This study was conducted to assess the procedure of fish feed production, analysis of nutritive value of feeds and its effect on growth of fish in selected fish farms. Five fish feed mills and fifteen fish farmers were randomly selected from Mymensingh district. Fish feeds were used by fifteen farmers among every three farmers used the feed of each mill. These feed Mills collect their Saudi Bangla and ACME fish feed are more preferable to the farmer due to higher protein and lipid content resulting more fish production. In this experiment, Saudi-Bangla fish feed mill (3843 Kg/ha/yr), Sunny fish feed mill (3761 Kg/ha/yr), Shushama fish feed mill (3581 Kg/ha/yr), Al-momen fish feed mill (3669 Kg/ha/yr), ACME fish feed mill (3796 Kg/ha/yr) was produce fish. Capital cost, operating cost, depreciation cost, total cost, revenue income and net profit were calculated and evaluated during the experimental period. In this study, those feed mills production capacity was 45000 ton/yr Saudi-Bangla fish feed mill, 45000 ton/yr Sunny fish feed mill, 35000 ton/yr Shushomo fish feed mill, 35000 ton/yr Al-momen fish feed mill,15000 ton/yr ACME fish feed mill. The fish production mainly carps and pangus were highly occurs chronologically Saudi-Bangla, ACME fish feed, Sunny fish feed, Al-momen fish feed, Shushama fish feed mill, respectively. Among those the nutritive value of Saudi-Bangla fish feed was the best than other fish feed.Res. Agric., Livest. Fish.2(2): 353-362, August 2015

The experiment was carried out under three treatments each with two replications. Fish population density was 80 fish per decimal (silver carp 32, tilapia 32 and mrigal 16) under treatment-1, 120 fish per decimal (silver carp 48, tilapia 48 and mrigal 24) under treatment-2 and 160 fish per decimal (silver carp 64, tilapia 64 and mrigal 32) under treatment-3. The average initial length and weight of the fingerlings of silver carp, tilapia and mrigal were 7.49, 5.12, and 5.56 cm and 8.00, 2.00 and 1.50 g respectively. The ponds were fertilized fortnightly with cowdung, urea and TSP (triple super phosphate) at the rates of 5 kg, 60 g, and 90 g per decimal, respectively. During the experimental period, the range of water temperature (30.20 to 32.90°C), transparency (28 to 38 cm), dissolved oxygen (8.20 to 10.60 mg/L), pH (6.90 to 7.90), total alkalinity (92.00 to 127.00 mg/L), free CO2 (1.00 to 1.60 mg/L), phosphate-phosphorus (1.00 to 1.90 mg/L), and nitrate-nitrogen (1.90 to 3.90 mg/L) were within the productive range and more or less similar in all the ponds under three treatments. There were 25 genera of phytoplankton under five major groups and 10 genera of zooplankton under three major groups in the experimental ponds. The calculated net fish production of the ponds under treatment-1 was 2.62 ton/ha/yr and that of the ponds under treatment-2 was 4.42 ton/ha/yr and that of the ponds under treatment-3 was 5.18 ton/ha/yr. The net fish production under treatment-2 and treatment -3 were 195.58% and 229.20% higher than that of treatment-1, taking net fish production under treatment-1 for 100%. According to profit-cost analysis the ratios of net profit and total cost under treatments 1, 2, and 3 were 1:0.25, 1:0.45, and 1:0.44. According to growth and production treatment-3 is the best, and according to the profit-cost analysis, treatment-2 (ratio 1:0.45) is the best but it is almost same to that of treatment-3. So, the population density of 160 fish per decimal (under treatment-3) might be considered best. It seems that proper determination of stocking density of different fishes in polyculture is very important to increase fish production.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16566Progress.

