“…These results are in agreement with those mentioned by Bardach et al (1972) for Java and Nile tilapia, although no details of the experimental conditions regarding fish size and water characteristics are given. The same general figure for the daily food requirements for S. mossambicus P. is given by Pandian & Ragharaman (1972) and Mathavan, Kanandan & Pandian (1976). Also, a similar relationship between feeding rate and fish of the same size used in the present experiment is recommended by Jauncey & Ross (1982), based on the experimental work of Macintosh (1982) and Macintosh & De Silva (1982) for S. mossambicus P. and 5. niloticus L. and for water temperature of 28°C.…”

Abstract. Four populations of 42 specimens (mean initial b.wt 64·02–65·29g) of Tilapia aureus (Steindachner), were reared for 15 weeks in 600‐1‐capacily cylindrical plastic tunks, from a closed circulated system, al four feeding levels (1,2,3 and 4% of b.wt daily). A feeding level of 2% of b.wt daily seems to be the best, taking into consideration biological (specific growth rale, food conversion rate, protein efficiency ratio, values of total plasma lipids, cholesterol and triglyceridcs. haematocrit, proximate carcass analyses, body weight‐length relationships) and economical (feed cost) criteria. Also, it is concluded that for T. aureus the use of closed or semiclosed circulated systems could he us satisfactory as other forms of intensive production systems.

The number of herbivores in populations of ectothermic vertebrates decreases with increasing latitude. At higher latitudes, fish consuming plant matter are exclusively omnivorous. We assess whether omnivorous fish readily shift to herbivory or whether animal prey is typically preferred. We address temperature as the key factor causing their absence at higher latitudes and discuss the potential poleward dispersion caused by climate changes. A controlled experiment illustrates that rudd (Scardinius erythrophthalmus) readily utilize plant matter at water temperatures above 20 °C and avoid its consumption below 20 °C. Field data support these results, showing that plant matter dominates rudd diets during the summer and is absent during the spring. Utilizing cellulose requires the enzyme cellulase, which is produced by microorganisms growing at temperatures of 15–42 °C. Water temperatures at higher latitudes do not reach 15 °C year-round; at our latitude of 50°N~150 days/year. Hence, the species richness of omnivorous fish decreases dramatically above 55° latitude. Our results provide support for the hypothesis that strict herbivorous specialists have developed only in the tropics. Temperatures below 15 °C, even for a short time period, inactivate cellulase and cause diet limitations for omnivorous fish. However, we may expect increases in herbivory at higher latitudes caused by climate change.
