Sintasan yang rendah pada pembenihan lobster air tawar tidak terlepas dari karakteristik lobster air tawar yang teritorial pada areal yang terbatas, sering menunjukkan sifat agresif pada umur muda, dan memiliki perilaku kanibalisme. Tujuan dari penelitian ini adalah mengevaluasi pengaruh penggunaan selter yang berbeda terhadap respons stres dan kinerja produksi sehingga dapat menentukan jenis selter yang tepat untuk pendederan lobster air tawar Cherax quadricarinatus. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan dan tiga ulangan. Perlakuan pada penelitian ini adalah penggunaan selter yang berbeda yakni pipa PVC, roster (ventilasi blok), tali rafia, dan tanpa selter (kontrol). Benih lobster air tawar yang digunakan memiliki bobot rata-rata awal berkisar antara 0,60±0,09-0,64±0,02 g dan panjang total rata-rata awal berkisar antara 2,55±0,06-2,61±0,03 cm yang dipelihara dalam sistem resirkulasi selama 60 hari. Perlakuan dengan penggunaan selter ataupun tanpa selter (kontrol) tidak memberikan pengaruh signifikan (P>0,05) terhadap respons stres, namun memberikan pengaruh signifikan (P<0,05) pada kinerja produksi benih lobster air tawar di akhir penelitian. Perlakuan terbaik pada penelitian ini adalah penggunaan selter tali rafia dengan kadar glukosa sebesar 101,00±17,35 mg/dL; protein total sebesar 5,00±0,36 g/dL; sintasan sebesar 86,67± 0,00%; bobot rata-rata akhir sebesar 2,86-3,46 g; panjang total rata-rata akhir sebesar 4,47-5,08 cm; laju pertumbuhan bobot spesifik sebesar 2,92±0,21%/hari; laju pertumbuhan panjang spesifik sebesar 1,15±0,08%/hari; rasio konversi pakan sebesar 2,97±0,05; dan biomassa total sebesar 45,02±1,10 g. Penggunaan tali rafia sebagai selter menjadi perlakuan yang terbaik karena kemampuan tali rafia memisahkan banyak individu sehingga dapat mengurangi kanibalisme dengan cara meminimalkan kontak antarbenih lobster air tawar.The low survival rate in seed production of freshwater crayfish is mainly caused by the territorial behavior of freshwater crayfish which leads to aggressiveness and cannibalism behavior even at a young age. This research aimed to determine the effect of using different nursery shelters on stress responses and production performance of freshwater crayfish Cherax quadricarinatus. This research used a completely randomized design consisted of four treatments, each with triplicate. The treatments used were different shelters made from PVC pipes, ventilation blocks, raffia ropes, and no shelters as controls. The freshwater crayfish seeds had initial weights ranged from 0.60±0.09-0.64±0.02 g, and total length ranged from 2.55±0.06-2.61±0.03 and reared in a recirculation system for 60 days. The results of the research showed that all treatments including controls did not have a significant effect (P>0.05) on stress responses but had a significant effect (P<0.05) on the production performance of freshwater crayfish seed at the end of this research. The seeds reared with raffia ropes shelter had the best production performance indicated by its glucose level of 101.00±17.35 mg dL1, total protein level of 5.00±0.36 g dL1, survival rate of 86.67 ± 0.00%, final average weight of 3.46 ± 0.08 g, final average total length of 5.08 ± 0.12 cm, specific weight growth rate of 2.92±0.21% per day, specific length growth rate of 1.15± 0.08% per day, feed conversion ratio of 2.97±0.05, and total biomass of 45.02±1.10 g. The use of raffia ropes is considered as the best shelter for freshwater crayfish seed as it provides more space to separate individual seeds which can reduce cannibalism behaviour due to minimum contact between individual seeds.

This study was conducted to investigate and compare the growth performance of four Tilapia strains in hapa nursing with the aim to find out the best strain of tilapia. The research was conducted by four treatments with five replicates each. The tilapia fry were collected from, BFRI source from BFRI HQ, Mymensingh stocked in Treatment-1; unknown source from Hi-Tech Tilapia Hatchery Dagoanbhuiya, Feni in Treatment-2, Philipine strain from Green Field Tilapia Hatchery, Laxmipur in Treatment-3 and fry from Breeding Cohort, Sonar Bangla Hatchery, Bamna, Barguna in Treatment-4. The Individual stocking weight (g) of fry was average 0.01g. The fries were stocked in 12 hapa at same stocking density of 1200 fish/m2. Each of the hapa was 2m × 1m × 1m size and fixed in an earthen ponds. Supplementary feed with 31.29% of protein level consisting of rice bran (25%), mustard oil cake (15%), wheat flour (30%) and fish meal (30%) was given at the rate of 40% of their body weight per day manually, four times a day at the beginning of the experimental period and reduced to 25% of their body weight and continued up to harvesting period. The results showed that fry of Treatment-4 strain was the best strain and had significantly (p < 0.05) higher final mean body weight (FMBW), mean body weight gain (MBWG), specific growth rate (SGR) (9.75%), gross yield (GY) (2.13) and Net yield (NY) (2.12) than the Treatment-1 , Treatment-2 strains and Treatemnt-3 strain. Treatment-4 strain had the fastest growth rate, whereas the lowest performing strain was that from Treatment-2. We also analyzed survival rate of the fish from stocking to harvest, survival rate was highest in Treatment-4 strain (80%) where lowest is Treatment-3. Treatment-4 stain also showed the best feed conversion ratio (FCR) 1.62 than others. Considering the overall performance it can be concluded that tilapia strain collected from Breeding Cohort source is best among the four strains. However, further research may still be needed to compare more strains from different water body to evaluate the genetic potential for Tilapia.International Journal of Natural Sciences (2015), 5(2) 98-106

This study aimed to evaluate the impact of plant-based food additives on growth performance, body composition and survival of Nile tilapia. Four isonitrogenous (25% CP) and isolipidic (13% CL) experimental diets were prepared and designated as R1, R2, R3, and R4. R1 contains (3% Cymbopogon citratus), R2 contains (3% Ocimum basilicum), R3 contains (3% Mentha spicata) and R4 (control or 0% additive). 180 Nile tilapia fry with an initial average weight of 0.2g were distributed in 12 plastic tanks (50 L/tank) at the stocking density of 15 fish per tank in an isolated system. Fish were fed with experimental diets 3 times per day (8:00 am, 1:00 pm and 5 :00 pm) for 3 months. After 90 days of experiment, the results revealed that the final average weight ranged from 2.62g to 8.00g, the absolute average weight gain (AAWG) from 2.42 to 7.8g, the feed conversion ratio (FCR) from 1.31 to 2.67 and specific growth rate (SGR) from 3.06 to 4.36%/d. The survival rate (SR) varied between 64 and 100%. Of the parameters studied such as the absolute average weight gain (AAWG), the specific growth rate (SGR), the feed conversion ratio (FCR), and the survival rate, the best were obtained by the group of fish fed with the R2 diet containing 3% Ocimum basilicum. The results of the analysis of the flesh showed that the addition of 3% O. basilicum does not modify the contents of dry matter, crude protein, and ash but slightly increased the fat content. Based on the results, the inclusion of natural plant-based food additive (3% Ocimum basilicum) in the diet of Nile tilapia improved the parameters of growth, feed efficiency, and survival.
