The family hosts a convention for scientists in their family garden. Actually this happens every single day! It’s a lot of work so everyone takes a turn pulling weeds, applying fertilizer and gathering the harvest. Fishing is a necessary task to supply fertilizer for the plants, and the family’s other scientist, Manzano, is at the shore working on that. If you want an inexpensive but highly effective fertilizer for your plants, have your experienced fisherman use perfect grapes or apples (both cheap produce and easily grown) to pull in tons of jelly fish and minnows. A perfect specimen of either of these is an outstanding fertilizer. Both fish are common with plentiful spawners, and can be caught in massive quantity. This frees up your higher value produce and fish for cooking and sales. Your sim will also have more time to enjoy life, since every moment away from the garden won’t need to be spent with rod and reel in hand.
