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.

Marker-assisted selection in genetic improvement of striped catfish is useful in the breeding program of the fish. Five microsatellite markers were characterized in the largest (4.03 kg ± 1.67 kg) and smallest (1.41 kg ± 0.22 kg) individuals. Five polymorphic loci were then used to genotype 160 individuals and the associations between their genotypes and growth traits were examined. The result showed that twenty-seven alleles were detected in striped catfish. The number of alleles per locus (NA) ranged from 4 to 7, with an average of 5.4 alleles per locus. The effective number of alleles per locus (NE) ranged from 3.940 to 6.939, with an average of 5.32 alleles per locus. HO and HE ranged from 0.125 to 0.944 (mean value of 0.472) and from 0.564 to 0.775 (mean value of 0.697), respectively. PIC ranged from 0.573 to 0.799 (mean value of 0.706), showing that they were highly polymorphic loci. Only one microsatellites loci (Pg13) that showed significant differences (P<0.01) in the associations between their genotypes and growth traits, while Pg3 and Pg14 were significantly associated with the standard length (P<0.01) and body weight (P<0.05). However, the Pg1 and Pg2 were not significantly associated with the body weight and standard length. Four genotypes of three loci were positively correlated with the growth traits (body weight and standard length) i.e. genotypes 194/194 for Pg3, 227/227 and 229/229 for Pg13, 279/279 for Pg14. These four genotypes can be used to identify growth traits in the molecular marker-based selection of a breeding program.

Indigenous Goat

In 2008, a breeding programme was designed to develop hybrid goat suitable for the rainforest agro-ecological zone of South-Eastern, Nigeria. Two indigenous goat breeds namely, Red Sokoto (RS) and West African Dwarf (WAD) goats were utilized and mated in a main (RS x WAD), reciprocal (WAD x RS) and pure line (RS x RS and WAD x WAD) fashion. A total of 74 progenies were generated from the matings and were evaluated for 12week growth performance. As part of the ranking procedure, a selection index was constructed based on two major body components namely body weight (BWT) and heart girth (HGT) to objectively determine the genetic worth of the growing pure and crossbred progenies of Red Sokoto and West African Dwarf kids. The results showed that average body weight (BWT) of RS x RS (5.29±0.13kg) and RS x WAD (5.14±0.21kg) buck kids were similar but significantly (P< 0.05) heavier than that of their WAD x RS (4.84 + 0.17kg) and WAD x WAD (4.79 + 0.17kg) counterparts. The performance of crossbred RS x WAD compared to WAD x RS and WAD x WAD buck kids indicate that the main crossbred kids sired by Red Sokoto bucks but nursed by WAD dams received superior sets of genes from their large-sized sire. The RS x WAD buck kids in particular, had significantly longer body length (BLT), height-at-withers (HWT) and HGT than WAD x RS and WAD x WAD kids. The phenotypic and genetic correlations of BWT and HGT in both sexes for the different genotypes were high and positive which were indicative of the nature of association between these conformation traits in goats. Heritability estimates (h2) for BWT and HGT in males and females kids ranged from 0.31 – 0.36 versus 0.28 – 0.30, respectively in most of the growing kids. The relative economic values (REV) of chosen traits were generally higher for male kids compared to their female counterparts. Phenotypic variances for BWT and HGT in male and female kids ranged from 0.65 – 0.80. The selection index values were highest in male and female kids of RS x RS, followed by RS x WAD, while WAD x RS kids ranked low and WAD x WAD kids ranked the least. Thus, indicating that selection and improvement of growth traits in these pure and crossbred kids would be in favour of the RS x RS and RS x WAD individuals.

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.
