Abstract

German cockroach (Blattella germanica L.), is a residential insect pest and vector of various diseases. To control its population, alternative chemical control models with Fipronil 0.03% are now being developed. Fipronil has been proven to be effective and has no resistance. To increase the effectiveness of the bait in controlling German cockroaches, a fipronil 0.03% combination needs to be developed with a phagostimulant bait of bananas, durian, erythisol sugar, and sugar formulation, so this study needs to be done. This study used an experimental method with a randomized block design (RBD), five treatments such as A: bait with a combination of banana phagostimulant and 0.03% fipronil, B: bait with a combination of durian phagostimulant and 0.03% fipronil, C: bait with a combination erythisol phagostimulant and 0.03% fipronil, D: bait with a combination of sugar phagostimulant and 0.03% fipronil, K: bait with a combination of matrix and fipronil 0.03% (control positive) was used for the interest test, and bait with a matrix without fipronil 0.03% (control negative) was used for mortality testing. The observations the average results for durian, banana, sugar formulated, erytrisol sugar and controls, respectively 20%, 20%, 21.6%, 12.4%, and 22.8%, while the results bait consumed with durian stimulation are 0.29g, banana 0.31g, sugar formulation 0.28g, erytrisol sugar 0.26g and control 0.24g. However, based on statistical tests, the results of the interest test with the feed consumption test between treatments showed no significant difference (p>0.05). The test results in mortality of cockroaches Germany's feed with phagostimulan durian, banana, formulations sugar, sugar erytrisol and control consecutively 98% 100 %, 98%, 98%, and 20%, based on the statistical test there is a significant difference (p<0.05), where the difference based on the Duncan test is their treatment compared to control.

Abstract

Ikan sidat (Anguilla bicolor McClelland) merupakan ikan katadromous yang sulit matang gonad dalam kondisi budidaya, sehingga perlu dilakukan penelitian untuk mengkaji nilai IKG, IHS, hubungan antara IKG dan panjang gonad relatif ikan sidat hasil budidaya. Tujuan dari penelitian ini untuk mengetahui nilai IKG, IHS, hubungan antara IKG dan panjang gonad relatif ikan sidat hasil budidaya pada ukuran berbeda dan mengetahui korelasi antara IKG dengan Panjang Gonad Relatif ikan sidat hasil budidaya. Penelitian dilakukan dengan metode survei secara purposive random sampling. Sampel ikan sidat sebanyak 29 ekor diperoleh dari pembudidaya ikan sidat di wilayah Cilacap dikelompokkan berdasarkan fase reproduksinya yaitu yellow eel dan silver eel. Variabel yang diamati ialah panjang gonad relatif sebagai variabel bebas dan IKG sebagai variabel terikat. Parameter yang diukur, yaitu panjang tubuh ikan, bobot tubuh ikan, bobot gonad, panjang gonad, dan bobot hati. Hasil yang didapat pada penelitian ini, rata-rata panjang gonad fase yellow eel 16,93 ± 2,09 cm, sementara fase silver eel 19,93 ± 3,46 cm. Rata-rata IKG yellow eel 1,356±0,992 %, sementara silver eel 2,408±1,053 %. Hasil rata-rata IHS fase yellow eel 1,163±0,201 % dan silver eel sebesar 1,339±0,264 %. Analisis korelasi Spearman’s Rank antara panjang gonad relatif dengan IKG didapatkan nilai signifikansi sebesar 0,167 (P > 0,05). Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa Nilai IKG dan IHS Anguilla bicolor McClelland hasil budidaya pada ukuran berbeda memiliki nilai yang berbeda. Tidak terdapat hubungan yang signifikan antara panjang gonad relatif dengan IKG.

