Dietary carbohydrate and food processing affect the digestive physiology of Piaractus mesopotamicus
(2016-08-01)
The responses of the digestive physiology of juvenile pacu to different diet processing were studied. Fish were fed with isoproteic diets with 260 g kg−1 of crude protein (CP) containing different levels of carbohydrate ...
Species specific in vitro protein digestion (pH-stat) for fish: method development and application for juvenile rainbow trout (Oncorhynchus mykiss), cobia (Rachycentron canadum), and Nile tilapia (Oreochromis niloticus).
(Amsterdam, 2014-04-20)
Aqua feed manufacture requires flexible formulations and effective methods to screen suitable feed ingredients. In vitro digestion may assist in the characterization and quality control of protein in feedstuffs for fish ...
Digestive enzyme activities during pejerrey (Odontesthes bonariensis) ontogeny
(Elsevier Science, 2020-07)
The first step for assessing and refining the nutritional requirements during the larval and early juvenile stages of a fish is the study of the ontogeny of digestive system functionality. The combination of these studies ...
Ontogeny of the digestive system and the profile of proteases in larvae of cachara (Pseudoplatystoma reticulatum Siluriformes: Pimelodidae) and its hybrid (Pseudoplatystoma corruscans × Pseudoplatystoma reticulatum)
(2021-09-01)
The development of the digestive system and digestive proteases was studied in cachara (Pseudoplatystoma reticulatum) and its hybrid (P. reticulatum × Pseudoplatystoma corruscans) during the first 25 days after fertilization. ...
From fish-processing waste to feed additives for crayfish
(Wiley Blackwell Publishing, Inc, 2019-01)
This research studied the in vitro compatibility of Cherax quadricarinatus digestive proteases and crude enzyme extracts recovered from fish-processing waste to evaluate their potential use as feed additives to increase ...
Maize distillers dried grains with solubles alter dietary digestibility and improve intestine health of pacu, Piaractus mesopotamicus juveniles
(Cambridge Univ Press, 2021-06-28)
Two trials were conducted to evaluate the effects of soyabean meal replacement by maize distillers dried grains with solubles (DDGS) in diets for pacu juveniles. Five diets were formulated with 0, 100, 200, 300 and 400 g ...
Phytase effects on protein and phosphorus bioavailability in fish diets
(WAGENINGEN ACAD PUBL, 2016)
Screening and characterization of sex-specific DNA fragments in the freshwater fish matrinch, Brycon amazonicus (Teleostei: Characiformes: Characidae)
(Springer, 2012-10-01)
The matrinch Brycon amazonicus, a commercially important freshwater fish resource, has no heteromorphic sex chromosomes so far described. In the present study, we performed a screening of sex-associated DNA markers in this ...
A new approach to fishery waste revalorization to enhance Nile tilapia (Oreochromis niloticus) digestion process
(Wiley Blackwell Publishing, Inc, 2017-12)
The main goal of this research was to analyse in vitro compatibility of Nile tilapia (Oreochromis niloticus) digestive proteinases and enzymes recovered from species comprising fishery waste as Pleoticus muelleri, Artemesia ...
