Full Cycle
Product Application Guidelines: Plastic-Lined and Concrete Ponds
01 — Overview
What this protocol is for
Complete product application reference for plastic-lined and concrete ponds from preparation through harvest. The grow-out dosage schedule is identical to the earthen pond protocol. Differences are in pond preparation only: no soil drying, use soft tools for liner cleaning, and the optional high-organic-matter pre-treatment step is not applicable. For plastic lined ponds with plastic lining on the sides but an earth bottom, follow the earth bottom pond protocol.
Primary Objective
Provide a complete reference for product application in plastic-lined and concrete-bottom pond systems, from preparation through harvest.
02 — Indications
When to use this protocol
Plastic-lined and concrete ponds, all species
Important Notes
- !
Do not use lime, dolomite, or zeolite with Blue Aqua system.
- !
No antibiotics, disinfectants during culture, pesticides, or herbicides.
- !
No water exchange. Top up only.
- !
For plastic lined ponds with plastic lining on the sides but an earth bottom, follow the earth bottom pond protocol.
03 — Procedure
Step-by-step instructions
- 1
Drain and clean liner
Drain completely. Remove sludge using soft tools. Remove debris and biofilm from liner surfaces and walls.
- 2
Optional: post-disease chlorination
If pond had a disease event in the previous cycle: fill to maximum level. Wait 2 or more days for pathogen spores or eggs to hatch. Apply 10 ppm free chlorine (bacterial) or 30 ppm (viral). Leave 3 days. Aerate on Day 4 to evaporate chlorine.
- 3
Incoming water disinfection
Disinfect incoming water with AlphaSep 1 to 2 ppm (10 to 20 kg per hectare). Leave for 1 day.
- 4
Mineral pre-treatment
Apply MinGro 10 kg per hectare (1 ppm) for 2 to 3 days with aerators running.
- 5
Phytoplankton check before stocking
Confirm Secchi disk reads 50 cm before stocking.
- 6
Day 1: Artemia supplement
Apply Artemia at 1 can per 200,000 PLs.
- 7
- 8
Day 4: SoilGro
Apply SoilGro. Following day: apply molasses.
- 9
Regular dosage schedule from 1 week post-stocking through harvest
Identical to earthen pond schedule. See Parameters table. AlphaGuard*L Plus applied daily via feed throughout.