The experiment was conducted to determine the effect of population density on growth and production of Tilapia (monosex GIFT tilapia) in monoculture system for a period of 110 days. The experiment was carried out in six earthen ponds, which were situated in the Bangladesh Agricultural University Campus, Mymensingh. The experiment was carried out under three treatments each with two replications. Fish population density was 200 fish per decimal under treatment-I, 400 fish per decimal under treatment-II and 600 fish per decimal under treatment-III. In the ponds supplementary feed of wheat bran and rice bran mixture were used daily at the rate of 46 g, 92 g and 136 g per decimal under treatment-I, II, and III, respectively. The average initial length and weight of tilapia were 4.63 cm and 2.82 g respectively. The ponds were fertilized fortnightly with urea and TSP at the rates of 60 g and 90 g, respectively. During experimental period, the ranges of water temperature (25.82 to 29.80 ºC), transparency (28.00 to 38.00 cm), dissolved oxygen (5.50 to 8.30 mg/L), pH (7.00 to 7.90), total alkalinity (130.00 to 200.00 mg/L), free CO2 (2.00 to 6.00 mg/L), phosphate-phosphorus (1.20 to 2.30 mg/L), and nitrate-nitrogen (3.20 to 4.00 mg/L) were within the productive range and more or less similar in all the ponds under three treatments. There were 25 genera of phytoplankton under five major groups and 10 genera of zooplankton under three major groups in the experimental ponds. Mean survival rate of fish under treatment-I, treatment-II, and treatment-III were 82.75%, 77.12% and 74.33% respectively. The calculated net fish production under treatment-I was 6.75 ton/ha/yr and that of the ponds under treatment-II was 10.26 ton/ha/yr and that of the ponds under treatment-III was 12.15 ton/ha/yr. The net fish production under treatment-II and treatment-III were 152% and 180% higher than that of treatment-I, taking net fish production under treatment-I for 100%. According to profit-cost analysis, the ratios of net profit under treatments I, II, and III were 1:0.44, 1:0.27, and 1:0.09. According to specific growth rate and survival, treatment-I is the best, and according to profit-cost analysis treatment-I (ratio 1:0.44) also the best. So, the population density of 200 fish per decimal (under treatment-I) might be considered the best among the three treatments.Int. J. Agril. Res. Innov. & Tech. 7 (2): 49-56, December, 2017

The aim of the study was to evaluate the quantity, costs and contaminations of the physical losses of products (corn, meals, flours, feeds, and micro ingredients) caused by the maintenance system utilized in equipment of the different stages of a feed production mill. The experiment was conducted in a feed industry with production capacity of 1,000 ton day-1. Firstly, an assessment of the maintenance system used in the feed mill was performed, after the products losses were quantified in the external and internal sectors of the milling steps. Two methods were utilized for loss quantification: per sector and per equipment of the feed industry. Samples of the products were collected in different points of the area evaluated for counting of fungi and salmonella colonies, insects and mites. The results showed that a large number of maintenances were not performed within the programmed period, up to 70%. In addition, the equipment maintenance system utilized in the feed milling significantly influenced product losses, reaching 120 kg and costs of US$ 38 per hour worked. The microbiological analysis presented a high contamination index by fungi and salmonellas sp. (7,4 x 104 CFU g-1) in corn grain.

Women play a major role in the accession to food security because of their significant contribution to agriculture. However, very few data exists on women’s contribution to the Cote d’Ivoire fish production. The objective of this study was to evaluate the ability of fish farms owned by women to contribute to the fish production in Cote d'Ivoire. A survey has been conducted on women fish farms characteristics and their production capacity. Only 5.98% of 301 farms belonged to women with a contribution to the total production of 2.89%. They are mostly farmers (44.44%) aged 30 to 60 years (88.89%), native of the regions (66.67%) where they had their farms. Tilapia and catfish are the main species produced with a semi-intensive (83.33%) farming system in pond. The area of production is less than 1 hectare (77.78%). Commercial or farms-made feeds are preferably used as fish feeds. Women-owned farms production is characterized by the tilapia commercial weigh over 300 g (66.67%) and a yield of 1000 kg/ha/year (77.78%). By their choice of production system, feeds and their production capacity, women can contribute to set up a sustainable production environment of farm fish in Cote d'Ivoire.

This research was carried out by visiting total 14 feed mills (8 of them are active, 6 of them are passive) in Diyarbakır province in order to get information on feedstuffs, production, quality, technical capacity, marketing, problems and expectations from public authority. Each feed mill were visited, data were collected by face to face interview, total 34 questions were asked and results were evaluated. According to survey results; total technical capacity of feed mills in Diyarbakır is 388.800 Ton/year, however active capacity is 230.400 Ton/year and their plant utilization is quite low (50.3%), average feed production capacity is 11.9 Ton/hour, daily production is 403 Ton. Feed industrialists primarily indicated that unconscious farmers (85.7%), higher feedstuff price (75%) and unfair competition and unregistered production (62.5%) are the most important problems in the industry. Cereals, wheat bran and cottonseed meal were obtained from South-eastern Anatolia Region, however, other feedstuffs and feed additives were bought from other regions of Turkey. Primary preferences of buying of feedstuffs are: quality of feedstufs 50%, easily obtaining 31%, cheap 19% for feedstuffs. Manufactured feeds were marketed by as follows; 34% distributers, 33% distributors and in factory, 22% directly to farmer and 11% in other ways. As a result, technical facilities were found adequate, feed mill owners are conscious to establish laboratory, they have enough production capacity but, except one of them, they produce only one shift in a day.

