Maybe these schoolers think a feeding frenzy is about to start when they notice the commotion in the water. This also brings up the question of we're these schooling bass once independent? Seasonal patterns, feeding opportunities, or traits passed down from the parent bass could all be possibilities but the idea of communication certainly looms there as well. This is a good topic we have here, I'd like to hear some more on this.
From a biological stand-point, it seems silly to think that a particular man-performed action can get a positive instinctual reaction but not believe another action can get a negative one.
I've been known to release something from time to time that is smelled by others, who then proceed to evacuate the immediate area Valid points about the schooling theory. I never thought of it that way. But in my opinion, whether or not the fish communicate amongst each other, I believe it all comes down to if they are feeding or not.
Sounds simple, but how many times have you pulled up on some structure and the graphs light up, only to not get a single frickin' bite. On the other hand, on the Tennessee those guys will sit on a channel indention the size of a bean bag chair and smack 25 pounds off of it throughout a day. I believe its all about the feeding. You hear those guys say, "I just need to get one to bite", because once one bites in a school, the others don't care if he comes back crying with a sore lip. They are lit and ready to go.
I don't believe for a second that fish actually communicate. If they behave similarly in a scenario, it's more likely simply because they are all wired the same. It stands to reason that if they are all faced with the same stimuli, that they are going to have the same reactions. Now, take into account the individual fish's need for food at that particular time, it would also make sense why one might ite, while another might not.
Bass can be curious and competitive creatures, like many other animals, so when when one makes a commotion while on a hook, it's not unusual for another, or even a couple, to follow, closely. After all, if they're hungry, they don't wanna miss out on a meal.
If, in the future, they become extinct, we will be in deep when their home world sends the probe to figure out why they lost contact. Unless we are able to grab a few from the past to repopulate the species most likely via a slingshot around the sun , chances are the bass probe's communications will destroy the Earth.
Bass are, so far, not known to produce an alarm substance like Shreckstoff substance found in Ostariophysi minnows, catfishes, and some others. And there's been little anecdotal evidence that bass or other Centrarchids produce such a chemical. FYI: Here's a recent article on Shreckstoff:. However, Bob Underwood in his book "Lunker" -describing his hours observing and experimenting with bass in SCUBA gear- had a whole chapter highlighting his observations of bass with torn skin alarming the schools of bass they were caught from.
Mouth hooked fish produced no such response. He did repeated "experiments" and was convinced that tearing the skin of bass alarmed others. As to the more general question of whether bass can communicate with other bass, the answer is yes. But that depends on what they are communicating. One bass or other fish spooking can alarm others nearby.

They feed predominately by sight, but also utilize their sense of smell and lateral line to capture prey Janssen and Corcoran Because M.
Largemouth Bass are voracious feeders and will consume almost any prey they can fit in their mouth and swallow whole.

Journal of Herpetology 20 4 Largemouth bass can be recognized by the lower jaw that extends past the back edge of the eye. It is dark green above with silvery sides and belly and a dark stripe across its body.
The underside ranges in color from light green to almost white. They have a nearly divided dorsal fin with the anterior portion containing nine spines and the posterior portion containing 12 to 13 soft rays.
Largemouth bass have been known to reach weights of over 20 pounds. Find largemouth bass in the St. The species has been introduced widely as a game fish and is now cosmopolitan. Largemouth bass are found in all waters from freshwater to brackish a mix of fresh and saltwater waters. They like large, slow moving rivers or streams with soft bottoms. They especially like clear water. Males generally don't greyish color.
They have a deep notch between their dorsal fins, along with a dark black exceed 40 cm long, but the females can reach up to 56 cm long. The color of largemouth bass is generally olive-green, but some have been reported to be a stripe along their body.
This bass has a large mouth that extends beyond the posterior edge of their eye which is what tends to separate them from other species, such as the smallmouth bass, Micropterus dolomieu. They also have a clear separation between the first and second dorsal fins. The front fin has nine to eleven spines while the back fin has up to twelve to fourteen rays. The fry, at hatching are about mm long.
Page and Burr, ; Rainer and Luna, Fertilized largemouth bass eggs are yellowish orange in color. Largemouth bass fry hatch depending on the water temperature in the nest. They usually take days at degrees Celsius, but can days when temperatures are degrees Celsius. After the eggs hatch the fry form a school and are protected by the male adult while they stay in the nest for days.
The fry then absorb their yolk sacs and can swim on their own. Both sexes grow indeterminately about cm during their first year. The second year this species grows about 10 cm, and they continue to grow about 5 cm a year until they are 6 years of age. At this point the growth rate decreases but does not cease.
Johnke, ; Von der Emde, et al. Largemouth bass are polyandrous, which means one female mates with multiple males in a single breeding season. They reproduce once per year in January-March in the southern areas, and May-June in the northern parts.
Males prepare the nest at the bottom with hard packed sand, pea-gravel, clay, or marl with a very thin layer of mud covering the material. Females wait in areas of deeper water for the nests to be finished. Once the water reaches 15 degrees Celsius, spawning can commence. Once the nest is completed, the male then seeks out for a female and brings her to the nest to drop her eggs.
Once the two are near the nest together, the male tries to make her stay by swimming circles around the nest. He also encourages her to drop her eggs by bumping into her numerous times. Once the eggs are dropped the male externally fertilizes them.
Largemouth bass spawn in late winter in the southern parts of the U. Dewoody, et al. Largemouth bass typically spawn in late winter, January-February, in the southern parts of the U. They spawn in water usually 0. Both males and females reach sexual maturity at months of age, though 5 months is the average. Males and females mate until they are about 12 years old.
One female can produce anywhere from 3,, offspring at once but the average is 4, The amount of eggs a female lays is positively influence by her size. Females lay the eggs in the nest that the male has constructed for them and he then externally releases his sperm to fertilize the eggs.
Eggs hatch in days, with those in warmer waters hatching more quickly. Largemouth bass fry reach independence in days but can take as long as 5 weeks. Not much is known on the birth mass of largemouth bass fry, but they average around mm long at birth.
Hambright, et al. Male largemouth bass prepare the nest for their fry. Once fertilized by the female, the male guards the nest, fanning the water to keep silt from building on top of the eggs. The fry then hatch and the males protect their hatchlings.
The adult largemouth bass gets hungry about 4 or 5 days after the fry have hatched and try to eat as many as his own fry as possible. After about days, the fry that survive are ready to swim on their own and depart from their father. Johnke, The average wild lifespan of the largemouth bass is 16 years, with a reported range of years.
The average lifespan of the bass in captivity is years. The maximum lifespan in captivity is unknown. Carey and Judge,
