“…This species contributes significantly to commercial fishing in Argentina (Cotrina, 1989;Cotrina & Raimondo, 1997) and is considered of great potential for aquaculture diversification (Pajuelo & Lorenzo, 1996;Maragoudaki et al, 1999;Suzer et al, 2007;Schuchardt et al, 2008). Even though several studies on development of red porgy have been carried out, as far as we know, there are no previous studies on larval condition of this species.…”

Morphometrical and histological techniques were employed to characterize Pagrus pagrus larvae nutritional condition. Larvae were reared in laboratory under controlled conditions with the main objective of testing whether these methodologies allowed finding differences between larvae from different feeding treatments. Once yolk was consumed (three days after hatching) larvae were assigned to a feeding treatment: starved during the whole experiment; delayed feeding, starved during three days; fed during the entire experiment. Algae (Nannochloropsis oculata) and rotifers (Brachionus plicatilis) were provided to larvae for feed treatments. Larvae were fixed daily; for morphometrical purposes in 5% formaldehyde solution, and in Bouin for histological sections. Results herein obtained showed that both methodologies are sensitive enough to distinguish larvae characterized by different nutritional condition states obtained from the feeding treatments. Consequently, these methodologies could be employed in wild red porgy larvae in order to asses their nutritional condition. These techniques could also be employed to check larval quality obtained with aquaculture purposes to estimate the effects of changes in rearing protocols or kind of food supply and thus, to guaranty a higher survival of early developmental stages of reared larvae.Con el objeto de determinar si las técnicas morfométricas e histológicas permiten diferenciar larvas en estado de inanición de las sometidas a tratamientos de alimentación, ejemplares de Pagrus pagrus fueron criados en laboratorio bajo condiciones controladas. Una vez que el vitelo fue consumido (tres días luego de la eclosión) las larvas fueron sometidas a diferentes tratamientos de alimentación: completamente privadas de alimento, privadas de alimento durante tres días y luego alimentadas, y alimentadas durante todo el experimento. Algas (Nannochloropsis oculata) y rotíferos (Brachionus plicatilis) fueron proporcionados a las larvas de los tratamientos de alimentación. Diariamente se fijaron ejemplares de los tres tratamientos en formol 5% para estudios morfométricos y en Bouin para estudios histológicos. Los resultados obtenidos dan evidencias de que las metodologías presentadas son suficientemente sensibles para determinar diferencias en la condición de larvas sometidas a los tratamientos de alimentación. Por lo tanto, podrían ser empleadas para determinar la condición nutricional de las larvas de besugo recolectadas en el mar. Por otra parte, éstas metodologías podrían ser empleadas para determinar la calidad de larvas producidas en acuicultura y evaluar los efectos de modificaciones introducidas en los protocolos de crianza o en el tipo de alimento suministrado con el objeto de mejorar la supervivencia de los estadios tempranos de desarrollo.

