What are the optimal levels for fishmeal and methionine in juvenile shrimp diets?
A correct balance of fishmeal and dietary methionine has a critical effect on Pacific white shrimp growth performance and economic efficiency.

Effect of dietary additives supplemented in inert microdiets for Pacific white shrimp
Dietary, health-promoting additives may address some larviculture issues and support the downstream production of high-quality L. vannamei.

Water exchange and dietary methionine requirement for juvenile Pacific white shrimp
This study evaluated if reduced water exchange in an intensive, outdoor culture system could spare dietary Met (Met+Cys) required for maximum growth performance of juvenile Pacific white shrimp.

Effect of dietary methionine on Pacific white shrimp juveniles
This study tested five diets formulated with increasing levels of methionine (Met) and Met + cysteine (Cys) and their effect on growth performance of juvenile Pacific white shrimp stocked at 50, 75 or 100 animals/m2 in a green water system.

Methionine hydroxy analog supplements low-fishmeal shrimp diets
In a study, the authors evaluated the performance of juvenile white shrimp grown at high density and fed diets with varying levels of methionine. Trends toward improvements in feed intake were observed for diets with reduced fishmeal and HMTBa supplementation.

Methionine supplement form affects feed leaching, but not shrimp growth
A study compared the effects of two forms of methionine supplemented at different levels in feeds for Pacific white shrimp. Test diets containing methionine bound in soy protein had less leaching of methionine than the diets containing crystalline methionine.

Methionine requirements estimated for white shrimp
Research on the methionine requirement for white shrimp showed a diet requirement of 0.45 percent using a protein-bound form of methionine.

Methionine-, sulfur-containing amino acids: Limiting nutrients in commercial formulations?
Trials indicated that in order to determine methionine and TSAA requirements for shrimp, methionine must be added to research feeds in either a chelated or covalently bound form.
