Brown tilapia is the descendant of long-finned ornamental tilapia. This is a new kind of tilapia with normal-sized fins. Thus, it is not suitable as an ornamental fish. Despite this, the feasibility of brown tilapia for food fish should be evaluated. The present study aimed to investigate the morphological aspects of brown tilapia in terms of morphometric, meristic, length-weight relationship, condition factor, morphological abnormality, and fluctuating asymmetry compared to those of the NIRWANA Nile tilapia (Oreochromis niloticus) which commonly cultured in Indonesia. The observations were undertaken at the end of the grow-out phase. The grow-out phase was conducted for four months, while the larval rearing and nursery phases were previously conducted for two months. The results showed that, except for the color, the brown tilapia could not be morphologically differentiated from NIRWANA Nile tilapia. The brown tilapia's length-weight relationship and condition factor were similar to those of the NIRWANA Nile tilapia. As such, in NIRWANA Nile tilapia, the brown tilapia exhibited some fluctuating asymmetry with no morphological abnormality. Those overall results suggested that the brown tilapia was considered to have the potential to be developed as a new kind of tilapia food fish.

This research aims to produce seeds from the crossbreeding of nile tilapia (Oreochromis niloticus) of the jabir, nirwana, and sultana strains, as well as Mozambique tilapia (Oreochromis mossambicus). The crosses involved using male jabir nile tilapia with female nirwana nile tilapia and male mozambique tilapia with female sultana nile tilapia. The breeding was conducted in a 1:3 ratio of male to female. The spawning process occurred over a 16-day cycle, followed by a 28-day period of larval rearing. Crossbreeding between jabir and nirwana resulted in a higher spawning rate (17%) compared to the crossbreeding of mozambique and sultana (7%). The specific growth rate of seeds from the jabir and nirwana cross (14%) was not significantly different from the mozambique and sultana cross (13%). The survival rate of seeds from the jabir and nirwana cross (80%) was higher than from the mozambique and sultana cross (70%). Crossbreeding between male jabir nile tilapia and female nirwana nile tilapia exhibited better performance compared to the crossbreeding of male mozambique tilapia and female sultana nile tilapia.

Abstract This study aimed to examine the effect of Gamal leaves flour supplementation in commercial feed on the growth of Nirwana tilapia (Oreochromis niloticus) fingerlings. The experimental design used was a non-factorial completely randomized design consisting of four treatments and four replications. The treatments studied included commercial feed without supplementation of Gamal leaves flour as a control (P0), commercial feed with supplementation of Gamal leaves flour 10% kg−1 feed (P1), commercial feed with supplementation of Gamal leaves flour 15% kg−1 feed (P2), and commercial feed with supplementation of Gamal leaves flour 20% kg−1 feed (P3). Nirwana tilapia fingerlings were stocked at a density of 1 fish L−1. Nirwana tilapia fingerlings size ranges from 2-3 cm. Nirwana tilapia fingerlings maintenance period lasts for 40 days. The Annova test showed that the treatment gave a significant effect on the weight gain, length gain, daily growth rate, and feed conversion ratio (P < 0,05), but did not give a significant effect on the survival rate of Nirwana tilapia fingerlings (P > 0,05). The best dose to increase the growth of Nirwana tilapia fingerlings was commercial feed with supplementation of Gamal leaves flour 10% kg−1 feed.

Abstract High stocking density is an important factor in cultivation to increase the eficency if fish farming for nutrition requirements. High stocking density generally impact on fish physiology and growth performance. However, many studies on individual fish have different growth perfromance from different strain. Some technology had been developed to optimize tilapia production in high stocking density. This study aimed to determine the growth performance of three different strain of tilapia (red tilapia, nirwana tilapia, and jatimbulan tilapia) reared in 20 m3 of round tarpaulin with additional of microbubble generator. This study used an intensive system with 100 fish/m3 of stocking density. The results showed that the microbubble generator was able to increase the carrying capacity of water quality such as increasing dissolved oxygen in the waters, temperature and pH. The high content of dissolved oxygen in the water significantly increasing the growth of tilapia. The highest weight was found in red tilapia with a final weight of 199.56 ± 0.05 gr, followed by Nirwana tilapia with 176.59 ± 0.10 gr, and Jatimbulan tilapia with 153.91 ± 0.06 gr. In addition, the high content of dissolved oxygen in the waters also affect the rearing period of tilapia.

