Organic acids, worms, and other high protein substances, containing most of the essential amino acids, have been proven to bean excellent food additive for fish and in aquaculture, especially for shrimp culture. The worm Eisenia foetida and vermicompost sub products have been used as a protein source because of their high protein content, between 50 and 67%; they have been included in experimental aquatic feeds, but their use is less known in shrimp culture and has not been tested as a food complement for shrimps. In this study, we added microcapsules with liquid vermicompost as a natural immune enhancer to stimulate disease resistance in shrimp, but they were used also as a complement in shrimp food to observe their survival and growth. Ground commercial shrimp food (CSF) with 40% protein was added to each of eight treatments as follows: A2:CSF+2% of cow manure microencapsulated liquid vermicompost (CMMLV); A3:CSF+3% of CMMLV; A5:CSF+5% of CMMLV; V2:CSF+2% cafeteria wastes microencapsulated liquid vermicompost (CWMLV); V3: CSF+3% CWMLV; V5: CSF+5% CWMLV; CNE:CSF + microencapsulated distilled water, and CN: CSF alone. Initial and average weight gain did not depict statistically significant differences among treatments, but there were significant differences in the specific growth rate and survival. The use of liquid vermicompost resulted in a plausible option to enhance shrimp nutrition. Further studies must be done to test how much shrimps can grow in a longer period and whether this additive can be an option to prevent shrimp diseases.

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.

Limbah cair tambak udang vaname (L. vannamei) merupakan hasil buangan dari proses budidaya yang umumnya langsung dibuang ke perairan umum. Limbah tersebut masih mengandung sejumlah unsur hara yang diperlukan untuk pertumbuhan organisme pada tingkatan trofik dibawahnya, salah satunya adalah mikroalga Chlorella sp. Namun, pada limbah tersebut masih ditemukan sejumlah organisme yang mengganggu pertumbuhan Chlorella sp. sehingga limbah harus disterilkan terlebih dahulu sebelum digunakan untuk menumbuhkan mikroalga tersebut. Tujuan dari penelitian ini adalah untuk mengetahui dosis limbah cair tambak udang vaname steril dalam produksi Chlorella sp. Penelitian ini menggunakan metode eksperimental dengan 4 perlakuan, yaitu A (dosis limbah 25%), B (dosis limbah 50%), C (dosis limbah 75%), dan D (dosis limbah 100%); masing-masing perlakuan diulang sebanyak 3 kali. Hasil penelitian menyatakan bahwa perlakuan D memberikan produksi Chlorella sp. tertinggi yang dapat dilihat dari kepadatan sel dan laju pertumbuhan spesifik pada saat puncak pertumbuhan, yaitu 2.833.333 sel/mL dan 0,472. Dari hasil penelitian ini dapat disimpulkan bahwa limbah cair tambak udang vaname steril dengan dosis 100% dapat digunakan untuk mengkultur Chlorella sp. skala laboratorium dengan menghasilkan produksi mikroalga tertinggi. Diharapkan limbah yang berasal dari hasil budidaya udang vaname dapat dimanfaatkan untuk mengkultur mikroalga sehingga mengurangi pencemaran yang terjadi di perairan umum sekitarnya. Liquid waste of vaname shrimp ponds (L. vannamei) is the result of waste from the cultivation process which is generally discharged directly into public waters. The waste still contains a number of nutrients needed for the growth of organisms at the lower trophic level, one of which is Chlorella sp. However, in these wastes there are still organisms that interfere with the growth of Chlorella sp. therefore the waste must be sterilized before using it to grow the microalgae. The purpose of this study was to determine the dose of liquid waste of sterile vaname shrimp ponds in the production of Chlorella sp. This study used an experimental method with 4 treatments, namely A (25% waste dose), B (50% waste dose), C (75% waste dose), and D (100% waste dose); each treatment was repeated 3 times. The results of the study stated that treatment D gave the production of Chlorella sp. the highest can be seen from cell density and specific growth rate at the peak of growth, which is 2,833,333 cells / mL and 0.472. The results of this study can be concluded that sterile liquid waste of vaname shrimp ponds with a dose of 100% can be used to culture Chlorella sp. laboratory scale by producing the highest microalgae production. It is expected that waste derived from vaname shrimp culture can be used to cultivate microalgae so as to reduce pollution in the surrounding public waters

