“…Kasim (7) found variable behavioral patterns in different carps at different salinities, where common carp showed higher tolerance to salinity than that of rohu and mirigal. Kliambi and Zdinak (8) while working with grass carp fingerlings recorded 71 -90% mortality in 24 hours under 15‰ salinity. As reported by Nugon (9) juveniles of O. aureus, O. niloticus and Florida red tilapia exhibited good survival (> 81%) in salinity regimes up to 20‰, with moderate survival of O. aureus (54%) and Florida red tilapia (33%) at 35‰ salinity.…”

An experiment was carried out to find the salinity tolerance capability and growth performance of Climbing Perch, Anabas testudineus (Bloch, 1795). Anabas testudineus commonly cultured fish in Bangladesh was reared in laboratory conditions at different salinities of 0, 3, 6, 9, 12, 15, 18 and 21‰ for 60 days. Hundred per cent survivals were detected at 0, 3, 6 and 9‰ salinity while 100% mortality was recorded at 18 and 21‰ salinity. Various responses to threat and feeding were observed among the fish in different treatments. Lowest feed conversion ratio was found in the control group while the highest was detected at 15‰ salinity. On the other hand, decreasing trend of specific growth and average growth rate were observed in A. testudineus fingerlings from 0 to 15‰ salinity. Significantly higher specific growth rate and average growth rate were detected in A. testudineus fingerlings reared at 0 -6‰ salinity (p < 0.05). The present study suggests that Climbing Perch fingerlings can be reared at fresh water growth rates in coastal water with salinity up to 6‰.

“…Decreasing growth rates with increasing salinity, as shown for Clarias larvae in the present study, appear to be characteristic of freshwater stenohaline fish and it has been postulated that this is due to increasing maintenance requirements at higher salinities (BREIT 1979;KILAMBI 1980). Associated physiological effects observed with increasing salinity are increased food intake but poor conversion efficiency, and reduced oxygen consumption and weight loss (ARUNACHALAM and REDDY 1979;MACEINA and SHIREMAN 1979;KILAMBI 1980;KILAMBI and ZDINAK 1980;MACEINA et al 1980;VON OERTZEN 1985). The decreasing condition factor of C. guriepznus larvae observed at higher salinities in the present study probably are a reflection of such effects.…”

Growth and survival of replicate batches of African sharptooth catfish (Clarias gariepinus) larvae were monitored in 0, 2.5, 5.0, 7.5 and 10 ppt salinity. No significant differences in mortality or growth rate were evident between 0 and 5 ppt salinity. At 7.5 ppt mortality rate was higher and larval growth rate declined in comparison to the lower salinities. At 10 ppt all larvae died within 48 hours. The condition factor of the larvae similar benveen 0-2.5 ppt and displayed a declining trend between 2.5-7.5 ppt.Osmoconcenuation of blood plasma of C. ga*iepinus in fresh water was 280 2 20 mOsm/kg which is equivalent to 9.5 ppt salinity. It was concluded that 0-2.5 ppt is the optimal sclinity range for larval rearing and that short-term exposure to higher salinities (2.5-7.5 ppt) could be effective in the treatment of ectoparasitic diseases.

Zwischen 0 und 5 ' %o konnten keine signifikanten Unterschiede in der Mortalitat und im Wachstum festgestellt werden. Bei 7, 5O%o war die Mortalitat erhoht, und die Wachstumsrate nahm im Vergleich zu den niedrigeren Salzgehalten ab. Bei 1 0 L starben alle Larven innerhalb von 48 Stunden. Der Konditionsfaktor der Larven war bei 0 und 2,5 vergleichbar. Zwischen 2,5-7,5 %o hatte er eine abnehmende Tendenz. Die Osmokonzentration des Blutplasmas von C. gariepinus im SiiRwasser betragt 280+20 mOsm/kg. Dies entspricht einem Salzgehalt von 9,5' %o. Aus den Er ebnissen wurde geschlossen, daR 0-23 L der optimale Salinitatsbereich fur die Larvenaufzucht ist u n i d d eine Kurzzeitexposition mit hoheren Salinitaten (2,s-7,5 %) eine Moglichkeit zur Behandlung von ektoparasitiren Krankheiten darstellt.

“…It would be of particular interest to compare adaptation to saline conditions in primary versus secondary freshwater species . Tolerance to saline conditions has been investigated in primary species such as members of the families Cyprinidae (Matthews & Hill, 1977 ;Kilambi & Zdinak, 1980 ;Vigg, 1982 ;Kraiem & Pattee, 1988 ;Frain, 1987), Catostomidae (Wilkes & McMahon, 1986a ;1986b ;Walker et al, 1989), and Cen-149 trarchidae (Peterson, 1988) as well as secondary freshwater families such as the Fundulidae (Duff & Fleming, 1972 ;Ahokas & Duerr, 1975), Poeciliidae (Al-Dahan & Bhatti, 1977 ;Chervinski, 1984), Gasterosteidae (Nelson, 1968) and Cichlidae (cf.

A dye process in a textile plant in southern Kentucky (USA) produces large quantities of saline wastewater which eventually enter Lake Cumberland via a municipal sewage treatment plant on Lily Creek . The impact of hypersaline conditions on two fish species native to the Cumberland River drainage system, redbelly dace (Phoxinus erythrogaster) and northern studfish (Fundulus catenatus), was assessed . These species were subjected to salinities of 0, 4, and 10% after which routine oxygen consumption values were determined . Significant correlations of salinity with oxygen consumption were demonstrated for both species with P. erythrogaster showing greater overall impact of salinity on metabolic rate .
