Oreochromis niloticus (35.5 ± 0.24 g) were randomly stocked at the following densities: 80 fish/m3 (F80), 120 fish/m3 (F120), and 160 fish/m3 (F160) in triplicate. Ammonia, nitrate, nitrite, and CO2 were increased significantly as density increased and dissolved oxygen decreased (P < 0.05). A significantly increased weight gain, specific growth rate, growth efficiency, and protein efficiency ratio were recorded in F80 groups compared to F160 groups, whereas feed conversion ratio was decreased. Protease, amylase, and lipase activities were significantly lower as fish density increased. An improved (P < 0.05) red blood cell count, hemoglobin, and hematocrit were found in F160 groups. A considerably higher level of glucose, cortisol, triglycerides, total cholesterol, alanine, and aspartate aminotransferase were recorded in high-density tanks (P < 0.05). The crude lipid and carbohydrate contents were significantly lower in F160 groups. Hence, the outcomes of the present study indicated that stocking density 80 fish per m3 would be appropriate as it promotes the growth and health status of Nile tilapia cultured in RAS.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41722701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study also identified the major constraints affecting the development of aquaculture and suggested possible interventions for further research and extension services in the study areas. Data was collected from a total of 300 households and presented as descriptive statistics. The present study showed that 96.7% of the total respondents were used river and stream water to fill their ponds. The study also showed that 93.4% of fish farmers were involved in pond-based aquaculture production. Relatively higher numbers of fish farmers found in Gedeo Zone (95.5%) were involved in pond-based aquaculture than found in Sidama Region (87.2%). Across the study areas, 34.7% of the respondents reported that fish production trend is increasing. The study also showed that 72.7% of the respondents reported that the absence of technologies was the first ranked constraint affecting the development of small-scale aquaculture. In conclusion, the trend of small-scale aquaculture production is increasing due to the availability of potential water resources and good types of soil used for pond-based aquaculture development. The absence of aquaculture technologies, and lack of quality fingerlings are the most prominent constrains affecting the development of aquaculture. Therefore, capacity building through training, extension, and advanced education to fish rearing households and researchers and allocation resources are crucial for successful development of aquaculture in the study areas.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44905607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basal diet was designed to contain 30% protein and 6% lipid. The primary protein source of the basal diet included: 5% fishmeal, 37% soybean, and 5% gelatin. The intact protein was incrementally reduced to produce diets with 28%, 26%, 24%, and 22% protein. In a second series of diets, CAA were supplemented to the reduced protein diets to return the diets to 30% crude protein. Thus, producing a series of diets containing 30% protein with 2%, 4%, 6%, and 8% crystalline amino acids. The trial was conducted twice to confirm results. Data within treatments for both trials were variable, resulting in limited statistical differences. From a biological standpoint, percentage weight gain (PWG) and mean final weight (MFW) appeared to decrease with intact protein level of the diet (R2 value [PWG], trial 1: 0.30, trial 2: 0.34, R2 value, [MFW] trial 1: 0.44, trial 2: 0.38). None of the diets with supplemented CAA appeared to have reached the same MFW or PWG as the basal diet. Another trial was run using a fishmeal-based diet (30% CP), which in theory should be replete in all essential amino acids, and a soybean meal-based diet at two different protein levels (30% and 35% CP). The soybean meal-based diets were supplemented with essential CAA in one set and only methionine in another to reach the same level as a percent protein, compared to the fishmeal-based diet. No significant differences were observed between the diets in terms of PWG. However, the fishmeal-based diet seemed to outperform most of the other diets in terms of protein retention efficiency. Based on the results of these trials, it is questionable whether CAA are sufficiently utilized by shrimp.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47204114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three isonitrogenous (300 g kg−1 crude protein) and isolipidic (55 g kg−1 crude lipid) diets containing carbohydrate sources (corn, broken rice or sorghum) were formulated. Each experimental diet was fed to five groups (25 fish, 12.13 ± 0.09 g, per tank), three times a day during a period of 60 days. Cholesterol was lower in sorghum, and high density lipoproteins and hepatic glycogen were higher with the use of sorghum (P < .05). Low density lipoprotein was higher when feeding with corn. Plasma glucose was higher in treatments with broken rice and corn. Sorghum led to lower values of hepatosomatic, visceral and digestive somatic indexes. Enzymes activities (amylase, lipase, maltase) reduced their activities in fish fed with sorghum. Broken rice resulted in higher lipid content and lipid retention coefficient in whole fish. The data suggest that the growth of Piaractus mesopotamicus and digestibility are not affected by the chemical composition of starch from the carbohydrate sources tested, however, different metabolic behaviors occurred, either from the starch content in diet, the starch composition of each ingredient, or the pro-nutritional effect of sorghum.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49288809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The harvesting of wild fish to supply the market has a significant environmental impact. The effect of photoperiod and temperature on ovarian maturation is assessed to evaluate its potential to manipulate reproduction. Fish were exposed to three treatments (in triplicate): (light hours: L/temperature: °C) 12 L/20°C, 24 L/20-25°C, and 9.8–13.3 L/20-25°C. Gonadosomatic index (GSI), plasma estradiol (E2), oocyte diameter, and vitellogenic oocyte percentage were estimated. Mean GSI, E2 values, oocyte diameter, and percentage were significantly higher in 9.8–13.3 L/20-25°C than in the other treatments, indicating ovarian maturation. In turn, these values were minimal in the 24 L/20-25°C treatment, revealing ovarian regression. These results suggest that in C. interruptus, the photoperiod is the primary driver of gonadal maturation and the temperature plays a secondary role. This study demonstrated that manipulation of ovarian development is possible through the design of photothermal regimes based on the winter-spring transition.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41762897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
