Inorganic Phosphorus Supplementation in Diets for Farmed Shrimp: Performance and Digestibility of Juvenile Litopenaeus vannamei Fed Monosodium Phosphate, Monoammonium Phosphate, Magnesium Phosphate, and Monocalcium Phosphate

Aquaculture Research, Volume 2024, Issue 1, 2024.
Inorganic phosphates have been used in shrimp feeds to meet phosphorus (P) needs, which may be quantitatively affected by the dietary content of P and other minerals and digestibility. In the present study, performance and digestibility were determined simultaneously in juvenile shrimp (Litopenaeus vannamei) during the grow‐out period (4–23 g ind wt ...

PROCESSOS HIDRO-EROSIVOS EM SOLOS DEGRADADOS EM RELEVO DE BAIXA DECLIVIDADE (HYDRO-EROSIVE PROCESSES IN DEGRADED SOILS ON GENTLE SLOPE) [PDF]

, 2016
Muitas pesquisas conferem maior peso na alta declividade do terreno como fator decisivo no processo hidro-erosivo. Porém, foi avaliado que baixas declividades (~4º) já são suficientes para se iniciar o escoamento superficial.
