Epigenetics... fascinating entry into this discussion by ifishy. Thankyou! Pulled the following from Prof Google (edited) attempting to gather the "basics": Epigenetic changes, particularly DNA methylation, significantly affect salmon size and reproduction by influencing gene expression in response to environmental factors. Research on both wild and farmed salmon shows that factors like temperature, stress, and nutrition can alter an individual's growth and timing of maturation. These changes can sometimes be passed to offspring, impacting future generations. Factors causing epigenetic changes: Captive vs. wild rearing A central area of study compares the epigenetics of hatchery-raised salmon with their wild counterparts. Reprogramming fitness: Captive rearing induces distinct DNA methylation patterns in salmon, including regions associated with stress response, immune function, and neuro-muscular regulation. Reduced fitness: These epigenetic changes likely contribute to the reduced survival and reproductive success observed in hatchery-reared fish when released into the wild, even in the absence of significant genetic differences. Transgenerational inheritance: Research has shown that these environmentally-induced epigenetic marks can persist into adulthood and be transmitted to offspring through the sperm, potentially affecting the fitness of future generations. Competition and nutrition Environmental conditions at sea, such as competition for food, are a major driver of changes in salmon size and age at maturation. Food availability: Increased competition from other salmon populations in the ocean can limit food resources. This affects overall growth rates, causing fish to be smaller at a given age. Age structure: A more significant factor in overall size decline, however, is a shift toward younger maturation. Under stressful oceanic conditions, salmon are returning to spawn at younger ages, and therefore at smaller sizes. Feed composition: In aquaculture, manipulating micronutrients in feed can induce changes in gene expression and DNA methylation related to growth and metabolism. These changes can also be inherited by offspring. Impact on reproduction and size The epigenetic changes driven by these environmental and rearing factors directly impact salmon fitness and survival. Reproductive cycles: Manipulating environmental factors like light and water temperature can artificially alter the spawning seasons of Atlantic salmon broodstock for aquaculture, showing how sensitive their reproductive cycles are to environmental cues. Egg production: The widespread declines in salmon body size due to younger maturation can lead to a significant reduction in per-capita egg production, threatening the sustainability of salmon populations. Intergenerational effects: Epigenetic modifications in the sperm and eggs due to stress can affect metabolic rates and physiology in the offspring, influencing their growth, development, and overall fitness.

The Braddock Bay channel is now open for use, dredging complete.... I was out cycling by Westpoint Marina this afternoon and noticed the dredge tied up and workers off loading piping. I inquired with regard to completion and one of the workers advised they were finished, with the channel open for use. Present depth is 4' - 6'.
