“…Para juvenis (6 a 8 g de peso inicial) de yellowtail flounder (Limanda ferruginea), carnívoro endêmico das águas geladas da América do Norte, o maior ganho de peso foi obtido com alimentação 2 ou 4 vezes/dia, em comparação a uma única alimentação diária ou, ainda, uma alimentação a cada dois dias (Dwyer et al, 2002). Tendência de aumento do ganho de peso foi registrada para juvenis de linguado (Paralichthys olivaceus) (peso inicial de 3,5 g) com o aumento da freqüên-cia alimentar de 1 a cada dois dias para 1, 2 ou 3 alimentações diárias durante 40 dias (Lee et al, 2000a (Sampath, 1984). Estudos evidenciam que o consumo de grandes quantidades de alimento em curtos intervalos de tempo diminui a eficiência digestiva (Windell et al, 1978;Bergot & Breque, 1983;Henken et al, 1985).…”

“…A influência da freqüência alimentar sobre o desenvolvimento de juvenis tem sido estudada em várias espécies (Tsevis et al, 1992;Wang et al, 1998;Lee et al, 2000a;Lee et al, 2000b;Dwyer et al, 2002), sendo normalmente observado aumento no ganho de peso quando juvenis são alimentados mais de uma vez ao dia. Entretanto, Carneiro & Mikos (2005) não detectaram diferença significativa no ganho de peso, na taxa de crescimento específico e na conversão alimentar entre grupos de juvenis de jundiá com peso médio inicial de 1,88 g quando alimentados 1, 2, 3 ou 4 vezes ao dia, durante 65 dias, em viveiros com temperatura média de água de 25,2 ± 1,3 o C. Desse modo, objetivou-se investigar o efeito de diferentes freqüências alimentares sobre o desempenho de juvenis de jundiá (peso médio inicial 7,47 g) alimentados em viveiros de terra durante 120 dias.…”

RESUMO -Com objetivo de avaliar a influência da freqüência alimentar no ganho de peso, na taxa de crescimento específico, na conversão alimentar e na sobrevivência de juvenis de jundiá, 12 grupos de 280 peixes (7,47 ± 1,73 g) foram estocados em viveiros de terra (2 peixes/m 2 ). Uma dieta comercial extrusada, com 42% de PB, foi fornecida até a aparente saciedade em quatro regimes de arraçoamento: 1, 2, 3 e 4 vezes ao dia, em triplicata, durante 120 dias (maio a setembro de Effect of feeding frequency on performance of jundiá juvenilesABSTRACT -The influence of feeding frequency was evaluated on weight gain, specific growth rate, feed conversion and survival of jundiá juveniles. Twelve groups of 280 fish (7.47 ± 1.73 g) were each stocked in twelve ponds (2 fish/m 2 ) and fed to apparent satiety an extruded commercial feed containing 42% CP In four feeding schedules: 1, 2, 3 and 4 times a day, in triplicate, for 120 days (May to September, 2003). Average weight gain was recorded by sampling 10% of the total fish/ pond approximately every forty days. Water quality was monitored throughout the experimental period by measuring temperature, dissolved oxygen, pH, turbidity, ammonia, alkalinity and hardness which were 18.1 ± 0.1ºC, 7.9 ± 0.2 mg/L, 8.0 ± 0.8, 109 ± 29 cm, 0.5 mg/L, 46 mg/L CaCO 3 , and 40 mg/L CaCO 3 , respectively. Fish weight gain and specific growth rate increased as feeding frequency increased. Juveniles fed four times a day showed significantly higher weight gain and specific growth rate than fish fed just once a day. Feed conversion did not differ significantly among feeding frequencies, however survival was significantly higher for the groups fed three times a day when compared to the ones fed only once a day. Therefore, jundiá juveniles weighing from 8 to 45 g should be fed at least twice a day, when raised in earthen ponds at an average water temperature of 18°C.

