Triploid striped catfish Pangasianodon hypophthalmus: growth performance and gonadal development

ABSTRACT This study was aimed to evaluate the growth performance and gonadal development of diploid and triploid striped catfish Pangasianodon hypophthalmus. Triploids were produced through a heat shock method at 42 °C for two minutes, at two minutes after fertilization. Before treatment performed, group of triploid and diploid were separated through nucleolus counting confirmed cromoseme counting. Five individual of each group at the age of nine months were tagged and reared for two months. Parameter of growth performance, feed conversion ratio, and survival rate were analysed using independent-samples t-test at confidence interval 95%, while gonadosomatic index (GSI) and gonad histology were analysed descriptively. No significant differences were observed between diploid and triploid fish in terms of growth performance, feed conversion ratio, and survival rate (P>0.05) during the two months rearing period, while GSI was higher in diploid (P<0.05) compared to triploid females. Histological observations of triploid female gonads showed early development stage, indicating sterility through symptoms such as oocytes degradation and abnormal development. Meanwhile, male gonad developed faster compared to female as spermatids were found in several lobules. As conclusion, diploid and triploid striped catfish P. hypophthalmus growth performance did not differ up to the age of 11 months, although some sterility symptoms were observed in both male and female. Keywords: diploid, triploid, growth, gonad, Pangasianodon hypophthalmus ABSTRAK Penelitian ini bertujuan untuk mengevaluasi performa pertumbuhan dan perkembangan gonad ikan patin siam Pangasianodon hypophthalmus diploid dan triploid. Triploid diproduksi dengan kejut suhu panas pada suhu 42 °C selama dua menit, pada dua menit setelah fertilisasi. Sebelum pengujian, kelompok diploid dan triploid dipisahkan dengan menganalisis jumlah nukleolus yang dikonfirmasi dengan penghitungan jumlah kromosom. Masing-masing lima ekor ikan diploid dan triploid pada umur sembilan bulan ditandai dan dipelihara selama dua bulan. Parameter pertumbuhan, rasio konversi pakan, dan kelangsungan hidup dianalisis menggunakan independent-samples t-test pada selang kepercayaan 95% sedangkan gonadosomatik indeks (GSI) dan histologi gonad dianalisis secara deskriptif. Pertumbuhan, rasio konversi pakan, dan kelangsungan hidup antara diploid dan triploid selama dua bulan pemeliharaan tidak menunjukkan perbedaan yang nyata (P>0,05). Nilai GSI diploid lebih tinggi (P<0,05) dibandingkan triploid, baik pada jantan maupun betina. Hasil histologi menunjukkan bahwa gonad ikan patin betina masih pada tahap perkembangan awal. Namun, indikasi steril terlihat dengan adanya degradasi oosit dan perkembangannya yang terganggu. Gonad jantan berkembang lebih cepat dibandingkan betina, dengan ditemukannya spermatid pada beberapa lobule. Gonad jantan triploid menunjukkan adanya gejala sterilitas tetapi tidak permanen, sebagian masih mampu berkembang hingga fase spermatid, namun jumlahnya lebih sedikit dibandingkan diploid. Berdasarkan penelitian, disimpulkan bahwa pertumbuhan antara ikan patin siam diploid dan triploid hingga umur 11 bulan tidak menunjukkan perbedaan, akan tetapi gejala sterilitas ditemukan baik pada jantan maupun betina triploid.

Abstract. Nugroho RA, Hardi EH, Sari YP, Aryani R, Rudianto. 2019. Growth performance and blood profiles of striped catfish (Pangasianodon hypophthalmus) fed leaves extract of Myrmecodia tuberosa. Nusantara Bioscience 11: 89-96. The application of plant extract in the aquaculture field is gaining momentum. This study aimed to determine the effects of M. tuberosa Jack leaves extract on the growth performance and blood profiles of striped catfish (Pangasianodon hypophthalmus). 400 fish with an initial average weight of 1.54 ± 0.02g were randomly divided into five groups and fed with different concentration of M. tuberosa Jack leaves extract (0.25, 0.5, 1, 2%) and control diet for 80 days. Growth performance, feed conversion rate, feed efficiency, survival rate, morphometric, and hematological profile of the fish were evaluated at the end of the trial. The results found that fish fed 0.5-1% concentration had significantly higher (P<0.05) growth, feed conversion rate, feed efficiency, morphometric value, survival, white blood cell, hemoglobin, neutrophil, lymphocyte, and monocyte than control. Meanwhile, supplementation of 2% MTE in the diet of fish reduced growth, feed utilization, viscerosomatic index, and morphometric values but increased red blood cell. All the supplemented diets decreased platelet of fish. The findings indicated that supplementation 0.5-1% of MTE is beneficial to the growth and blood profile of fish through the increment of growth indices, feed utilization, white blood cell, hemoglobin, neutrophil, lymphocyte, and survival rate of fish.

