I am a pattern fisherman. Pattern fishing works very well for me. Everyday I try and find a pattern within a pattern. It is not easy to find a pattern within a pattern but when you do, it can be some of the most amazing fishing you can experience. For example lets say that that the pattern you have found is that fish are holding on offshore rock piles. You are catching a good amount of quality fish fishing all around offshore rock piles. Most anglers are satisfied at this point. I personally try and take it a step further. Is there a "spot on a spot" that consistently produces cast after cast ? Is there a specific cast angle I need to make time and time again ? Is there a specific lure that will catch more fish at this spot ? Thinking like this can make a good day an amazing day. Every day I try and find a pattern within a pattern. I keep a very detailed fishing log and have done so now for close to 20 years. A lot of anglers think this is not necessary and shrug at the though of doing so. I am sure everyone's results would be different, I suppose. It has over time enabled me to find seasonal patterns, lake patterns, water temperature patterns, lure patterns, etc, for the waters I fish. When these patterns intersect, " a pattern within a pattern", I have found the fishing to be the best. During spring on lake x, fishing lure x, when the water temp is x, when the conditions are x, produces for me year after year after year. Yes sure I am fishing memory but I am fishing patterns as well. I fish quality spots from "memory" to find patterns that produce year after year. I like to "fine tune" a pattern. Attention to detail is extremely important.
It really clicked for me when I got on some quality fish on my favorite lake in 2012. It was spring and I was catching big largemouth and big smallmouth on a black jig and pig. I was targeting a very specific spot, a 50 ft section of clay bank. At first the fishing was not fast and furious. I was consistently catching fish on the black jig and pig, good ones too 3 and 4 lb largemouth. Then just by chance one of them spit up a hand full of crayfish, they were orange and brown. The fishing slowed a bit. I decided to tie on a brown and orang jig with a crayfish piece of pork.
On the first cast I caught a 7-6 largemouth. I started catching fish on nearly every cast, big fish to ( for Maine) for nearly an hour. Once the bite slowed a bit I tried to copy the crayfish pattern with a crankbait. Within the first couple casts I caught another big largemouth, a 6-8. Naturally I decided I didn't need to move from this spot. I stayed there all day. If I went 5 casts with the jig and didn't get bit I would switch to the crank bait and do the same with the crankbait. Most of the time I would catch a fish on the initial cast after switching baits. I stayed on these fish, in the same 50 yard section all day. By the end of the day I had landed my best 5 fish limit, 7-6,7-1,6-8,6-3,5-4 for 32 lbs 6 oz. My biggest 5 smallies weighed 18 lbs 2 oz that day as well. It was incredibly good fishing. In my mind I found a pattern within a pattern on a spot on a spot. A clay bank in the spring was the initial pattern, then fine tuned to it had to be an orange and brown jig or an crayfish colored crankbait. Of course the next day I brought my friend there. He is a diehard black on black jig fisherman. Once I had landed 9 fish to his 1 he asked me for a brown and orange jig. It simply had to be a brown and orange jig or you weren't going to get bit.
Since then I have returned to the specific spot, during a specific time of year and water temperature, fishing those same lures and the results have been consistent every year. Athough I have never have had a 5 fish bag of 32 lb 6 oz since then I have had 30 lbs 6 oz and 29 lbs 15 oz. In 2014 when I had 30 lbs 6 oz I probably should have broken my best 5 bag but I lost a couple very large fish. That day though I did land 10 largemouth over 5 lbs. Every year consistently that pattern on that spot produces giant northern largemouth and big smallies. It has to be those specific lures or you aren't going to get many bites.
My point to this long rant is that when you can combine a good fishing spot or better yet a spot on a spot with a fine tuned pattern the fishing can be amazing. That is what I try for every single time on the water. The fishing log I spoke of before enables me year after year to return to specific lakes where specific patterns set up every year. It gives me a very good idea of what the fish are doing well before I get to the launch.
I guess to answer the original question to this thread is I fish a combination of spots, and patterns given the previous fishing experience to establish a fine tuned pattern.
End rant.
