Survival, growth and osmolality of greenlip abalone Haliotis laevigata (Donovan 1808) when exposed to different ionic profiles of inland saline water

Abstract

Two experiments over 21 days were conducted to assess the e¡ect of di¡erent ionic pro¢les (mainly K 1 ) of inland saline water (ISW) on the survival, growth, osmoregulation and moisture content of juvenile greenlip abalone Haliotis laevigata. In experiment I, the juveniles were cultured in ¢ve di¡erent water types: ocean water (OW) as a control, inland saline water (ISW or ISW K 1 0 ), ISW forti¢ed with 33%, 66% and 100% K 1 as in OW (ISW K 1 33 , ISW K 1 66 and ISW K 1 100 respectively). In experiment II, ¢ve di¡erent culture media, 100% OW(control), 75% OW mixed with 25% ISW (ISW 25 ), 50% OW mixed with 50% ISW (ISW 50 ), 25% OW mixed with 75% ISW (ISW 75 ) and 100% ISW (ISW or ISW 100 ), were tested. Within 21 days, all of the abalone in ISW (ISW K 1 0 and ISW 100 ; Na 1 /K 1 ratio of 111 L À 1 ) died compared with 100% survival in OW. One-hundred per cent K 1 forti¢cation of ISW increased the speci¢c growth rate (SGR) and serum osmolality of the surviving juveniles. The 96 h acute LC 50 value was between ISW 50 and ISW 75 . The increased proportion of ISW in OW resulted in signi¢cantly (Po0.05) lower survival, SGR and serum osmolality of juveniles. The moisture content of the juveniles was not in£uenced by any water type. The results suggested that abalone cannot survive in raw ISW, but survival can increase when it is forti-¢ed with K 1 and ionic ratios of ISW are brought closer to OW by mixing it with OW. Furthermore, abalone survival is in£uenced by other ions in ISW besides K 1 .

Hatchery seed production of giant freshwater prawn,Macrobrachium rosenbergiiusing inland ground saline water in India

“…Rahman, Jain, Reddy, Kumar and Raju (2005), Ingram et al (2002) and Pragnell and Fotedar (2006) have also reported total mortality of shrimps when they were reared in ISW. Similarly, cases of fish and mollusc mortality on transfer from SW to ISW of equivalent salinities have been documented (Fielder et al 2001;Partridge & Creeper 2004;Doroudi, Fielder, Allan & Webster 2006;Fotedar, Harries & Savage 2008).…”

Survival and Growth of Tiger Shrimp (Penaeus monodon) in Inland Saline Water Supplemented with Potassium

“…Low level of potassium in inland saline ground water has been reported by several researchers [3,5,8,15,21]. Deficiency of potassium in ISW has been responsible to cause mortality in fishes [5,6,22], crustaceans [1,3] and molluscs [23]. High mortality rate at 15 g/L and the low rate at 5 g/L in PD-ISW indicate that the mortality rate depends on the ratio of potassium with that of salinity in ISW as ISW:CSW potassium ratios were assessed higher (0.21:1.00) at salinity 5 g/L, in comparison to salinities of 10 g/L (0.12:1.00) and 15 g/L (0.08:1.00) in PD-ISW (Table 1), which were similar to the findings of Fielder et al [5].…”

Productivity ofSargassum linearifoliumin potassium fortified inland saline water under laboratory conditions

“…In addition, the Sargassum can be used as biochemical compounds for agriculture (Ara, Ehteshamul-Haque, Sultana, Ghaffar & Qasim, 1997), cattle food or fertiliser (Huisman, 2000), human food (Bast, 2014;Wang, Huang, Xiong, Xie & Li, 2010), or using the extraction for medicine (Hur et al, 2008;Thuy et al, 2015;Wang et al, 2010), and to clean water discharged from aquaculture (Partridge, 2008;Troell, R€ onnb€ ack, Halling, Kautsky & Buschmann, 1999;Van Khoi & Fotedar, 2011), and being a biosorbent for heavy metals (Davis, Volesky & Vieira, 2000). Therefore, integrated farming between Sargassum and shrimp, or seabream, or seabream and abalone or seabream and sea urchin can result in higher aquaculture yields and income (Cruz-Su arez et al, 2010;Jin & Dong, 2003;Kitadai & Kadowaki, 2007;Neori et al, 1996Neori et al, , 2004, and some species are already practiced in ISW in Australia (Collins, Russell, Walls & Hoang, 2005;Fotedar, Harries & Savage, 2008;Prangnell & Fotedar, 2005). Sargassum is also good food for sea urchin (Winberg, Goosh & Tapsell, 2009).…”
