Growth And Survival

The domestication and culture of freshwater shrimp native of tropical and subtropical American Pacific zone requires the study and development of technologies in open systems where their response to types of farming, feeding and management strategies generate practical information for the production of this species. The aim of this study was to evaluate the effect of stocking density on growth and survival in M. americanum juvenile-adult, cage-cultured and to determine the optimal density for grow-out production. The caridean shrimp Macrobrachium americanum was cultured for 152 days in a 16 cage-culture (3 m3 each) at densities of 1, 3, 6 and 9 org / m3, respectively, with stocking sizes from 12.1 ± 1.7 to 13.5 ± 2.3 g. The prawns were fed twice daily with Camaronina 35%. Water quality parameters were within standard range for caridean shrimp culture. There was a significant effect of density on final weight, growth rate, specific growth rate, K condition and survival, and an inversely proportional relationship with the feed conversion ratio. The growth was affected by density, resulting to a maximum increase of 6 org / m3 in the asymmetry of the prawn and also increasing the number of small organisms by 9 org / m3. However, it is necessary to study such aspects as the rate and frequency of feeding, the initial size-grade and the implementation of shelter, among others.

One of the freshwater fishes thatbegan to bedeveloped is Wader fish, but there is still a lot of information that has notbeen supportedon fish farming techniques. One of them is the optimal stocking density for cultivation. The purpose of this study was to study the effects of different stocking densities on the growth and survival rates of the WaderCakulfish (Puntiusbinotatus).This research was conductedin May - July 2018. The method used in this study was to use aCompletely Randomized Design with 4 training, namely P1 (2 fish/liter), P2 (3 fish/liter), P3 (4 fish/liter) and P4 (5 fish/liter).Each treatment was repeated3 times. The main parameters were absolute growth rate (length and weight gain)(GR), specific growth rate (SGR), survival rate (SR), and feed conversion ratio (FCR).Data were analyzedusing ANOVA (analysis of variance) and continued with the Least Significant Difference Test. The results showed that different stocking densities gave significant values (P <0.05) for GR, SGR, SR and FCR comparisons. The best treatment in this study was P1 with a growth value of 0.31 ± 0.01 gram, SGR 3.50 ± 0.03%, Long Growth 1.97 ± 0.05 cm, SR 85.07 ± 2.17% and FCR 1.47 ± 0.02. P1 (2 fish/liter) is the best maintenance to increase the growth, survival rate, and feed efficiency of thecakulwader fish.

One way to increase cultivation productivity is by increasing stocking. Gouramy is a freshwater commodity that has a fairly slow growth performance. This study aims to determine the growth performance of gouramy reared at different stocking densities. The 3 cm gourami are reared in a pond containing 35 liters of water. ponds P1 (30 heads), P2 (50 heads), P3 (100 heads), P4 (150 heads), P5 (200 heads) each was repeated 3 times. Growth rate (GR), specific growth rate (SGR), survival rate (SR), and feed conversion ratio (FCR) were measured and analyzed for variance (ANOVA) followed by LSD. The results showed that the fish reared in pond P1 showed the best GR, SGR, FCR, and SR (3.8 g, 3.99 %, 96 %, and 1.11 respectively). The lower the density, the better the growth performance but based on efficiency and productivity the best is at P2.

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

<p>This experiment was conducted to study the stocking density effect on growth and survival rate of giant gouramy seed in the aquarium. Fish were stocked at the density of 2.5; 5.0; 7.5 and 10 individual/l with average initial weight and length were 0.013 g and 5.56 mm, respectively. Fish were fed with silkworm (<em>Tubifex</em> sp.) <em>ad libitum</em> in the morning and evening for 22 days of experiment. Aquarium was siphoned and water was changed everyday for maintaining good water quality. Result showed that survival rate remain high in all treatment (93.5 - 95.5%). Increasing stocking density from 2.5 to 10 individual/I did not affect survival rate. On the other hand growth rate and feed efficiency decreased, while fish yield increased. Stocking density of 2,5 individual/l gave  the highest daily growth rate, individual growth rate, growth in length and feed efficiency of 12.94%, 0.0081 g/day, 16.84 mm and 12.51%; respectively. The highest value for fish yield (0,0360 g/l/day) was obtained from stocking density of 10 individual/l</p> <p>Key words: stocking density, seed, survival rate, growth rate, giant gouramy <em>Osphrenemus goramy</em></p> <p> </p> <p>ABSTRAK</p> <p>Keterbatasan pengadaan benih ikan gurame (<em>Osphronemus gourame </em>Lac.) disebabkan oleh tidak seimbangnya jumlah benih yang tersedia dengan kebutuhan usaha pembesaran. Teknik pembenihan yang digunakan sampai saat ini relatif sederhana dengan cara tradisional. Pemeliharaan gurame secara terkontrol di akuarium dapat menjawab tantangan dalam teknologi pembenihan gurame sekaligus sebagai sarana pola budidaya secara bertahap yang sedang berkembang saat ini. Produksi yang tinggi akan dicapai dengan pemeliharaan pada kepadatan yang tinggi. Pada keadaan lingkungan yang baik dan pakan yang mencukupi, peningkatan kepadatan akan disertai dengan peningkatan hasil. Jumlah ikan yang ditebar pada penelitian ini disesuaikan berdasarkan perlakuan yaitu 2,5; 5,0; 7,5 dan 10 ekor/l. Pengamatan terhadap ikan dilakukan sampai hari ke-22. Hasil pengamatan menunjukkan bahwa peningkatan kepadatan 2,5 - 10 ekor/l pada pemeliharaan benih gurame di akuarium mempengaruhi pertumbuhan, hasil dan efisiensi pakan, namun tidak berpengaruh terhadap kelangsungan hidup. Dengan meningkatnya padat penebaran, laju pertumbuhan dan efisiensi pakan semakin menurun, sedangkan hasil (<em>yield</em>) semakin meningkat.

This study aims to determine the effect of different doses of booster grotop in feed on the growth and survival of Asian Redtail (Hemibagrus nemurus) maintained in peat swamp media. This research was conducted from 27 March - 05 May 2020 at the Laboratory of Aquaculture Technology, Faculty of Fisheries and Marine, University of Riau. The container used was an aquarium measuring 60 cm x 40 cm x 40 cm as many as 15 units with a stocking density of 12 fish/60 L. This study used a completely randomized design method (CRD) one factor with five levels of treatment and three repetitions. The level of treatment applied in the study was P0 = without giving Boster Grotop (Control), P1 = dose of Boster Grotop 25 g/kg of feed, P2 = dose of Boster Grotop 30 g/kg of feed. P3 = dose of Boster Grotop 35 g/kg of feed and P4 = dose of Boster Grotop 40 g/kg of feed. The results showed that giving boster grotop with different doses in the feed had a significant effect (P<0.05) on growth but had no significant effect (P>0.05) on the survival rate of the Asian Redtail seeds. The best treatment was found at a boster grotop dose of 40 g/kg of feed, which produced protease enzyme activity (0.1731 IU/mL), total weight growth (5.11 g), total length growth (3.73 cm), specific growth rate (3.67%), feed efficiency (72.30%), feed conversion (1.38), survival rate (86.11%).
