A Fish Farmer’S Role In Sustainable Aquaculture: An Overview Of Philippine Aquaculture, Janice A. Ragaza, Jonni Fay C. Teves Dec 2014

A Fish Farmer’S Role In Sustainable Aquaculture: An Overview Of Philippine Aquaculture, Janice A. Ragaza, Jonni Fay C. Teves

Biology Faculty Publications

The expansion of Philippine aquaculture is essential to addressing poverty and food insecurity in the midst of a seemingly irreversible decline in national capture fisheries. Concomitant with its rise, however, are compounding environmental problems caused by climate change, lackluster governance and irresponsible farming practices. It is equally important to ensure aquaculture sustainability so that fish demand from a rapidly growing population is continually met and that fish farmers’ socioeconomic well-being is secured. As such, programs have been developed that aim to enjoin the government and private sectors with fishing communities to realize this goal.


Phylogenetic Analysis Of Algal Symbionts Associated With Four North American Amphibian Egg Masses, Eunsoo Kim, Yuan Lin, Ryan R. Kerney, Lili Blumenberg, Cory Bishop Nov 2014

Phylogenetic Analysis Of Algal Symbionts Associated With Four North American Amphibian Egg Masses, Eunsoo Kim, Yuan Lin, Ryan R. Kerney, Lili Blumenberg, Cory Bishop

Biology Faculty Publications

Egg masses of the yellow-spotted salamander Ambystoma maculatum form an association with the green alga “Oophila amblystomatis” (Lambert ex Wille), which, in addition to growing within individual egg capsules, has recently been reported to invade embryonic tissues and cells. The binomial O. amblystomatis refers to the algae that occur in A. maculatum egg capsules, but it is unknown whether this population of symbionts constitutes one or several different algal taxa. Moreover, it is unknown whether egg masses across the geographic range of A. maculatum, or other amphibians, associate with one or multiple algal taxa. To address these questions, we conducted ...


Hydrolyzed Tuna Meat By-Product Supplement For Juvenile Red Sea Bream, Pagrus Major, And Its Effect On Growth, Enzyme Activity, Plasma Parameters, And Apparent Nutrient Digestibility, Janice A. Ragaza, Roger Edward P. Mamauag, Shunsuke Koshio, Manabu Ishikawa, Saichiro Yokoyama Nov 2014

Hydrolyzed Tuna Meat By-Product Supplement For Juvenile Red Sea Bream, Pagrus Major, And Its Effect On Growth, Enzyme Activity, Plasma Parameters, And Apparent Nutrient Digestibility, Janice A. Ragaza, Roger Edward P. Mamauag, Shunsuke Koshio, Manabu Ishikawa, Saichiro Yokoyama

Biology Faculty Publications

A growth experiment was conducted on juvenile red sea bream, Pagrus major to investigate the effect of the inclusion in fish diets, of tuna meat by-product hydrolysate which was processed through enzymatic hydrolysis using a commercially available enzyme, derived from Bacillus subtilis. Six experimental diets were formulated in the experiment. Three diets contained 50, 150 and 250 g/kg of TPM-H (tuna meat by-product hydrolysate), and two diets with the unprocessed TPM (tuna meat by-product) at an inclusion level of 50 and 250 g/kg. A control diet was formulated without any addition of the test ingredients. Treatment diets were ...


Schooling Increases Risk Exposure For Fish Navigating Past Artificial Barriers, Bertrand H. Lemasson, James W. Haefner, Mark D. Bowen Sep 2014

Schooling Increases Risk Exposure For Fish Navigating Past Artificial Barriers, Bertrand H. Lemasson, James W. Haefner, Mark D. Bowen

Biology Faculty Publications

Artificial barriers have become ubiquitous features in freshwater ecosystems and they can significantly impact a region's biodiversity. Assessing the risk faced by fish forced to navigate their way around artificial barriers is largely based on assays of individual swimming behavior. However, social interactions can significantly influence fish movement patterns and alter their risk exposure. Using an experimental flume, we assessed the effects of social interactions on the amount of time required for juvenile palmetto bass (Morone chrysops × M. saxatilis) to navigate downstream past an artificial barrier. Fish were released either individually or in groups into the flume using flow ...


Effects Of Replacing Fishmeal With Squash Seed Meal (Cucurbita Maxima) On Performance Of Juvenile Nile Tilapia (Oreochromis Niloticus), Janice A. Ragaza, Jonni Fay C. Teves, Marie Noelle Fernandez Apr 2014

Effects Of Replacing Fishmeal With Squash Seed Meal (Cucurbita Maxima) On Performance Of Juvenile Nile Tilapia (Oreochromis Niloticus), Janice A. Ragaza, Jonni Fay C. Teves, Marie Noelle Fernandez

Biology Faculty Publications

The effects of replacing fishmeal with squash (Cucurbita maxima) seed meal (SSM) on Oreochromis niloticus juveniles were investigated on a 30-day feeding trial. Triplicate groups of ten (10) O. niloticus juveniles (2.54±0.949 g) stocked in polyethylene tanks received iso-nitrogenous diets with SSM inclusion levels of 0%, 5%, 10%, 15% and 20%. Fish fed 5% SSM inclusion level showed the highest average weight gain (202.25±36.26%) and specific growth rate (3.76±0.42%) among the fish fed SSM-containing diets. However, there were no significant differences between the average weight gain and specific growth rate of ...
