The best rates for River Jelly are when fishing in the freshwater pond in [[Ginger_Island#Island_West|Ginger Island West]] using a [[Training Rod]]. Under these conditions, there are only 2 possible catches: River Jelly and [[Snake Skull]]. Only if the farmer fails the random check to catch both of these will the farmer get [[Trash]].<ref name="catch_distribution"/>

The best rates for River Jelly are when fishing in the freshwater pond in [[Ginger Island#Island West|Ginger Island West]] using a [[Training Rod]]. Under these conditions, there are only 2 possible catches: River Jelly and [[Snake Skull]], as all of the fish that can be caught have difficulty greater than or equal to 50. Only if the farmer fails the random check to catch both of these will the farmer get [[Trash]].

However, unlike when catching regular fish or other items, the random value used to determine whether a River Jelly is successfully caught is predetermined. This value only changes when catching a [[Cave Jelly|Cave]], River, or [[Sea Jelly]], or any [[Fish]]. It is not changed by catching Algae, Trash, or any other catchable items.<ref name="jelly_RNG"/> Because of this, after catching Trash using the Training Rod, it is necessary to catch a regular fish before another River Jelly. This can easily be done by switching to any [[Fishing Pole]] other than the Training Rod, and continuing to fish until an actual fish is caught, at which point the farmer should switch back to the Training Rod.

Ordinarily, 10% of possible random values result in a successful River Jelly catch. Each level of [[Luck#Luck_Buffs|Luck Buff]] increases the chance of a successful catch by 5%.<ref name="jelly_rate"/> So with +8 Luck, 50% of random values will result in a successful catch. This allows for longer streaks without failing a Sea Jelly catch, although you will still unavoidably catch some Snake Skulls or Seaweed, depending on the area chosen.

(It is possible to achieve similar rates when fishing in either [[The_Desert|Desert]] pond, although you will catch [[Green Algae]] or [[Pyramid Decal]], depending on your choice of pond, rather than Snake Skulls as your alternative drop. Fishing in the Desert does not require use of the Training Rod if done after dark or in the lower pond, as there are no fish to be caught, however this also means that there is no convenient way to refresh the Jelly's random value once it changes to a failing value.)

It is also possible to achieve similar rates when fishing in either [[The Desert|Desert]] pond, although either [[Green Algae]] or [[Pyramid Decal]] instead of Snake Skulls will be the alternative drop. Fishing in the Desert does not require use of the Training Rod if done after 8 pm or in the lower pond, as there are no fish to be caught. However, this also means that there is no convenient way to refresh the Jelly's random value once it changes to a failing value.