Abstract

Diopatra claparedii Grube, 1878, is a tubicolous polychaete species widely used as fishing bait by local anglers in Cilacap, Central Java, Indonesia. Little is known about its biological characteristics despite its ecological and economic importance. This study aimed to examine the survival rate, growth, metabolic rate, and osmoregulatory capacity of D. claparedii under different salinity conditions. The experiment was conducted using plastic containers (20 × 30 × 25 cm) filled with a muddy substrate and water at four salinity levels: 10, 15, 20, and 25 ppt, with each treatment replicated five times. The results showed that the survival rate of D. claparedii ranged from 87% to 93%, while its growth varied between 0.17 and 0.58 g. The metabolic rate, measured in terms of oxygen consumption, ranged from 0.201 to 0.467 mg·g-¹·h-¹. The  osmoregulatory capacity of the worms varied between 1.26 and 1.54 mOsm·kg-¹ solvent. Statistical analysis indicated that salinity did not significantly affect survival (p> 0.05). However, it significantly influenced growth, metabolic rate, and osmoregulatory capacity (p< 0.05). The results suggested that a 15–25 ppt salinity range was more favorable for the species, with 20 ppt being the most optimal level for its maintenance and growth. This study highlights the potential for cultivating D. claparedii under controlled conditions, providing a sustainable alternative to wild harvesting. As polychaete farming has been successfully implemented in several countries, similar efforts could be applied in Indonesia to support local fisheries while conserving natural populations.

Abstract

ABSTRACT. Cultivation of hard-lipped barb (Osteochilus vittatus) increased in the district of Banyumas, Indonesia. Supplementation Spirulina platensis and Chlorella vulgaris has lots utilized in field aquaculture as high nutritious food to increase fish production. Evaluation digestibility to S. platensis and C. vulgaris in hard-lipped barb fish can done with measurement composition body and activity enzyme digestion. The purpose of this study was to know the influence of supplementation of S. platensis and C. vulgaris and to find the most appropriate composition of supplementation to enhance body composition and digestive enzyme activity of hard-lipped barb. The study was conducted experimentally with completely randomized design (CRD) and consisting of five Treatments: P0 = without supplementation as control; P1 = S. platensis 6 g.kg-1; P2 = C. vulgaris 4 g.kg-1; P3 = ( S. platensis 3 g + C. vulgaris 2 g).kg-1; and P4 = ( S. platensis 2 g + C. vulgaris 3 g).kg-1, in four replicates. The results showed S. platensis and C. vulgaris increase hard-lipped barb protein, fat and fiber levels. C. vulgaris and combinations of S. platensis + C. vulgaris enhance activity trypsin-like, lipase, amylase, and alkaline phosphatase in foregut, hindgut, and hepatopancreas. C. vulgaris and S. platensis can be given as supplement of hard-lipped barb feed to enhance enzyme activity that contributing digestion​ to enhance body composition.

Abstract

ABSTRACT. The critical problems in eel cultivation are slow growth due to low digestibility and high feed conversion. This shows the need to understand the biochemical composition of eel to obtain information about the physiological condition, energetic adaptation, habits, nutritional value, and industrial uses. Nutritional data are also essential to develop a suitable processing method that enables eel to be consumed throughout the year while respecting state-imposed limitations to protect the species. Despite the significant contribution, there has been no data about the biochemical composition and the digestive enzyme activity of eel species such as Anguilla bicolor McClelland 1844, during the reproductive phase. Therefore, this study aimed to evaluate the biochemical composition of A. bicolor McClelland and the digestive enzyme activity during the reproductive phase. The experiment was conducted through a survey on eels in the reproductive phase with an average weight and length of yellow (106.00 ± 38.1 g and 42.00± 5.78 cm) and silver eel (362.89 ± 88.93 g and 59.86 ± 7.39 cm) respectively. The results showed that Nitrogen Free Extract (NFE) did not substantially alter between different phases, while the percent protein, lipid, ash, and fiber had significant variation (p<0.05). The activity of pepsin differed in various phases (p<0.05), while the activity of trypsin, amylase, and lipase of A. bicolor did not vary (p>0.05). The yellow eel had a higher body protein composition and pepsin activity than the silver eel, although the biochemical composition and other enzyme activities were similar. In summary, the biochemical compositions, and digestive enzymes of A. bicolor varied depending on their phases. Moreover, further studies were recommended to understand the biochemical composition of A. bicolor and digestive enzyme activity during the reproductive phase.
