“…Indeed, previous experiments had shown that this value is close to the extreme resistance of snails submitted to constant hunger (group 6 in the present paper) when they are reared in water (von Brand et al, 1957;Vianey-Liaud, 1984, 1990Vianey-Liaud & Lancastre, 1986). …”

Mature Biomphalaria glabrata, submitted to four weeks of varied starvation times (0, 1, 3, 5, 6 & 7 d.week-1, were thereafter refed during four weeks. The different intermittent starvation times had no significant effect on snails survival. As weekly starvation increased, the rate of change in body weight and fecundity decreased. In snails fed one or two d.week -1, the rate of change in body weight was negative, while fecundity remained at a low level. Continuous hunger stopped oviposition.Starvation had no further effect on body growth after the first week of refeeding; however, its effect on fecundity remained significant over the two first weeks.

“…Therefore it can be concluded that the low concentration of haemocyanin in the blood of the slug during starvation may be due to the catabolism of haemocyanin, showing a significant decrease of copper and protein concentrations, suggesting that the proteins may have been used up as an energy source and the copper released has been transported and accumulated in the hepatopancreas. The low concentration of haemocyanin in the blood may be sufficient to meet the oxygen requirements of the starved slugs as evidenced by the low oxygen utilization of Australorbis glabratus during starvation (von Brand et al 1957).…”

The copper and protein concentrations in the blood and in the purified haemoeyanin of active and starved slugs were detennined.During starvation there is a marked decrease in the haemocyanin concentration in the blood. How. ever the copper protein ratio of the purified haemocyanin of the active and starved slugs remained unchanged suggesting that baemocyanin remains unaltered during starvation.There is a significant increase of hepatopancreatic copper upon starvation. The hepatopancreas is suggested to store copper during starvation. The results are discussed in the light of the previous works on crustaceans and molluscs,

“…[3] During estivation, snails do not eat and water loss occurs. [4] Oxygen consumption is also reduced. [5] Pulmonate snails, including the planorbids, retract into their shells during estivation, but they do not form a protective epiphragm or mucus membrane to close the opening of the shell.…”

“…[5] Pulmonate snails, including the planorbids, retract into their shells during estivation, but they do not form a protective epiphragm or mucus membrane to close the opening of the shell. [3,4] To understand how snails survive estivation, it is important to know how this condition affects the snails physiologically and biochemically. Studies of the digestive gland-gonad complex (DGG) and the whole bodies of snails provide good indicators of changes in the lipid content of snails as a function of diet, parasitism, starvation, and estivation.…”

High performance thin layer chromatography (HPTLC) was used to determine neutral lipids and phospholipids in Biomphalaria glabrata (NMRI strain) and Helisoma trivolvis (Colorado strain) snails during estivation and starvation. Control snails were maintained on a diet of Romaine lettuce leaves. HPTLC analyses showed a significant (ANOVA, P , 0.05) decrease in triacylglycerols in estivated and starved snails compared to the controls and a significant increase in steryl esters in estivated and starved snails compared to the controls.
