ABSTRACT Colossoma macropomum, known locally as tambaqui, is the native fish most farmed in Brazil, however, technological advances are needed to reach efficient production rates. Modulating growth factors, such as growth hormone, may be associated with improved growth rate and feed efficiency. The use of exogenous hormone for fish rearing is prohibited in Brazil, yet the experimental use of bovine hormone can be useful in research aimed at understanding how to stimulate endogenous growth hormones in fish. Therefore, the present study had the strict objective of understanding the effects of growth hormone on the physiology and zootechnical parameters of C. macropomum under experimental conditions. The animals were intraperitoneally injected every fifteen days with 1, 10 and 100 μg g-1 of bGH using 0.9% NaCl saline as diluent. The 10 and 100 μg g-1 bolus had a positive effect on the performance indexes of C. macropomum: weight gain (g), growing length (cm), daily weight gain (g), feed conversion and specific growth rate (% per day). The bGH promoted a greater increase in length than in mass, which caused a reduction in condition factor of the individuals receiving a bolus of 10 and 100 μg g-1. Furthermore, bGH caused no changes in glucose levels, cortisol, hematological parameters, plasma levels of Na+ and K+, and activity of gill’s H+-ATPase and Na+, K+-ATPase, at least during the experimental period considered in the present study.

The experiment was carried out to study the effects of different doses of pig dung on the growth rate of Catlacatla during the summer season. Rate of application of pig dung doses were 10000 kgha-1 yr-1 ,15000 kgha-1 yr-1 , 20000 kgha-1 yr-1 and 25000 kgha-1 yr-1 . The experiment was carried out in a Completely Randomized Block Design. There were four replicates for each treatment where pig dung was applied at 10000 kgha-1 yr-1 (T1), 15000 kgha-1 yr-1 (T2), 20000 kgha-1 yr-1 (T3) and 25000 kgha-1 yr-1 (T4) and control. The control pond did not receive pig dung. After 10 days of application of pig dung, Catla was stocked at the rate of 8,000 nos./ha in the fish ponds. Sampling was done at 15 days interval to study the growth rate and health status of the fishes. At the end of 3 months period, the fishes were harvested, and the performance of growth, survival and total production was recorded viz. 72.92±6.41g.The results of the study clearly indicated that in the indirect integration system of pig-fish farming, where fresh pig dung contains 0.61% nitrogen, 0.50% phosphate-phosphorus (PO4-P), the dung load of 20000 kgha-1 yr-1 is optimum for satisfactory growth of catla, which yield an average production of 5354.00 kgha-1 yr-1 .

Short Period

The production of chemical fertilizers has been one of the most successful industries in China in the past two decades. It has not only manifested a remarkable long-term growth rate but also avoided shortterm fluctuations. During the crisis years of the early 1960s when virtually all industries suffered set-backs, the production of fertilizers managed to progress steadily. Its success is attributed to a number of favourable factors. First of all the importance of chemical fertilizers in developing China's agriculture was fully recognized by all leaders in the Party after their early policy of reliance on the mobilization of natural fertilizers had failed. Consequently, in spite of the frequent power struggles, the chemical fertilizer industry has received uninterrupted emphasis and support. Secondly, the technological problems in producing fertilizers are less formidable than in some other industries so that in a relatively short period the Chinese have learned the basic methods of producing fertilizers and of manufacturing new equipment for this industry. Thus, production has been able to expand whether under the foreign embargo or under the self-imposed policy of self-reliance. Finally, there is no serious resource barrier in the provision of key materials for the production of fertilizers.

Natural Photoperiod

The use of different photoperiods (light) were investigated during tambaqui (Colossoma macropomum) juvenile growth under captivity. Light intensity tested was: continuous dark (24hrs without light), natural photoperiod simulation (10hrs of light and 14hrs without light) and continuous light (24 with light). No mortality was recorded among treatments. Significant differences was observed after 50 days of experiment among mean fish weight, fish kept under a continuous darkness showed a better specific growth rate (6.02%) when compared to control fish (natural photo period, 3.67%). Fish exposed to continuous light presented the lowest mean specific growth rate (2.04%). It is possible to improve tambaqui juvenile weight gain performance when kept under continuous darkness.

Tambaqui (Colossoma macropomum) is one of freshwater fish that preferred by the community and also in high demand by fish farmers. It has a high selling value and easy to maintain but the growth is slow. One alternative that can be used to improve the fish growth is making rations with the addition of Moringa oleifera leaves. The aim of this study was to determine the effect of Moringa leaves powder on the growth rate and health of C. macropomum. This study used an experimental method with Completely Randomized Design (CRD) with 6 treatments and 4 replications. The data were analyzed using ANOVA Test in α =95%. The results showed that P3 with the addition of 30% Moringa leaves powder could increase the growth of Colossoma macropomum. An increase in fish body weight, width, and length was 40.1%, 21.6%, and 6.4% respectively.  Results of ocular, reflex, and defensive test showed that the fish were in healthy condition compared to their condition before acclimatization. The conclusions of this study is that the addition of Moringa leaves powder in an influential ration can increase the growth and maintain the health of C. macropomum. M. oleifera daily supplement can be used as a substitute for soy flour to promote growth and health of Colossoma macropomum in the seed phase. The addition of M. oleifera can be used as feed supplements to improve the growth and health of Colossoma macropomum.

Pakan merupakan faktor penting dalam kegiatan budidaya ikan secara intensif. Penggunaan Lemna minor sebagai bahan baku pakan karena mudah didapat dan mengandung nutrisi yang baik. Adanya kandungan serat yang tinggi pada Lemna minor sehingga sulit untuk dicerna dan memerlukan proses fermentasi.  Penelitian ini bertujuan untuk mengetahui pemanfaatan pakan tepung Lemna minor fermentasi terhadap pertumbuhan ikan bawal. Metode  Rancangan Acak Lengkap  (RAL) dengan 4 perlakuan dan 3 ulangan, terdiri dari A tanpa tepung Lemna minor fermentasi, B tepung Lemna minor fermentasi 10%, C tepung Lemna minor fermentasi 20% dan D tepung Lemna minor  fermentasi 30%. Data yang diamati yaitu jumlah konsumsi pakan (JKP), efisiensi pemanfaatan pakan (EPP), Laju pertumbuhan relatif (RGR) dan sintasan. Hasil menunjukkan bahwa perlakuan C (tepung Lemna minor fermentasi 20%) mampu menghasilkan rata-rata JKP sebesar 287,33 g, EPP sebesar 0,052%, RGR sebesar 0,090%/hari dan SR sebesar 100%Feed is an important factor in intensive fish aquaculture activities. Use Lemna minor as a feed raw material because it is easily available and contains good nutrition. The composition of high fiber in Lemna makes it difficult to digest and requires a fermentation process. This study aims to learn how to use Lemna fermentation flour on the growth of pomfret. Method used was completely randomiza design with 4 treatments and 3 replications, consisting of A without Lemna flour fermented, B Lemna flour fermented 10%, C Lemna flour 20% fermentation and D Lemna flour 30% fermentation. Interesting data are the amount of feed consumption, increased feed efficiency (EPP), relative growth rate (RGR) and survival rate. The results showed that the treatment of C (Lemna minor flour fermentation of 20%) was able to produce an average JKP of 287.33 g, EPP of 0.052%, RGR of 0.090%/day and SR of 100%