“…Diketahui pula dengan strategi pemuasaan pada ikan akan meningkatkan efisiensi pakan yang jauh lebih baik dengan laju pertumbuhan yang sama dengan ikan yang diberi makan secara periodik setiap hari (Yuwono et al, 2005). Namun asumsi tersebut belum dapat dijadikan tolok ukur untuk memacu pertumbuhan, karena frekuensi pemberian pakan juga akan mempengaruhi 609 laju cerna dan pertumbuhan ikan (Lee et al, 2000;Jackson et al, 2007). Setiap ikan memiliki bentuk dan ukuran lambung yang berbeda-beda.…”

A study on the effect of feeding frequency on coral trout culture Plectropomus leopardus was conducted in floating net cages. The aim of this study was to determine an optimum feeding frequency for better growth rate and feed conversion ratio. Keywords: feeding frequency, floating net cage, Coral Trout ABSTRAKStudi frekuensi pemberian pakan ikan kerapu sunu telah dilakukan dalam keramba jaring apung. Tujuan penelitian adalah untuk menentukan frekuensi pemberian pakan yang optimum terhadap pertumbuhan dan konversi pakan ikan kerapu sunu. Penelitian dibagi 2 tahap berdasarkan ukuran berat tubuh ikan, yaitu ukuran 24-100 g (tahap 1) dan 100-150 g (tahap 2). Untuk tahap satu dilakukan 4 perlakuan, yang diuji adalah perlakuan frekuensi pemberian pakan 4 kali sehari (4/1), 3 kali sehari (3/1), 2 kali sehari (2/1) dan 1 kali sehari (1/1). Untuk tahap dua dilakukan dengan perlakuan 3 kali sehari (3/1), 2 kali sehari (2/1), 1 kali sehari (1/1), dan 1 kali /2 hari (1/2), dimana setiap perlakuan dilakukan 3 kali ulangan. Ikan diberi pakan berupa pelet sampai kenyang pada setiap pemberian pakan. Hasil percobaan menunjukkan bahwa dalam tahap satu dan dua, perlakuan pemberian pakan 2 kali sehari menunjukkan pertumbuhan yang tinggi dan konversi pakan yang rendah berbeda nyata dengan perlakuan lainnya (P<0,05). Sintasan pada tahap satu pada perlakuan (4/1), (3/1), (2/1) lebih tinggi daripada (1/1) (P<0,05), sedangkan sintasan antara perlakuan pada tahap 2 tidak berbeda nyata (P>0,05). Frekuensi pemberian pakan yang terbaik untuk species ini adalah 2 kali sehari untuk berat tubuh dari 24 sampai 150 g. Kata kunci: frekuensi pemberian pakan, karamba jaring apung, kerapu sunu I. PENDAHULUANKeberhasilan perbenihan dalam memproduksi benih kerapu sunu (Plectropomus leopardus) secara massal telah mendorong berkembangnya teknologi pembesaran ikan kerapu sunu di keramba jaring apung (KJA).

“…Growth is affected by the amount of food consumed and the efficiency of assimilation (Buurma and Diana, 1994). Making food available at an appropriate rate can increase feed efficiency (Lee et al, 2000). Study of Carlos (1988) on bighead carp fry found that the highest feeding rate of 30% resulted in better growth.…”

“…The influence of feeding frequency on growth has been examined in several species including hybrid sunfish (Wang, et al, 1998), Japanese flounder (Lee et al, 2000), tilapia (Riche, et al, 2004), Australian snapper (Tucker, et al, 2006), tambaqui (Silva, et al, 2007), and cuneate drum (Wang, et al, 2007). Feeding frequency and ration size play a determinant role in regulating feed intake, growth and waste outputs of fish (Silva, et al, 2007;and Wang, et al, 2007).…”

Abstract. This study aimed to develop a suitable feeding program for the Asian sea bass, lates calcarifer fingerlings under supersaline condition by testing different feeding rates (FR) and feeding frequencies (FF). Three feeding rates namely; 1%, 2% and 4% and three feeding frequencies 1X, 2X and 4X were used in the study. Results showed that growth after 60 days parameters gave the highest values with 4% and 4X. FCR increased with increasing FR, while better FCR and PER was achieved with increasing FF. Survival rates in all the feeding rates and frequencies were almost 100%. Significant relationship was recorded between growth, FCR and PER and feeding rates, but not with FF. No significant relationship in both FR and FF with survival rate. Interaction effect of FR and FF was exhibited in all the growth parameters and FCR. All the water quality values obtained were within the safe limits for rearing the Asian sea bass fingerlings.
