“…This hormone concentration is at least ten times lower than that employed in other studies (Lam 1980, Nacario 1983, Lam & Sharma 1985, Reddy & Lam 1992, De Jesus et al 1998, Lam et al 2005. Furthermore, the administration protocol had a positive effect on fish growth and no negative effects on fish survival, while it induced a burst in growth of w30% in both T 3 -and T 2 -treated fish (Table 2).…”

Recent studies in our laboratory have shown that in some teleosts, 3,5-di-iodothyronine (T 2 or 3,5-T 2 ) is as bioactive as 3,5,3 0 -tri-iodothyronine (T 3 ) and that its effects are in part mediated by a TRb1 (THRB) isoform that contains a 9-amino acid insert in its ligand-binding domain (long TRb1 (L-TRb1)), whereas T 3 binds preferentially to a short TRb1 (S-TRb1) isoform that lacks this insert. To further understand the functional relevance of T 2 bioactivity and its mechanism of action, we used in vivo and ex vivo (organotypic liver cultures) approaches and analyzed whether T 3 and T 2 differentially regulate the S-TRb1 and L-TRb1s during a physiological demand such as growth. In vivo, T 3 and T 2 treatment induced body weight gain in tilapia. The expression of L-TRb1 and S-TRb1 was specifically regulated by T 2 and T 3 respectively both in vivo and ex vivo. The TR antagonist 1-850 effectively blocked thyroid hormone-dependent gene expression; however, T 3 or T 2 reversed 1-850 effects only on S-TRb1 or L-TRb1 expression, respectively. Together, our results support the notion that both T 3 and T 2 participate in the growth process; however, their effects are mediated by different, specific TRb1 isoforms.

“…Low water salinity in post-larvae fish farming has less effect on the growth and survival than high salinities, as observed by Specker et al (1999) for Paralichthys dentatus. Several freshwater fish species show maximum growth and survival rates when reared in slightly salinized water, up to 5‰, such as Cyprinus carpio (Lam and Sharma, 1985), Odontethes hatcheri (Tsuzuki et al, 2000), Heterobranchus longifilis (Fashina-Bombata and Busari, 2003), whereas others like Ictalurus punctatus show reduced fingerling growth (Baldisserotto, 2002). In salinities above 1.7‰ reduced growth of pintado may have been caused by the high energy consumption to maintain inverse osmoregulation, i.e., eliminating salt and retaining water.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito de água levemente salinizada sobre a larvicultura intensiva do tambaqui, matrinxã, apaiari e piau, durante os dias iniciais de alimentação. As larvas foram mantidas em água artificialmente salinizada, em concentrações de 0 (água doce) a 14 g L -1 de NaCl (intervalo de 2,0 g L -1 ), e foram alimentadas com duas porções diárias de náuplios de Artemia, de acordo com protocolo para cada espécie, em delineamento inteiramente casualizado, com três repetições. Larvas de tambaqui, matrinxã e apaiari podem ser cultivadas em até 2 g L -1 de concentração salina, sem prejuízos ao crescimento e à sobrevivência. Larvas de piau foram mais tolerantes e suportaram até 4 g L -1 de concentração salina. Acima disto, a mortalidade dos peixes aumentou e chegou a 100% à concentração de 6 g L -1 (matrinxã e apaiari) e de 10 g L -1 (tambaqui). A salinização da água a 2 g L -1 proporcionou maior taxa de sobrevivência a larvas de matrinxã e maior crescimento a larvas de tambaqui, apaiari e piau. Estas duas últimas espécies apresentaram melhor crescimento com a maior quantidade de náuplios. Água salinizada a 2 g L -1 é benéfica para as espécies estudadas, pois otimiza o potencial de crescimento das larvas e o uso de náuplios de Artemia como alimento vivo. Termos para indexação: Astronotus ocellatus, Brycon amazonicus, Colossoma macropomum, Leporinus macrocephalus, alimento vivo, náuplios de Artemia. Slightly saline water increases the larviculture efficiency of freshwater Neotropical fishAbstract -The objective of this work was to evaluate the effect of slightly saline water in an intensive larviculture of tambaqui, matrinxã, apaiari, and piau, during the initial days of active feeding. Larvae were reared in artificial saline water, at concentrations from 0 (freshwater) to 14 g L -1 NaCl (at a 2.0 g L -1 ), and fed with two portions of Artemia nauplii, following a specific protocol for each species, in a completely randomized design, with 3 replicates. Tambaqui, matrinxã and apaiari larvae can be reared at saline concentrations till 2 g L -1 without impairing growth and survival. Piau larvae were more tolerant and endured saline water until 4 g L -1 . At saline concentrations above that, fish mortality increased and reached 100% at 6 g L -1 , for matrinxã and apaiari, and at 10 g L -1, for tambaqui. Saline water at 2 g L -1 provided a higher survival for matrinxã, and higher growth for tambaqui, apaiari and piau. These last two species showed a better growth performance with the highest quantity of nauplii. Slightly saline water at 2 g L -1 is beneficial to these studied species, as it optimizes larval growth potential and the use of Artemia nauplii as live food.
