Buoyancy of Atlantic cod larvae in relation to developmental stage and maternal influences
The lack of success in predicting the recruitment of fish may to some extent arise from insufficient knowledge of processes affecting egg and larval survival (Chambers and Trippel, 1997). In this context, the quality of eggs and larvae [cf. definitions given in Brooks et al. (Brooks et al., 1997)] and their capacity to develop properly are often mentioned as important factors along with the cor...
متن کاملEstimating Repeatability of Egg Size
—Measures of repeatability have long been used to assess patterns of variation in egg size within and among females. We compared different analytical approaches for estimating repeatability of egg size of Black Brant. Separate estimates of repeatability for eggs of each clutch size and laying sequence number varied from 0.49 to 0.64. We suggest that using the averaging egg size within clutches ...
متن کاملTaqMan DNA technology confirms likely overestimation of cod (Gadus morhua L.) egg abundance in the Irish Sea: implications for the assessment of the cod stock and mapping of spawning areas using egg-based methods.
Recent substantial declines in northeastern Atlantic cod stocks necessitate improved biological knowledge and the development of techniques to complement standard stock assessment methods (which largely depend on accurate commercial catch data). In 2003, an ichthyoplankton survey was undertaken in the Irish Sea and subsamples of 'cod-like' eggs were analysed using a TaqMan multiplex, PCR (polym...
متن کاملEffect of maternal egg consumption on breast milk ovalbumin concentration.
BACKGROUND Maternal dietary avoidance of egg has been recommended to treat egg allergy in breastfed infants. However, only one of three randomized controlled trials have produced evidence in favour of this recommendation. OBJECTIVE Our objective was to assess human milk ovalbumin (OVA) concentration after daily maternal ingestion of one cooked egg for 3 weeks. METHODS Mothers with egg-sensi...
متن کاملEffect of Maternal Egg Consumption on Breast Milk Ovalbumin Concentration
dietitians (45%), and other health care providers (24%). Avoidance of all egg-containing products was recommended to 84%. A subset of the participants reported receiving conflicting advice; 39% reported that they were advised to avoid all egg traces, and 26% were advised that baked egg-containing foods were permitted. Of the 141 of 167 participants who were advised to avoid all egg products, 11...
