Fishing Theory

Introduction

This page is dedicated to theories about fishing. This includes Fishing Skill, Fish, Lures, Player Skills, and Catching.

This page was created out of reason for better understand of fishing. The wiki pages on fishing were full of scattered information and lacking in mechanics of fishing. This page is to help clear up things and help people understand fishing better. Although this is not full proof information, it is a beginning for a greater understanding.

To avoid misconceptions and false information, please add the facts only. The bottom of this page contains a data section which the categorizing of fish cycles should go. Data that also proves or disproves information should be posted in the data section below the fish tables.

Fishing Skill

Fishing skill is learned from the school of body and is level 1 at the time. Overtime a player's fishing skill increases. This increase may take weeks/months of fishing before it will increase, but when this occurs it's usually in multiple increases at a time. The exact amounts needed are unknown.

Higher levels of fishing skill are required to catch rare fish.

Fish

Grouping and Rarity

Teppy announced there is 49 different species of fish. Seven of these are the common fish. Which leaves 42 fish that are not.

The common group includes: Abdju, Carp, Catfish, Chromis, Perch, Phagrus, Tilapia. For most lures, you will catch some of these types fish throughout the day.

Uncommon fish require Speed, Fishing Skill, and possibly Perception.

Speed fish are the second most common fish you will catch. If you do not have sufficient speed, you will see the message "You almost caught a unusual fish, but were not quick enough." The requirement is not sharp: if you have almost enough speed, you will have some chance of catching this type of fish.

Skill fish are the next in rarity. If you have insufficient fishing skill, you see "You almost caught an odd fish, but you were too late recognizing the bite." You may also need speed to catch some of these fish. This type of fish is impossible to catch with fly fishing 1.

The third fish requirement yields the message "You almost caught a strange fish, but this rod was just too clumsy." This is currently believed to indicate that higher perception is required.

Last thing to note is the difficulty of catching vary among fish. Observations against two speed fish showed at 25 speed: 16 deben pancake loach and 22 deben tigerfish both were unsuccessful. 1/3 Rate on tigerfish and 0% on pancake. Observation against the same two with 28 speed showed 100% success.

Cycles

All fish except the common 7 have a daily cycle (when in season). The cycle for a given fish species peaks at the same time of game day for all lures, with the fish size reduced on either side of this time. Fish and lures that give very large peak sizes are therefore available for much longer periods of time than those peaking at small sizes.

For example, in Year 3 Akhet II, River Crab peaked at 40+ deben sizes in a certain location, and so were available for 16 game hours per day. Sea Urchin peaking at 9 debens was only available for 2 game hours on a single lure in Akhet II, but much longer and on more lures in Akhet I with higher peak.

Lures

Each fish has a "best lure" that gives the largest size of that type of fish when used. Lures other than the best give reduced fish sizes.

Uncommon fish have peak sizes that change each game month, and may be zero indicating that the species cannot be caught that month. These peaks can be up to about 40 debens in that fish's best month, while common fish peak at about 9 debens (16 with pyramid bonus).

Player Skills

Speed is a confirmed variable in catching fish. Certain uncommon fish have a high speed that is required. Common fish require at least zero or greater, if negative, you will always receive quickness messages. Tests against (Tigerfish) resulted in 25% chance with 4 speed, and 100% at 27 speed.

Perception increases the chance of success against fish who cause the clumbsy message. Tests against (Ivory Knifefish & Spoonfish) resulted in a 1/6th chance with 18 perception, and 50% at 34 perception. However Rainbow Cod also give this message, and the same chance of catching (~30%) was observed for both perception 7 and perception 28.

Fly Fishing skill enables you to catch "odd fish", with many types of fish impossible to catch with skill 1.

Catching The Fish

Fishing has different variables that are used throughout a cast of a lure. These include Fishing Skill, Speed, and Perception, but may include others.

1) There is a chance of making a successful cast based on your Fly Fishing skill. This is roughly 40% at skill 1, 90% at skill 6, and 100% at skill 9. Failure of this check leads to the message "You didn't catch anything."

2) A species of fish is determined from those available to be caught with that lure at that time of day. This is usually (but not always) the species that has the largest sizes available. If there are no fish available you will see the message "No fish bit."

3) The species may have requirements such as skill, speed, or perception. These are checked against your current stats and skill and an appropriate message given if the check fails.

4) If all of the above checks pass, you will see "Caught X Deben Fish."

Size of Fish

Each time an uncommon fish is selected in step 2, the size of future catches of that species drops for that avatar. For common fish, the size drops by more but is recovered faster. If the size drops below 1 deben (before pyramid bonus) then that species is removed from the pool of available fish until its size recovers to 1 or more.

Experimental results appear to show that the rate of recovery is 1/10th of the drop per successful cast (i.e. any result but "You didn't catch anything"). Uncommon fish appear to drop by 0.92 for each catch, while common fish drop by about 7.

Data

This section is dedicated to both mapping the fish groups and cycles, and data that proves or disproves information about fishing.

Fish Cycles

This chart shows collected data on peak fish sizes and their best lures (out of the 44 I have available). The sizes likely apply only to my camp, but the times and lures should be more widely useful. - Tamutnefret

Rare Fish Info

This data was plotted from on the cooking graph. This is just a few of the possible combinations, as it seems most fish have more then one combo. If you wish to check these or for others just open the cooking graph. What you are looking at is if the three fish would intersect with a parallel line.

To spawn a rare fish the two combo fish must be active at the same time. This will spawn the rare fish as long as they are both active. Once one of the fish finishes its cycle, the rare fish goes too.

Sea Urchin and Ayu are both active this month (Year 3 Akhet II). Has anyone caught an Oxyrynchus? Also, what exactly is a "rare fish"? The previous description on this page was not at all useful as some fish would be considered rare in some months and not in others. For example any of Rainbow Cod, Sea Urchin, or White Oniontail could be considered "rare fish" this month. - Tamutnefret

Some additional information could be useful here. Given we meet the criteria for a "rare" fish spawn (stats, location, a suitable combo, etc...), what sort of lure should we use to find these spawns? One of the lures that catches one the "combo fish"? A lure that catches both types of the "combo fish"? Or a different lure altogether? -Myn 09:52, 11 May 2011 (EST)

The Fishing Map

The Fishing Web

The fish web is a stripped down copy of the Food Graph(thx to tefnut for the work). This data shows the connections between fish and why lures spawn rare fish. After more review of my own data and Tamutnefret post of the lures time table, I have mapped out the current month.

This is a picture of the connections for the current month of (Akhet II Year 3)

When looking at the graph you can see how the fish are grouped. The seven common are the first tier of fish. Then you have "spawn" fish such as Rivercrab, Tigerfish, Ayu, Queen Lionfish, Nile Mackerel The next group is the fish such as Spiny Dogfish, Bay Lobster. Medusafish, White Oniontale. Then finally is the rares such as Yellowfin Snapper and Ribbonfish. The rares spawn when an two fish overlap. Each of the connections to a rare has one lure. This month both rares have two lures and extended times.

Thanks to everyone who contributed to the data! And thanks to Luck for finding this information :)
