An Initial Investigation Replacing Fish Meal With A Commercial Fermented Soybean Meal Product In The Diets Of Juvenile Rainbow Trout, Michael E. Barnes, Michael L. Brown, Kurt A. Rosen, Jason R. Sewell

Natural Resource Management Faculty Publications

The inclusion of PepSoyGen (PSG), a commercially-available fermented soybean meal product, was evaluated with juvenile rainbow trout, Oncorhynchus mykiss in an initial 70-day feeding trial, with a supplemental trial involving a subset of the experimental diets continuing for an additional 40 d. Six diets containing 0%, 10%, 20%, 30%, 40%, or 50% PSG, with the PSG directly replacing fish meal, were used in the first trial. There were no significant differences in weight gain or feed conversion ratio between the fish meal-based control diet and diets containing up to 30% PSG. However, weight gain was significantly reduced and feed conversion …

Juvenile Rainbow Trout Responses To Diets Containing Distillers Dried Grain With Solubles, Phytase, And Amino Acid Supplements, Michael E. Barnes, Michael L. Brown, Kurt A. Rosentrater

Natural Resource Management Faculty Publications

Distillers dried grain with solubles (DDGS) was evaluated in juvenile Shasta-strain rainbow trout Oncorhynchus mykiss diets during a 36-day feeding trial. Two experimental diets containing either 10% or 20% DDGS with supplemented amino acids (lysine, methionine, isoleucine, and histidine) and phytase were compared to a fish meal-only control diet. Tanks of trout receiving diets containing either concentration of DDGS weighed significantly less at the end of the trial and had significantly poorer feed conversion ratios than tanks of fish being fed the fish mealonly control. There was no significant difference in individual fish length, weight, condition factor, or any fish …

Ramphotyphlops Braminus (Brahminy Blindsnake): Predation, Louis A. Somma

Papers in Herpetology

Ramphotyphlops braminus currently has the most widespread, near worldwide, nonindigenous distribution of any snake. In Florida, USA, R. braminus is rapidly expanding its distribution.

The stomach contents of a necropsied Dasypus novemcinctus (nine-banded armadillo) found on the premises of the Florida Department of Agriculture and Consumer Services in Gaisesville in March 2011 included an intact adult R. braminus. Dasypus novemcinctus is nonindigenous in Florida. It has a primarily insectivorous diet but occasionally preys upon small vertebrates, including reptiles. This is the first record of R. braminus in the diet of D. novemcinctus.

Notes On The Diet Of The Malay Civet (Viverra Tangalunga) And Other Civets In Logged And Unlogged Lowland Dipterocarp Rain Forests In Sabah, Borneo, Christina P. Colon, John B. Sugau

Publications and Research

Civet diets were examined in a logged and unlogged Bornean rain forest. Malay civets (Viverra tangalunga) consumed invertebrates, fruit, rodents, insectivores, birds, snakes and lizards, and appear to show preference for centipedes and scorpions. Other civet species consumed fruit, such as figs, Connarus sp. and Annona sp., particularly in the unlogged forest, but also consumed invertebrates and vertebrates. Reduced fruit consumption observed in the logged forest may be due to lower availability and may be offset by increased consumption of invertebrates. The increased overlap in diet between Malay civets and other civets in disturbed areas may lead to …

Patterns Of Seasonal Variation In Diet, Abundance, And Movement Of The Scarlet Macaw (Ara Macao) In Southern Belize, Mark Stephen Mcreynolds

Antioch University Dissertations & Theses

This study was conducted in 2008 and 2009 to determine if Scarlet Macaws (Ara macao), in subtropical southern Belize, Central America, are seasonal and elevational migrants and if their movement is influenced by seasonally abundant food. Reports from southern Belize indicated strongly seasonal sightings of macaws (N ≈ 200) in two separate areas of considerable difference in elevation. I monitored plant phenology plots (2 m x 500 m) in low (N = 6) and high (N = 6) elevation areas for a year to compare fruit abundance with macaw sightings in point counts on the plots and nearby. My point …