Full textAbstract:
The high cost of commercial feed in Nirwana tilapia aquaculture leads to elevated production costs and reduced profits. As a solution, the provision of natural feed is proposed as an alternative to reduce production expenses. This study aims to compare the growth of Nirwana tilapia fed with three different natural feeds: Tubifex sp., Chironomus sp. larvae, and maggots. The experiment was conducted using a completely randomized design with three replicates for each treatment. The feeding rate was 3% of the fish’s body weight, administered three times a day. The parameters measured included absolute biomass, absolute length gain, daily growth rate (Specific Growth Rate, SGR), survival rate (SR), and water quality during the 30-day rearing period. The results showed that feeding Nirwana tilapia with Tubifex significantly increased growth compared to the control group (commercial pellets), Chironomus larvae, and maggots. The absolute biomass from Tubifex feeding was 5.23 ± 0.89 g, absolute length was 4.2 ± 7.8 cm, SGR was 1.52 ± 0.33%, and SR was 90%. The next highest growth was seen in Chironomus larvae, followed by maggots, with the control yielding the lowest results.

Penampilan fenotipik suatu organisme ditentukan oleh faktor genetik dan dipengaruhi oleh faktor lingkungan tempat organisme tersebut hidup. Dalam beberapa kasus, interaksi antara faktor genetik dengan lingkungan juga berpengaruh terhadap penampilan fenotipik yang dihasilkan. Penelitian ini bertujuan untuk mempelajari interaksi antara faktor genetik dengan lingkungan, daya adaptabilitas dan stabilitas penampilan fenotipik khususnya bobot individu pada empat varietas unggul ikan nila yang dipelihara di tiga lokasi berbeda. Ikan nila varietas GMT, merah NIFI, NIRWANA dan BEST dipelihara di tambak payau di Indramayu, kolam air tenang di Sukamandi dan karamba jaring apung di Waduk Cirata, Kabupaten Cianjur, selama empat bulan pemeliharaan. Benih ikan nila diberi pakan pelet komersial dengan kandungan protein kasar 28%-30%, sebanyak 10%; 7,5%; 5%; dan 2,5% dari biomassa ikan masing-masing pada bulan pertama, kedua, ketiga, dan keempat. Pakan diberikan dengan frekuensi dua kali setiap hari. Hasil penelitian menunjukkan bahwa bobot ikan nila secara nyata dipengaruhi oleh faktor genetik, lingkungan, serta interaksi antara kedua faktor tersebut. Selain ikan nila GMT, tiga varietas ikan nila yang diuji mempunyai adaptabilitas lingkungan relatif sempit, serta stabilitas penampilan fenotipik karakter bobot individu relatif rendah. Hal ini mengindikasikan bahwa pengembangan budidaya ikan nila GMT dapat dilakukan di semua lokasi, sedangkan ikan nila merah NIFI, NIRWANA, dan BEST akan optimal jika dilakukan di lokasi tertentu saja.Phenotypic performance was determined by genetic and environment factors and their interaction. This study was conducted to examinethe present of interaction both of genetic and environment factors, adaptability, and stability of phenotypic performance of four varieties of tilapia which maintained in three different location. GMT, red NIFI, NIRWANA, and BEST tilapia strains were reared for four months in net cages in Cirata reservoir in Cianjur, in earthen ponds in Sukamandi and in brackish water ponds in Indramayu. All fish were fed with commercial pelleted feed contained of crude protein 28%-30%, about 10%, 7.5%, 5%, and 2.5% each day in 1st, 2nd, 3rd, and 4th month, respectively. The results showed that tilapia’s phenotipic performance especially the average body weight was significantly affected by genetic factor, environment factor, and interaction both of them factors. Except the GMT, all tilapia strains used in this study have narrow phenotypic adaptability and stability, especially in average body weight. This results indicated that GMT tilapia strain can be farmed in various areas, but red NIFI, NIRWANA, and BEST tilapia strains are most likely in a specific location.