Hibridisasi merupakan salah satu teknik pemuliaan ikan dalam rangka mendapatkan varietas unggul sehingga mampu meningkatkan nilai produksi suatu komoditas ikan yang dibudidayakan. Tujuan penelitian ini adalah untuk mengevaluasi performa pertumbuhan, koefisien variasi, dan nilai heterosis dari hasil persilangan tiga spesies ikan patin sebagai tetua, yaitu patin siam (Pangasianodon hypophthalmus), patin jambal (Pangasius djambal), dan patin nasutus (Pangasius nasutus) pada tahap pendederan II. Induk ikan patin siam dan patin jambal yang digunakan merupakan ikan yang sudah dirilis sebagai ikan budidaya, sedangkan induk ikan patin nasutus berasal dari perairan umum dan sedang dalam proses domestikasi sebagai ikan budidaya. Persilangan yang dibuat adalah: A) f patin jambal >< m patin jambal (JJ); B) f patin siam >< m patin jambal (SJ); C) f patin siam >< m patin siam (SS); D) f patin siam >< m patin nasutus (SN); dan E) f patin nasutus >< m patin nasutus (NN). Penelitian dilakukan secara indoor hatchery selama 30 hari pemeliharaan. Nilai heterosis dihitung berdasarkan laju pertumbuhan spesifik (LPS) bobot, LPS panjang total, dan sintasan. Hasil penelitian menunjukkan bahwa performa pertumbuhan, sintasan, dan konversi pakan ikan hasil persilangan tidak berbeda nyata (P>0,05). Ikan patin SN memiliki performa yang lebih baik dari tetuanya dengan nilai heterosis bobot akhir, LPS bobot, panjang total, LPS panjang total, dan sintasan berturut-turut sebesar 110,87%; 19,78%; 36,14%, 36,09%; dan 15,04%; serta nilai koefisien variasi berkisar antara 0,00-11,08. Bobot akhir, panjang total dan sintasan ikan patin SJ juga lebih baik dari tetuanya dengan nilai heterosis berturut-turut sebesar 46,00%; 11,27%; dan 2,27%; namun untuk heterosis LPS bobot dan LPS panjang total bernilai negatif (-6,65% dan -1,01%), serta nilai koefisien variasi berkisar antara 0,00-12,75. Berdasarkan hasil penelitian tersebut menunjukkan bahwa ikan patin hibrida SN berpotensi sebagai ikan budidaya dalam rangka peningkatan produksi ikan patin daging putih selain dari ikan patin hibrida SJ (pasupati) yang telah dirilis ke masyarakat.Hybridization is a fish breeding technique in order to obtain high yielding varieties as to increase the production value of a farmed fish. The purpose of this study was to evaluate the growth performance, the coefficient of variation and heterosis value of the result of crossing three species of catfish as a parent, which was striped catfish (Pangasianodon hypophthalmus), jambal catfish (Pangasius djambal) and nasutus catfish (Pangasius nasutus). Crosses made were A) f jambal catfish >< m jambal catfish (JJ); B) f striped catfish >< m jambal catfish (SJ); C) f striped catfish >< m striped catfish (SS); D) f striped catfish >< m nasutus catfish (SN); and E) f nasutus catfish >< m nasutus catfish (NN). The study was performed at the indoor hatchery for 30 days. Heterosis values were calculated based on the specific growth rate (SGR) final weight, SGR total length, and survival rate. The results showed that growth performance, survival rate, and feed conversion were not significantly different (P>0.05). Catfish SN has a better performance than the parent with the value of heterosis at final weight, SGR weight, total length, SGR total length, and survival rate of 110.87%, 19.78%, 36.14%, 36.09%, and 15.04%, respectively. The coefficient of variation ranged from 0.00 to 11.08. Final weight, total length, and survival of catfish SJ were also better than the parent with the heterosis value of 46.00%, 11.27%, and 2.27% respectively, but for heterosis SGR of the weight and the total length were negative (-6.65% and -1.01%) and the coefficient of variation ranged from 0.00 to 12.75. These results indicated that the hybrid catfish SN has a great potential as fish farming in the hope of increasing the production of white meat catfish hybrid apart from SJ (Pasupati) that have been released to the public.

Foot Disease

Footpad dermatitis (FPD) is a major foot disease in modern poultry production, and it affects both poultry health and animal welfare. It refers to inflammation and necrotizing lesions on the plantar surface of the footpads and toes. We investigated the effects of providing a swimming pool and different floor types on growth performance and FPD score in indoor-reared White Roman geese. Forty-eight male and 48 female White Roman geese were randomly allocated to pens with or without a swimming pool and with either mud or perforated plastic floor and reared from 15 to 84 days of age. Growth performance measurements included feed intake (FI), weight gain (WG), and feed conversion ratio (FCR). FI, WG, and FCR were significantly decreased at various growth periods in geese provided with a pool. Lower WG and bodyweight for the perforated plastic floor group were found at 15–28 and 28 days of age, respectively. The geese reared on the perforated plastic floors without a pool had higher FPD scores at 70 and 84 days of age than those with other rearing conditions. A higher incidence of FPD score 1 was observed in geese raised without a pool. In conclusion, providing a pool can improve footpad health in indoor-reared White Roman geese but may not benefit growth performance.

Abstract(An experiment with two groups of East Balkan pigs – castrated males (n=10) and females (n=10), was carried out to study the growth performance and fattening abilities of the animals from the weaning until slaughter. The pigs were included in the trial at 60 day age. The average live weight of the castrated males was 8. 65±1.08 kg and for the females, 8.5±0.62 kg.The pigs were reared using traditional technology, grazing on natural pastures in the Strandzha mountain, Bulgaria. In autumn, acorns were naturally present in their diet. According to the category, the animals additionally received ground organic feed (50% barley and 50% wheat). The trial lasted 304 days (from February to November, 2019). During this period the final live weight of the male castrated pigs reached 88.00 kg while that of the females was 84.4 kg. The difference, however, was not significant. Furthermore, no significant differences in the growth performance characteristics that could be attributed to the sex of the animals were observed. The average daily gain of both sexes tended to be lower in summer and higher in autumn. The feed conversion ratio was higher in summer. The animals showed high average daily weight gain at pasture when their live weight was over 50 kg.
