Smallmouth Behavior: The Solar Eclipse
The solar eclipse is coming…..
We are about to witness and experience the next solar eclipse but we will not experience this alone. So to will our Smallmouth Bass populations throughout the region. Many will say that because the time frame of an eclipse is so limited that it will not impact bass much but coupled with what we have happening in our region right now with virtually every major river up three times or more than its normal depth levels this one could be very different.
Not only are the Smallmouth being scattered throughout the river system and often up on blown out bank areas now flooded bass are now about to experience a double whammy of sorts with a change that lets face most have yet witnessed in their life times.
Will these events turn on the feeding frenzy or shut the entire bass populations down and determine to wait things out?
The Algonquin peoples referred to the April moon as the Full Fish Moon or Pink Moon while some also call April the Kàwàsikotòdj Kìzis, Breaking Ice Moon in the northern regions makes sense given the plight of Smallmouth anglers until after the thaw of lakes from winter in Spring.
We know how or at least we think we do how the lunar phases impact Smallmouth. I for one have changed camps now that I have had the opportunity to fish far more the last five years on our river systems. I used to believe that spawn was triggered only by water temperatures but now I have crossed over the the dark side. I have come to accept that the key factor is that last lunar phase typically of the month of April that triggers the beginning of spawn in many areas. Crazy speak I know but I have seen Smallmouth spawn in temperatures that are totally outside the range we have come to accept as the norm. The constant has been the lunar cycle.
Solar eclipses can have various effects on the behaviors of black bass, which are a type of freshwater fish known for their sensitivity to changes in light and environmental conditions. Here's how a solar eclipse may impact black bass behavior:
Light Levels: During a solar eclipse, there is a sudden reduction in light as the moon passes in front of the sun. This can mimic the onset of dusk or dawn, causing black bass to become more active. Bass are known to be crepuscular feeders, meaning they are most active during low-light conditions. Therefore, they may take advantage of the decreased light during an eclipse to hunt for prey.
Temperature Changes: Solar eclipses can also cause a drop in temperature, albeit usually a slight one. This temperature change can affect the water temperature in lakes or rivers where black bass reside. Cooler temperatures may prompt black bass to move to shallower waters or change their feeding patterns.
Confusion: Animals often exhibit confusion during a solar eclipse because sudden changes in light and temperature can disrupt their normal routines. Black bass may become disoriented or uncertain about their surroundings, which could affect their behavior. Some fish may become more cautious and retreat to cover, while others may become more aggressive in their feeding habits.
Altered Feeding Patterns: The decrease in light during a solar eclipse may prompt black bass to adjust their feeding patterns. They may become more opportunistic and aggressive in their pursuit of prey, as they take advantage of the cover provided by the dimmed light to ambush unsuspecting prey.
Reproduction: There is some anecdotal evidence to suggest that solar eclipses may influence fish spawning behavior. While research in this area is limited, it's possible that the changes in light and temperature during an eclipse could impact the timing or intensity of black bass spawning activities.
Overall, while solar eclipses may not have a dramatic or direct impact on black bass behavior, they can certainly cause subtle changes in their environment that may influence their feeding, movement, and reproductive activities. As with any natural phenomenon, the extent of the impact will likely vary depending on factors such as the local ecosystem, weather conditions, and individual fish behavior.
How will a solar eclipse impact or even differ than normal lunar phases in terms of impacts on Smallmouth behaviors?
A solar eclipse can impact tides and river systems in several ways:
Gravitational Pull: The gravitational pull of the sun and moon is what primarily influences tides. During a solar eclipse, the alignment of the sun, moon, and Earth can temporarily disrupt this gravitational equilibrium. While the effect of a solar eclipse on tides is generally minor compared to the influence of the moon, there can be subtle variations in tide heights during an eclipse.
Tidal Range: The gravitational forces exerted by the sun and moon work in tandem to create tides. During a solar eclipse, when the moon passes between the Earth and the sun, it can momentarily interfere with these forces. This interference may result in a temporary decrease in the tidal range, particularly in areas where the eclipse is most visible.
River Flows: Tidal effects can propagate upstream in river systems, especially in estuaries where tidal influence is significant. During a solar eclipse, any alterations in tidal patterns can affect the flow of water in rivers and estuaries. This may lead to temporary changes in water levels and currents.
Temperature Changes: Solar eclipses can cause a temporary decrease in temperature due to the blocking of sunlight. This cooling effect can influence the behavior of water bodies, including rivers. Changes in temperature can affect water density and circulation patterns, which in turn may impact river flows and mixing processes.
Ecological Impacts: Tidal variations and changes in water temperature and flow can have ecological consequences for river ecosystems. For example, fluctuations in water levels may affect the distribution and behavior of aquatic species, including fish and invertebrates. Additionally, changes in temperature and flow dynamics can alter nutrient cycling, habitat availability, and other ecological processes.
It's important to note that the effects of a solar eclipse on tides and river systems are relatively short-lived and localized. Once the eclipse passes and normal astronomical conditions resume, tidal patterns and river flows typically return to their usual states.
Nonetheless, solar eclipses provide scientists with opportunities to study the interactions between celestial phenomena and Earth's natural systems, including its oceans and rivers and the fish and species that live in them like our Smallmouth.
Normal lunar phases throughout the year can have various impacts on the behaviors of Smallmouth Bass in river systems. Here's how lunar phases may influence Smallmouth bass behavior:
Feeding Patterns: Smallmouth bass, like many other fish species, are often more active during low-light conditions, such as dawn, dusk, and at night. During certain lunar phases, such as the new moon and full moon, there can be significant changes in light levels. The new moon, when the moon is not visible in the sky, provides darker nights, while the full moon illuminates the water more brightly. Smallmouth bass may adjust their feeding patterns accordingly, becoming more active during low-light periods and feeding more aggressively during the darker nights of the new moon.
Movement and Location: Lunar phases can also influence the movement and location of Smallmouth bass within river systems. During periods of increased light, such as the full moon, Smallmouth bass may move to deeper water or seek cover to avoid predation and maintain their hunting advantage. Conversely, during darker nights, they may venture into shallower areas or move more freely in search of prey.
Spawning Behavior: Lunar cycles can play a role in Smallmouth bass spawning behavior. Smallmouth bass often spawn during the spring months, and lunar phases can influence the timing and intensity of spawning activities. Some research suggests that Smallmouth bass may prefer to spawn during specific lunar phases, such as the new or full moon, possibly due to the associated changes in light and water temperature.
Predator-Prey Dynamics: Lunar phases can affect the behavior of both Smallmouth and their prey species. For example, certain aquatic insects and other prey may be more active during specific lunar phases, influencing the feeding opportunities available to Smallmouth bass. Changes in prey availability and behavior can, in turn, impact the feeding strategies and movement patterns of Smallmouth.
Environmental Factors: Lunar phases can indirectly influence Smallmouth bass behavior by affecting environmental factors such as water temperature, water clarity, and current flow. These factors can interact with lunar cycles to create optimal or suboptimal conditions for Smallmouth bass feeding, movement, and spawning activities.
Overall, while the influence of lunar phases on Smallmouth bass behavior may be subtle and complex, it is an important factor to consider for anglers and researchers studying the ecology of river systems. Understanding how lunar cycles interact with other environmental variables can provide insights into the behavior and dynamics of Smallie populations throughout the year.
