Abstract:

There were no signs of overt toxicity in sexually mature female lake trout (Salvelinus namaycush) exposed to either a control or a 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-containing diet for 11 wk prior to spawning. At spawning the maternally derived egg TCDD concentrations were 42 ± 4 and 43 ± 6% of the maternal skeletal muscle TCDD concentration on a lipid and wet weight basis, respectively. Egg TCDD concentrations of 233–387 pg TCDD/g egg (wet weight) resulted in nonviable oocytes, while concentrations of 50–152 pg/g resulted in a dose-related increase in sac fry mortality associated wit

Spatio-temporal variability in western Baltic cod early life stage survival mediated by egg buoyancy, hydrography and hydrodynamics. – ICES Journal of Marine Science, 69: 1744–1752. To disentangle the effects of different drivers on recruitment variability of marine fish, a spatially and temporally explicit understanding of both the spawning stock size and the early life stage dynamics is required. The objectives of this study are to assess the transport of western Baltic cod early life stages as well as the variability in environmental

A hydrodynamic model coupled with a Lagrangian particle tracking technique was utilized to simulate spatially and temporally resolved long-term environmentally related (i) size of habitat suitable for reproduction, (ii) egg/yolk-sac larval survival, (iii) separation of causes of mortality, and (iv) connectivity between spawning areas of Baltic flounder with pelagic eggs.

Abstract:

A mechanistic temperature-dependent model for preemergent growth coupled with spawning and river temperature data is used to evaluate early life history strategies for chinook salmon (Oncorhynchus tshawytscha) in the Methow River, Washington, U.S.A. Since the model provides a predictable coupling between time of spawning and fry emergence, it helps explain the spatial and temporal patterns observed for the sympatric stocks. The model suggests that progeny of August-spawning chinook in upper river habitats emerge at button-up (no visible yolk sac) over a wide range of days in the early spring.

Abstract:

Abstract The protracted spawning period of broadcast-spawning marine fishes has potential to generate considerable variability in metrics of individual reproductive output. We undertook a temporally detailed genetic study of larvae produced by Atlantic cod (Gadus morhua) from two spatially proximate populations spawning under controlled semi-natural conditions over 94 days. Based on daily samples of larvae (n = 4489 in total), we document fine-scaled temporal changes in, and correlates of, offspring phenotype and reproductive output (egg batches produced or fertilized).

Abstract:

Different life-history stages of the pelagic harpacticoid <em>Microsetella norvegica</em> were sampled in a Greenland fjord, to investigate how this slowly growing species can achieve high abundances at low temperatures. We expected low but continuous reproduction coupled with a low mortality, but observed the opposite: a short reproductive period with high estimated weight-specific egg production and egg mortality, and indication of a life-history strategy combining the advantages of egg carrying with egg production rates independent of temperature.

Abstract:

Through a series of ichthyoplankton surveys carried out off central Chile, we characterize the offshore spawning and coastal nursery ground of the bigeye flounder Hippoglossina macrops. Eggs were collected in higher abundances over the continental shelf during late winter, over the shelf-break in mid spring, and at the continental slope in late summer, showing a seasonal depth gradient in spawning. No significant spawning was detected nearshore (less than 8 km offshore). Field data suggest a longitudinal progression from offshore to onshore of larval stages from preflexion to transformation st

Abstract:

Timing of spawning and hatching of shortnose sturgeon, Acipenser brevirostrum , in the Saint John River, New Brunswick, Canada, was estimated using inverse prediction. We examined egg incubation periods at 5, 9, and 13 °C to back-calculate spawning dates. No larvae hatched at 5 °C. At 9 and 13 °C, hatching began after 18 and 8 days post fertilization, respectively. Lengths of yolk-sac larvae reared in the laboratory at 13–21 °C were used to develop a temperature-mediated Gompertz growth model. The inverted Gompertz model, predicting larval age from larval size and water temperature, was applie

Abstract:

Population mean egg size of salmonids increases with the mean size of gravels in which a population spawns. A long-standing hypothesis is that large larvae cannot navigate small-gravel interstices, so mothers must decrease per-offspring investment when spawning gravels are small. We manipulated the size of incubation gravels and egg size of Atlantic salmon (Salmo salar) to test whether size-related entombment of larvae occurs. We find little evidence of size-related entombment, but we find evidence that gravel size does not affect all larval sizes equally. Larger larvae emerge from small grave

Since 1990–1991, disturbances in the behavior of spawning migrating Baltic salmon have been observed. This study found a strong correlation between wiggling behavior in adult female Baltic salmon and the development of M74 in their offspring. Moreover, the ovarian thiamine concentrations in

Abstract:

Abstract Female copepods do not spawn massively once then die, like squid or salmon. When mature and mated, they spawn numerous times. Amounts, rates, and longevity of egg production have been observed for many species under varied conditions of temperature and food availability. Two strategies dominate: free release of numerous eggs into the water vs. carrying fewer eggs to hatching of in membrane sacs secreted at the genital opening. Sac spawning provides the protection of the predator escape capacity of the female towing her eggs. Roughly three-times more eggs are required and provided by f

Abstract Anadromous fishes hatch and develop in freshwater (FW) and migrate to seawater where they spend most of their life before returning to FW for spawning. In contrast to trout, most salmon are anadromous. Atlantic salmon (Salmo salar) dominates aquaculture of anadromous fishes and is produced mainly in its native distribution range. Most Pacific salmon are produced in the Southern hemisphere, outside their native distribution range. Salmon aquaculture consists of a FW hatchery phase and a seawater grow-out phase. These different culture phases are required for all anadromous species. The

Smooth skin, small eyes, a large, tapering operculum flap, bluish- gray to black coloration dorsally, and a deeply forked heterocercal caudal fin all serve to distinguish paddlefish from other species.