Background: The study of the zootechnical performance of Tilapia cabrae and Oreochromis schwebischi was carried out at the Mbolet fish farm in Lambaréné in Gabon in order to evaluate the growth and reproductive performance of these two species. Methods: For this purpose, 226 fish (113 of T. cabrae with an average weight of 30.55±9.5 g and 113 O. schwebischi with an average weight of 20.64±10.5 g), were distributed in four 6 m2 tanks with two replicates per species for the growing phase which lasted 60 days. For the reproductive phase, 42 selected mature fish, including 6 males and 36 females of each species, were placed in six 2 m2 ponds with three replicates per species for 78 days. Result: The survival rate, the number of reproductions per species and the absolute, relative and system productivities were determined. It was found that the average weight gain, daily individual growth and specific growth rate were significantly (p less than 0.05) higher in T. cabrae, 48.1±5.51 g, 0.8±0.092 g/day and 1.57±0.066% g/day respectively, than in O. schwebischi, 27.11±9.23 g, 0.45±0.15 g/day and 1.38±0.051% g/day respectively. At the end of reproduction, the absolute productivity of T. cabrae (234.75±24.71 larvae/female/egg-laying) was significantly higher (p less than 0.05) than that of O. schwebichi (104.68±46.64 larvae/female/laying). System productivity was significantly higher (p less than 0.05) in O. schwebichi (11.34±2.29 larvae/m2/day) compared to that of T. cabrae (4.12±1.73 larvae/m2/day). Thus, on a fish farm, the use of these species may be possible.

Influence of three cage shapes viz (i) rectangular ii) square, and (iii) circular on growth and production of Mystus cavasius (local name: gulsha) was studied in earthen pond conditions for a period of 120 days. Each of nine cages, which were made of polyethylene nets, had same internal area (1.80 m3) and stocked with M. cavasius fry at the rate of 300 m-3, following a completely randomized design. Fishes were fed with a commercial floating pellet feed (Mega 002) initially at the rate of 25% of average body weight, with a gradual reduction to 8%. Significantly higher (P<0.05) average weight gain (AWG) of 13.49 ± 0.14 g, with specific growth rate (SGR) of 1.87% day-1, and the survival rate of 89.41% were recorded for gulsha reared in the circular cage compared to the other shapes. Rectangular and square cages resulted in a similar (P>0.05) AWG of 10.29 ± 0.10 and 10.43 ± 0.25 g with survival rate of 80 and 83.61%, respectively. A significantly higher (P<0.05) average total production of 4.05 ± 0.21 kg/m3 was obtained with circular cage compared to a similar production of 2.72 ± 0.28 and 3.08 ±0.29 kg/m3 (P>0.05) in rectangular and square cages, respectively. In case of lengthweight relationship (LWR), the coefficient of determination values (r2) was 0.86, 0.90, and 0.85 in square, circular and rectangular cages, respectively indicating a good linear regression between length and weight in circular cages than square and rectangular cages. Taken together, these results indicate that circular cage is the best for growth, survival and production of gulsha culture in pond condition. Ann. Bangladesh Agric. (2020) 24(2): 59-68

The study was conducted to evaluate growth, survivability, and proximate composition of Lizaparsia at different salinities to adopt as a potential aquaculture species in salinity intruded coastal areas ofBangladesh. The experiment was carried out at laboratory conditions in rectangular tanks (25 L) with fivedifferent salinities viz. 0, 5, 10, 15 and 20 ppt correspondingly considered as T1(control), T2, T3, T4 andT5. Fingerlings were collected from the Pashur river and stocked at 10 individual/25L tank. After 90 days ofculture period, growth was found significantly different among the treatments. Average weight gain washighest inT2 (1.76±0.19) and lowest inT5 (0.91±0.15). Interestingly survival rate was found 100(%) in alltreatment. Specific growth rate was 0.829±0.10, 1.162±0.14, 0.744±0.2, 0.736±0.10 and 0.605±0.15respectively in T1, T2, T3, T4 and T5. Average daily gain was found higher in T1 (0.059± 0.006g/d),compared to other treatment. The average food conversion ratios were 0.78±0.06, 1±0.00, 0.69±0.06,0.78±0.22 and 1.035±0.25 in T1, T2, T3, T4 and T5 in five tanks, respectively. Better water qualityparameters were observed in T2. The temperature ranged from 28-30.3ºC, pH from 7.21-7.64, DO from5.01-5.68 ppm, hardness from 184.55-237.65mg/l and total ammonia nitrogen (TAN) ranged from 0.52-0.85mg/l. No significant change was observed in the proximate composition of fish reared at different salinities.Finally, it could be concluded that L. parsia can tolerate a wide range of salinity and can be cultured even infreshwater, thus might be a potential species for coastal aquaculture.

