Nightcrawlers are a popular choice for bait when it comes to fishing. These large earthworms are highly sought after by anglers due to their size and ability to attract different types of fish. However, sometimes anglers have more nightcrawlers than they can use in one outing. This leads to a common question – how long will nightcrawlers live in the refrigerator? In this article, we will provide you with a guide on preserving your bait and ensuring that your nightcrawlers stay alive and healthy for as long as possible.
Understanding the Lifespan of Nightcrawlers
Nightcrawlers, also known as Lumbricus terrestris, have a lifespan that can vary depending on various factors. In their natural habitat, nightcrawlers can live for up to six years. However, when kept in captivity, their lifespan is significantly shorter. In refrigerated conditions, nightcrawlers can typically live for around two to three weeks.
Temperature and Humidity
One of the most important factors when it comes to preserving nightcrawlers is the temperature. Nightcrawlers thrive in cool and moist environments. The ideal temperature for their preservation is between 35 to 45 degrees Fahrenheit (1 to 7 degrees Celsius). If the temperature drops below freezing or exceeds 50 degrees Fahrenheit (10 degrees Celsius), it can be detrimental to the health and survival of the nightcrawlers.
Humidity is another crucial aspect to consider. Nightcrawlers require a certain level of moisture to survive. If the environment becomes too dry, the nightcrawlers will quickly dehydrate and die. Keeping the humidity levels high by placing a damp cloth or paper towel in the container can help maintain the necessary moisture for their survival.
Choosing the Right Container
Selecting the appropriate container is essential when it comes to preserving your nightcrawlers. Opt for a container that allows for good air circulation and is not airtight. Nightcrawlers require oxygen to survive, and a lack of airflow can result in their death. It is advisable to use a plastic container with small holes or a breathable container specifically designed for storing live bait.
Additionally, make sure the container is spacious enough to accommodate the nightcrawlers comfortably. Overcrowding the container can cause stress and may result in their demise. As a general guideline, provide at least 2 to 3 inches of space per nightcrawler.
Proper Handling and Feeding
Avoid Excessive Movement
When handling nightcrawlers, it is crucial to minimize excessive movement and agitation. Rough handling or shaking can harm the worms and lead to injuries. Always handle them with care and avoid dropping them, as it can cause internal damage or even death.
Feed the Nightcrawlers
To keep nightcrawlers healthy and alive, it is important to provide them with suitable food. Nightcrawlers are detritivores and primarily feed on decomposing organic matter such as leaves and grass. You can replicate their natural diet by adding small pieces of fruit or vegetable scraps to their container. Ensure that the food is fresh, and do not overfeed them, as excess food can spoil and create an unsuitable environment for the worms.
Emergency Situations: When to Revive Nightcrawlers
Sometimes despite your best efforts, nightcrawlers may appear limp and seemingly lifeless. In these cases, there are methods you can try to revive them, but success is not guaranteed.
Temperature Shock
If the nightcrawlers have been exposed to extreme temperatures, such as accidentally leaving them in hot weather or exposing them to freezing conditions, they may enter a state of shock. To revive them, gradually warm or cool them down to the ideal temperature range. Avoid sudden temperature changes as it can cause further stress.
Overfeeding or Poor Water Quality
If you suspect overfeeding or poor water quality as the cause of distress, gently rinse the worms with cool water to remove any excess food or waste. Replace the old bedding and ensure the new bedding is damp, providing them with cleaner and suitable conditions.
Conclusion
Preserving nightcrawlers in the refrigerator can extend their lifespan and keep them alive for several weeks. Remember to maintain an optimal temperature range, provide sufficient humidity, choose the right container, handle them with care, and ensure they are adequately fed. Follow these guidelines, and you can enjoy the benefits of live nightcrawlers as bait for your fishing adventures for an extended period of time.
