth, survival and some physiological parameters during embryonic and larval development in Rainbow trout (Oncorhynchus mykiss)

Temperature is one of the most important environmental factors affecting of fish embryos and the survival and growth of fish larvae. In this study, eyed eggs of rainbow trout were incubated and reared until 30 day after first feeding at three constant temperatures including 7, 11 and 15 °C with four replicates in order to observe their survival, growth, rate of development and some physiologica...
