Comparison of techniques for stabilizing hemoglobins of rainbow trout (Salmo gairdneri) during frozen storage

1. The stability of hemoglobin of rainbow trout under frozen conditions in oxyform, carboxyform, and cyanometform was examined.2. Carboxyhemoglobin retained its original electrophoretic banding pattern after 14 days of frozen storage, whereas oxyform and cyanometform hemoglobins did not.3. Banding patterns changed in some samples in all treatment groups after 21 days of storage.

Vitamin E and selenium interrelations in the diet of Atlantic salmon (Salmo salar): Gross, histological and biochemical deficiency signs

Either simultaneous or separate dietary deficiencies of vitamin E and selenium in Atlantic salmon during first 4 weeks of feeding caused twice the mortality shown in fish fed both supplemental vitamin E (0.5 IU/g dry diet) and selenium (0.1 µg/g). Subsequent dietary repletion with both vitamin E and selenium significantly reduced mortality during the following 2 weeks. Larger salmon (0.9 g initial

Feeding algae to fish

Aquarium-held bigmouth buffalo Ictiobus cyprinellus (Valenciennes) were fed the blue-green alga Spirulina platensis (Nordstedt) at a daily rate of 29 g dry weight/kg body weight for 28 days. Daily growth was 14 g/kg body weight, and food conversion was 2.0. Tilapia aurea (Steindachner) also was fed this blue-green alga; growth and food conversion were similar to those found for bigmouth buffalo.
