there was a study done various time with gold fish by various university in the east coast, as well as three in Europe, using various species. The results were similar, if not exactly, the same exhibit traits:
1. Max short term memory of 8 hours, during foraging/feeding cycle. No long term memory retention recorded. Using maze method, the fish species was able to learn the different paths to the same feeding zone. However, when the fish left to resume their normal activities more than 24 hours, and resubjected the same experiment, the fish require retraining for a good 48 hours before they reacquired the memory skill to navigate the mazes.
2. Pond owners acknowledged species of rock bass, greenies, and panfish becoming hooks' shy, after exposing them to various captures using different baits/lures, with in between periods of 48 to 72 hours. However, this is only recorded in ponds, since ponds are isolated water body which schools of fish react universally to leading fish (larger, more experience males/females). There was no record of tagged fish that had been captured various time in larger water, such as the bays, but there's noticeable info reported by anglers for larger bass from fresh water lakes, such as Lake Perris, Big Bear Lake, exhibiting wounds from previous encounters with anglers. Regular Texas, Carolina, dropshot rigs with plastics would not be enough to catch these larger fish. However, trickeries using Cal-Alabama rigs, or shakey heads hooks with more convincing life-like bait fish that hide the hooks completely were the only thing that manage to land the trophy size fish.
So, there's a definite learning curve to the different species, as well as the years of exposure to capture rates for being hooks' shy. Not enough documentation to provide a definitive answer, but the answer is coming out of the darkness. I've been collecting the information over the last 3 decades about this subject as well. It interested me after learning the aquafauna cultures and their annual rituals in high school, with genetic imprints to new generations of their experiences and knowledge acquired.
