Biophysical models reveal the role of tides, wind, and larval behaviour in early transport and retention of Atlantic herring (Clupea harengus) in the Celtic Sea
Canadian Journal of Fisheries and Aquatic Sciences - Tập 77 Số 1 - Trang 90-107 - 2020
Inge Deschepper, Kieran Lyons, Olga Lyashevska, Deirdre Brophy
Fish are adapted to spawn where their larvae will be retained in, or transported to, suitable juvenile habitat. Variability in circulation and behaviour produces variation in larval transport with consequences for recruitment. A biophysical model was used to simulate early larval dispersal of Celtic Sea herring (Clupea harengus) during wintertime in 6 years (2002, 2003, 2004, 2005, 2008, ...... hiện toàn bộ
Modelling the dispersal and mortality of Browns Bank egg and larval haddock (Melanogrammus aeglefinus)
Canadian Journal of Fisheries and Aquatic Sciences - Tập 57 Số 12 - Trang 2519-2535 - 2000
David Brickman, Kenneth T. Frank
An early life stage model is described with constant mortality for egg and larval stages. The model is used to simulate the stage 4 egg and larval data for haddock (Melanogrammus aeglefinus) in southwest Nova Scotia for the years 1983-1985. The model is initialized using published abundance and mortality estimates for these years, and its output is compared with field data. We find that t...... hiện toàn bộ
Evolutionary individual-based model for the recruitment of anchovy (Engraulis capensis) in the southern Benguela
Canadian Journal of Fisheries and Aquatic Sciences - Tập 59 Số 5 - Trang 910-922 - 2002
Christian Mullon, Philippe Cury, Pierrick Penven
Evolutionary simulations are developed to explore environmental constraints that select observed spatial and temporal spawning patterns for anchovy (Engraulis capensis) in the southern Benguela. They couple a realistic three-dimensional hydrodynamic model with an individual-based model in which an evolutionary-based reproductive strategy for adult fish and a passive transport for early li...... hiện toàn bộ
Using an individual-based model of fish assemblages to study the response of size spectra to changes in fishing
Canadian Journal of Fisheries and Aquatic Sciences - Tập 61 Số 3 - Trang 414-431 - 2004
Yunne‐Jai Shin, Philippe Cury
For most fish species, strong environmental constraints imposed by living in an aquatic medium have produced converging streamlined body forms without prehensile appendices. This similarity in body shapes highlights a common predation constraint: a predatory fish must have a jaw large enough to swallow its prey. Fish diets may then reflect local prey availability and predator–prey size ra...... hiện toàn bộ
Osmoregulatory plasticity of the glass eel ofAnguilla anguilla: freshwater entry and changes in branchial ion-transport protein expression
Canadian Journal of Fisheries and Aquatic Sciences - Tập 61 Số 3 - Trang 432-442 - 2004
Jonathan M. Wilson, Carlos Antunes, Patrício Bouça, J. Coimbra
The glass-eel stage of the life history of Anguillid eels (Anguilla spp.) makes the important physiological transition from seawater (SW) to freshwater (FW) osmoregulation. Central to successful adaptation to fresh water is the switch from active hypoosmoregulation (ion excretion) to active hyperosmoregulation (ion uptake) to counter passive fluxes imposed by concentration gradients.

Plasma Cortisol Levels of Fingerling Rainbow Trout (Salmo gairdneri) at Rest, and Subjected to Handling, Confinement, Transport, and Stocking
Canadian Journal of Fisheries and Aquatic Sciences - Tập 37 Số 5 - Trang 805-811 - 1980
Bruce Barton, Richard Peter, C. R. Paulencu
Fingerling rainbow trout, acclimated to hatchery raceways or laboratory aquaria, had low plasma cortisol levels (≤ 2 ng/mL), with no apparent daily cycle in levels. Netting of cohorts out of an aquarium, without agitation, did not cause a rise in plasma cortisol concentrations in remaining fish. However, following 90 s of handling and confinement by netting, fingerlings had a sharp rise i...... hiện toàn bộ
Effect of Body Form and Response Threshold on the Vulnerability of Four Species of Teleost Prey Attacked by Largemouth Bass (Micropterus salmoides)
Canadian Journal of Fisheries and Aquatic Sciences - Tập 43 Số 4 - Trang 763-771 - 1986
Paul W. Webb
Experiments were performed using four prey species (fathead minnow, Pimephales promelas, largemouth bass, Micropterus salmoides, bluegill, Lepomis macrochirus, and tiger musky, Esox sp.) with various body and fin forms attacked by largemouth bass predators to determine how body and fin morphology, performance, and response thresholds influenced prey vulnerability. Prey differed in three fa...... hiện toàn bộ
Phosphorus loading reductions needed to control blue-green algal blooms in Lake Mendota
Canadian Journal of Fisheries and Aquatic Sciences - Tập 55 Số 5 - Trang 1169-1178 - 1998
Richard C. Lathrop, Stephen R. Carpenter, Craig A. Stow, Patricia A. Soranno, John C. Panuska
We evaluated the reductions in P loading needed to control blue-green algal blooms in Lake Mendota, Wisconsin. After developing a 21-year loading data set, we used a P mass balance model expressed as a difference equation with an annual time step indexed from mid-April. We defined and estimated a loss parameter lambda as the proportion of the lake's April P concentration lost through sedi...... hiện toàn bộ
Biochemical correlates of growth and condition in juvenile Atlantic cod (Gadus morhua) from Newfoundland
Canadian Journal of Fisheries and Aquatic Sciences - Tập 55 Số 7 - Trang 1591-1598 - 1998
Patrice Couture, Jean‐Denis Dutil, Helga Guderley
The aim of this study was to examine how the biochemical composition of tissues varied with growth rate and condition in juvenile Atlantic cod (Gadus morhua) caught in the wild and kept in captivity. The hepatosomatic index, brain water content, and muscle sarcoplasmic protein content as well as the activities of phosphofructokinase, lactate dehydrogenase, nucleoside diphosphate kinase, an...... hiện toàn bộ
Substock variation in reproductive traits in North Sea cod (Gadus morhua)
Canadian Journal of Fisheries and Aquatic Sciences - Tập 67 Số 5 - Trang 866-876 - 2010
Marion Harrald, P.J. Wright, Francis Neat
The North Sea stock of Atlantic cod ( Gadus morhua ) is comprised of a number of subcomponents that differ both genetically and phenotypically. A potential cause for such spatial variability is adaptive divergence, which may be linked to differences in thermal environment and (or) historical fishing pressure. Here we present evidence that spatial variation in maturity–size relationships in...... hiện toàn bộ