PENDAHULUANAnguilla bicolor bicolor merupakan salah satu jenis ikan sidat yang banyak dibudidayakan di Indonesia dan termasuk ke dalam jenis ikan karnivora yang memiliki pertumbuhan yang lambat. Pertumbuhan ikan sidat dalam satu siklus pemeliharaan dari benih ukuran glass eel (0,09-0,12 g) mencapai ukuran konsumsi (250 g) membutuhkan waktu sembilan bulan sampai dua tahun bahkan beberapa di antaranya terhenti pada ukuran 2-3 g. ABSTRACTThe study was aimed to determine the optimum dietary protein level and energy protein ratio which can optimize growth performance of the eel A. bicolor bicolor on nursery phase. Four treatments and three replications were applied in this study. The treatments were P1, containing 37.66% protein with energy protein ratio 14.75 kcal GE/g (37.66%; 14.75 kcal GE/g), treatment P2 (41.30%; 13.51 kcal GE/g), treatment P3 (45.38%; 12.27 kcal GE/g), and treatment P4 (49.60%; 11.31 kcal GE/g). Eels used for this study were 6.5±0.3 g in average body weight. Eels were reared in a series of aquaria with dimension 90×40×40 cm 3 and filled with 100 L of fresh water. Total weight of eel stocked in aquarium were 400 g. Eels were fed until satiated twice a day at 8 am and 4 pm for 60 days. The result showed that different protein level and energy protein ratio was significantly affected growth performance (feed consumption, specific growth rate, feed efficiency, protein retention, and lipid retention), protein and fat of whole body eels at confident limit of 5%. In contrary, there was no significant different on the survival rate, hepatosomatic index, ash content, and nitrogen free extract of the body eel. The optimal growth performance was reached by dietary protein level and energy protein ratio of 45.38%; 12.27 kcal GE/g and 49.60%; 11.31 kcal GE/g. Keywords: Anguilla bicolor bicolor, energy protein ratio, feed, growth performance, protein ABSTRAKPenelitian ini bertujuan menentukan kadar protein dan rasio energi protein optimum yang dapat meningkatkan kinerja pertumbuhan ikan sidat A. bicolor bicolor fase pendederan. Empat macam perlakuan dan tiga ulangan digunakan dalam penelitian ini. Perlakuan tersebut adalah P1 yang mengandung protein 37,66%; dengan rasio energi protein 14,75 kkal GE/g (37,66%; 14,75 kkal GE/g), perlakuan P2 (41,30%; 13,51 kkal GE/g), perlakuan P3 (45,38%; 12,27 kkal GE/g) dan perlakuan P4 (49,60%; 11,31 kkal GE/g). Bobot rata-rata ikan sidat yang digunakan adalah 6,5±0,3 g. Ikan sidat dipelihara dalam akuarium berukuran 90×40×40 cm 3 dengan volume air 100 L. Total bobot ikan yang digunakan dalam setiap akuarium adalah 400 g. Ikan sidat diberi pakan sekenyangnya dengan frekuensi dua kali sehari yaitu pukul 08.00 dan pukul 16.00 WIB selama 60 hari. Hasil menunjukkan bahwa pemberian kadar protein dan rasio energi protein pakan berbeda, memberikan pengaruh nyata (P<0,05) terhadap kinerja pertumbuhan (jumlah konsumsi pakan, laju pertumbuhan spesifik, efisiensi pakan, retensi protein, retensi lemak), protein tubuh dan lemak tubuh, tetapi tidak berpengaruh nyata (P>0,05) terhadap t...

Regarding S. hasta, there is no available study that determined the absolute dietary lipid requirement in this species; however, Mozanzadeh et al [93] recommended to include lipids between 15% and 20% taking into account the results from a study about the effects of dietary carbohydrate to lipid ratios, as illustrated in the next section.…”

Silvery-black porgy (Sparidentex hasta) is recognized as one of the most promising fish species for aquaculture diversification in the Persian Gulf and the Oman Sea regions. In this regard, S. hasta has received considerable attention, and nutritional studies focused on establishing the nutritional requirements for improving diet formulation have been conducted during recent years. Considering the results from different dose-response nutritional studies on macronutrient requirements conducted in this species, it can be concluded that diets containing ca. 48% crude protein, 15% crude lipid, 15% carbohydrates and 20 KJ g −1 gross energy are recommended for on-growing S. hasta juveniles. In addition, the optimum essential amino acid profile for this species (expressed as g 16 g N −1 ), should be approximately arginine 5.3, lysine 6.0, threonine 5.2, histidine 2.5, isoleucine 4.6, leucine 5.4, methionine + cysteine 4.0 (in a diet containing 0.6 cysteine), phenylalanine + tyrosine 5.6 (in a diet containing 1.9 tyrosine), tryptophan 1.0 and valine 4.6. Moreover, the optimum dietary n-3 long chain polyunsaturated fatty acids and soybean lecithin are recommended to be 0.8% and 6%, respectively. The maximum replacement of fish meal with soy protein is recommended to be between 16.5% and 27.3%. In addition, different vegetal oil sources are also recommended for partial and almost complete replacement of fish oil in diets. Although the nutritional requirements in terms of macronutrients have been established under laboratory conditions, the analysis of the available literature indicate that future studies need to be conducted using a more holistic approach under intensive farming conditions in which different nutrients or additives need to be tested under different rearing conditions for refining nutrient requirements in this species.
