“…As demonstrated in the present study with severum larvae, the photoperiod did not influence the survival rate of Nile tilapia (El-Sayed and Kawanna, 2004;Veras et al, 2013c), silver catfish (Rhamdia quelen) (Piaia et al, 1999), tambaqui (Colossoma macropomum) juveniles (Mendonça et al, 2012), burbot (Lota lota) juveniles (Trejchel et al, 2013), or Pyrrhulina brevis (Veras et al, 2016). In these cases, the manipulation of the photoperiod probably did not alter the homeostasis of these species and did not change in studies with fingerlings of Persian sturgeon (Acipenser persicus) (Zolfaghari et al, 2011) and Nile tilapia (Veras et al, 2013c).…”

“…In these studies, the high mortality in dark environments is attributed to a reduced ability of larvae to find food (Reynalte-Tataje et al, 2002;Shan et al, 2008). In addition, for species that utilize vision to catch their food, exposure and movement of prey are key stimuli for the detection and recognition of food (ReynalteTataje et al, 2002;Veras et al, 2013c;Veras et al, 2016).…”

“…On the other hand, long and continuous photoperiods have been shown to stimulate the growth of numerous species of fish as in studies of Nile tilapia larvae (El-Sayed and Kawanna, 2004), croaker miiuy (Miichthys miiuy) (Shan et al, 2008), and Pyrrhulina brevis (Veras et al, 2016); Nile tilapia fingerlings (Rad et al, 2006;Bezerra et al, 2008;Cruz and Brown, 2009;Veras et al, 2013a), Persian sturgeon (Acipenser persicus) (Zolfaghari et al, 2011), tambaqui (Mendonça et al, 2012) and red sea bream juveniles (Biswas et al, 2005), striped knifejaw (Oplengnathus fasciatus) (Biswas et al, 2008) and croaker miiuy (Shan et al, 2008).…”

“…Já o baixo valor de uniformidade do peso pode ser explicado pela variação de desenvolvimento entre machos e fêmeas dentro do lote. Essa variação no crescimento entre os sexos também foi relatada quando larvas de Pyrrhulina brevis foram expostas à diferentes fotoperíodos e duas frequências de alimentação (4 ou 2 vezes ao dia) (VeRAs et al, 2014).

RESUMO: A fitoterapia vem sendo utilizada em criação de peixes a fim de promover estabilidade no ambiente de cultivo e na profilaxia de doenças, contribuindo para melhoria do bem-estar animal. Dentre os fitoterápicos, a canela (Cinnamon zeylanicum) possui atividade antioxidante, antiinflamatória, antifúngica e antiparasitária, além de efeito imunoestimulante. O objetivo do trabalho foi avaliar os efeitos do extrato aquoso de canela sobre o desempenho produtivo de larvas do peixe ornamental amazônico Pyrrhulina brevis. Foram avaliadas cinco concentrações de extrato aquoso (0; 0,25; 0,50; 0,75 e 1,0 g/L) em 4 repetições, durante 20 dias. A utilização de 1,0g/L de extrato de Cinnamon zeylanicum favorece o desempenho produtivo das larvas, com melhores resultados para comprimento total final, taxa de crescimento específico para comprimento e promove 100% de sobrevivência ao lote (P<0,05). Este é o primeiro relato da eficácia do uso de extrato aquoso de canela como promotor de crescimento na larvicultura de peixes.Palavras-chave: fitoterapia, peixe ornamental, sanidade. AQUEOUS CINNAMON EXTRACT AS A GROWTH PROMOTER FOR LARVAE OF THE ORNAMENTAL AMAZON FISH Pyrrhulina brevisABSTRACT: Phytotherapy has been used in fish farming to promote stability in the rearing environment and for the prophylaxis of diseases, improving animal well-being. Among phytotherapeutic agents, cinnamon (Cinnamon zeylanicum) exhibits antioxidant, anti-inflammatory, antifungal and antiparasitic activity, in addition to immunostimulatory effects. The objective of this study was to evaluate the effect of an aqueous cinnamon extract on the productive performance of larvae of the ornamental Amazon fish Pyrrhulina brevis. Five concentrations of the aqueous extract (0, 0.25, 0.5, 0.75 and 1.0 g/L) were evaluated in four replicates over a period of 20 days. The use of 1.0 g/L of Cinnamon zeylanicum extract favored larval performance, improving final total length and the specific growth rate in length and promoting 100% survival of the batch (P<0.05). This is the first study demonstrating the efficacy of the use of aqueous cinnamon extract as a growth promoter in fish larviculture.

ABSTRAKIkan gabus Channa striata merupakan salah satu komoditas ikan air tawar yang memiliki nilai ekonomis tinggi. Kendala dalam pengembangan budidaya ikan gabus adalah tingginya tingkat kematian pada stadia pemeliharaan larva. Tingginya kematian pada stadia larva karena kecukupan jumlah pakan dan nutrisi pakan awal yang tidak optimum. Tujuan percobaan adalah menentukan frekuensi pemberian Moina sp. yang tepat sebagai pakan awal pada pemeliharaan larva ikan gabus pada sistem air hijau (dengan menambahkan Chlorella sp.). Penelitian dirancang dengan rancangan acak lengkap. Perlakuan yang diberikan adalah frekuensi pemberian Moina sp. per hari sebagai pakan awal: A. enam kali tanpa pemberian Chlorella sp. (kontrol), B. enam kali + Chlorella sp., C. empat kali + Chlorella sp., dan D. dua kali + Chlorella sp. Hasil penelitian menunjukkan pemberian pakan awal dari jenis Moina sp. pada pemeliharan larva ikan gabus pada sistem air hijau dengan frekuensi pemberian dua, empat, dan enam kali dalam sehari memberikan performa sintasan (93,42%-94,29%) dan pertumbuhan tidak berbeda secara nyata (P>0,05). Frekuensi pemberian Moina sp. sebanyak dua kali sehari merupakan perlakuan yang efektif untuk sintasan dan pertumbuhan larva ikan gabus pada pemeliharaan dengan sistem air hijau.KATA KUNCI: larva ikan gabus; frekuensi pemberian pakan; Moina sp.; sintasan; pertumbuhan; air hijau ABSTRACT: Effects of different feeding frequencies using Moina sp. as an initial food on growth and survival of snakehead Channa striata larvae reared in green water system. By: Adang Saputra, Dedi Jusadi, Muhammad Agus Suprayudi, Eddy Supriyono, and Mas Tri Djoko SunarnoSnakehead fish Channa striata is one of the highly-valued freshwater fish commodity. However, its aquaculture development is hampered by a high mortality during larval stage rearing. This high mortality is suspected to be caused by insufficient quantity and quality of food. The purpose of this study was to determine the appropriate feeding frequency using Moina sp. as an initial food for snakehead fish larvae reared in a green water system (Chlorella sp.). A completely randomized design was arranged for this experiment where the treatments consisted of different feeding frequencies of Moina sp. given to the larvae as follows: A) six times a day without the addition of Chlorella sp. (control); B) six times a day with the addition of Chlorella sp.; C) four times a day with the addition of Chlorella sp.; and D) two times a day with the addition of Chlorella sp. The results of the experiment showed that the survival rate (93.42%-94.29%) and growth of the larvae reared in the green water system with were not significantly different (P>0.05). However, this study suggested that feeding frequency of two times per day was sufficient to support an optimum growth and survival of snakehead larvae reared in a green water system.
