Couple of things I pass on when shopping, frozen or fresh...
But probably fine
Feeding Only Pigs in a Pig–Tilapia–Shrimp System
If you want to raise pigs, tilapia, and shrimp but feed only the pigs, you can still use the integrated system’s biological benefits — but you must manage the fish side carefully so it doesn’t rely on pig feed. How the system works
In a pig–tilapia–shrimp integrated farm, pig manure and pen washwater are released into the pond.
This Feeds bacteria that break down organic matter into ammonia and nitrites
Fertilizes phytoplankton (algae) which feed zooplankton
Provides organic matter for benthic feeders and shrimp

This natural food chain reduces the need for fish feed, but it does not eliminate it — tilapia still need 30–50% of their feed from commercial sources in the first 90 days

Feeding only pigs
If you feed only the pigs:- Pig manure becomes the main nutrient source for the pond’s plankton and invertebrates, which support tilapia and shrimp
- You can still stock tilapia and shrimp at recommended densities (e.g., ~2,000 tilapia/ha and ~5,000 shrimp/ha in polyculture)
- The fish will grow on natural food plus some supplemental feed if needed, but you won’t be buying fish feed — only pig feed.