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

Abstract This study investigated the effects on survival, growth performance and water quality of algae, yeast and photosynthetic bacteria as diets for larval and immature/mature Streptocephalus sirindhornae. Survival of the larvae fed with the alga Chlorella vulgaris and the photosynthetic bacterium Rhodopseudomonas faecalis for 5 days was higher than 80%, while those fed with the yeast Saccharomyces cerevisiae was 4.4%. After feeding the 6-day-old fairy shrimp until they reached 30 days of age, those fed with bacteria showed the highest survival and growth rate. Ammonia, nitrate and nitrite concentrations in the water treated with R. faecalis were the lowest. The highest ammonia concentration, the lowest dissolved oxygen, and excessive turbidity were found in the yeast treatment. Frequent water replacement could not overcome this, which resulted in the low survival rate. Utilization of photosynthetic bacteria in fairy shrimp culture is for the first time reported herein, and the disadvantages of using yeast in S. sirindhornae cultivation are discussed.

<p>The use of antibiotics for controlling of luminous vibriosis caused by <em>Vibrio harveyi</em> is restricted now, because it induces antibiotic-resistant bacteria and leave residue in shrimp’s body. An alternative solution that can be done to treat the disease is by using applications of probiotic, prebiotic, and synbiotic. The aim of this research was to examine the effect of probiotic, prebiotic, and synbiotic on the survival rate and growth of Pacific white shrimp against <em>V. harveyi</em> infection. Feed as a treatment was supplemented with probiotic 1%, prebiotic 2%, and probiotic 1%+prebiotic 2% (synbiotic). Shrimps feed without supplementation of probiotic and prebiotic was used as a control treatment. The shrimps were maintainedin the aquarium (60×30×35 cm<sup>3</sup>) with a density of 40 shrimps/40 L and an average weight of 0.4±0.1 g. After 30 days of feeding treatment, the shrimp was challenged by immersion method with <em>V. harveyi</em> solution containing 10<sup>6</sup> CFU/mL. The results showed that before challenge, synbiotic feed treated shrimp has a growth rate (5.89%), feed conversionrate (1.21), and a high survival rate (80%). After challenge, survival rate (83.33%) of shrimp fed diet supplemented with synbiotic was higher than prebiotic (51.67%) and positive control (31.67%).</p> <p>Keywords: probiotic, prebiotic, synbiotic, <em>Vibrio harveyi</em>,Pacific white shrimp</p>

Stunting children need food intake with higher protein and essential amino acids such as lysine and leucine than normal children. Red Beans (Phaseolus Vulgaris L.) and Green Beans (Phaseolus Radiatus L.) have protein content, respectively 22.07 ± 0.13% and 19.99 ± 0.07%, and are rich in essential amino acids lysine and leucine needed by a stunting child. The Development of food products with high protein concentrations (high protein food) such as isolates/protein concentrates is an important subject that must be done. This study aims to determine the technique of isolating red bean and green bean protein through extraction and deposition methods at isoelectric pH. The research method used is an experimental method with descriptive data analysis. Identification of isoelectric pH of red bean and green bean protein is done through electrophoretic mobility (cm2/Vs) testing on samples that have been conditioned at 3 different depositional pHs namely pH 3.00, 4.00, and 5.00. The results showed the isoelectric pH value of red bean and green bean protein, namely pH 4.56 and pH 4.81 respectively, where the pH had electrophoretic mobility values equal to zero. The process of isolating red bean and green bean protein produces protein powder with a protein content of 79.22 ± 0.06% and 80.69 ± 0.06%, respectively. Based on the weight yield, red bean and green bean protein concentrate powder had a yield of 14.88% and 16.75%, respectively.