Abstract In the past 70 years the world has relied extensively for its energy needs based on hydrocarbons produced significantly offshore. In recent years many installations with fixed platforms and pipelines are reaching the end of their useful life and are required by law to be decommissioned and removed if an approved alternative use cannot be found. This process coincides with focus on decarbonization arising from global warming and climate change. The conventional way of decommissioning is to remove the structure and take it onshore for disposal. Such an activity costs around £28 million for smaller UKCS installations in the Southern North Sea. Possible alternative solutions include their use as a research-leisure complex and artificial reef. Such an approach would have less impact on the environment and it is therefore worthwhile to explore the feasibility of repurposing these decommissioned UKCS platforms. The paper begins by highlighting the background to UKCS offshore decommissioning and farming fish life-cycle. This is followed by a critical review of the three options of total and partial removals and leave-on-site. It is found that repurposing decommissioned platforms for aquaculture farm has not been given sufficient attention and thus offers scope for a project to explore the feasibility of such a solution. Existing offshore fish farming in various countries are examined before using a decision-making matrix to select the most suitable UKCS installation for conversion and this led to using a normally unattended gas platform for the case study. The focus for this paper is on design and operation of an unattended fish farm and its cost benefit analysis. The former covers fish cage selection, capacity calculation, fish handling procedures, fish feed characteristics, feed demand, designing feed logistics and storage system. The processing facilities are layout on two decks and power needs are generated using a hybrid system of diesel and Li-ion battery. The possibility of using renewable sources by connecting to wind energy grids was also considered. For the latter capital and operating expenditure, revenue generated and maintenance costs are estimated before performing net present value prediction of the profitability of the fish farm over 10 years with for example up to 8 cages and three discount rates. The main conclusions derived are: It is technically feasible to convert a decommissioned gas platform to a fish farm and the operation can be economic. However, liability transfer implications in a repurposed offshore decommissioned gas platforms to fish farms were not established to verify the project viability. The conversion of unattended offshore gas platforms in the UKCS to an automated offshore fish farm is a novel solution which has not been implemented in the North Sea before. The work will provide an economic and environmental friendly solution to decommissioning offshore platforms and provide with a possible profitable investment.

Brazilian fish farms presented an accelerated development during the early 90's, mainly because of the increase in fee-fishing operations. To meet the demand of this market, fish production and supply became excessive and, as a consequence, the number of fee-fishing operations, farmers and the final selling price, decreased. This study analyzes the technical aspects, production cost, profitability and economic viability of the production of piauçu (L. macrocephalus) in ponds, based on information from a rural property. Feeding and fingerling costs amount to approximately 47.1% of the total production cost, representing together with the final selling price the most important factor affecting profitability. The payback period was 8.3 years, the liquid present value US$ 291.07, the internal return margin 9%, and the income-outcome ratio was 1.01, which represents an unattractive investment as a projection based on current conditions. The improvement in productive efficiency enhances the economic valuation index, and that the relative magnitude of cost and income are the most important points for the economic viability of the studied farm.

An experiment was carried out on the effects of periphyton on monoculture of Thai sharputi, Puntius gonionotus at the Department of Fisheries Management, Bangladesh Agricultural University, Mymensingh during 7th August to 8th November. In treatment-1 bamboo poles were used as artificial substrate for periphyton production and in treatment-2 there was no artificial substrate (control). Each of the six ponds was stocked with 150 fingerlings of average size 6.41 cm and 3.60 g. The ponds were fertilized fortnightly with manure (cow dung) at a rate of 10 kg decimal-1, urea 60 g decimal-1 and triple super phosphate 90 g decimal-1. During the experimental period, the ranges of physico-chemical parameters viz. air temperature (31.0-35.50C), water temperature (29-320C), water depth (0.56-0.84 m), transparency (32-63 cm), dissolved oxygen (3.5-7.8 mg L-1), pH (6.8-7.9), total alkalinity (44-92 mg L-1), free CO2 (1.5-4.0 mg L-1), phosphate-phosphorus (0.31-1.07 mg L-1) and nitrate-nitrogen (1.12-2.30 mg L-1) were within the productive range and more or less similar in the ponds under treatments-1 and 2. Among the observed biological parameters, there were 35 genera of phytoplankton composed of five groups and 13 genera of zooplankton composed of four groups in the experimental ponds. Thirty three genera under the groups of Bacillariophyceae, Chlorophyceae, Cyanophyceae and Euglenophyceae formed the periphyton on bamboo poles in the experimental ponds. Net fish production of the ponds with periphyton under treatment-1 was about 1.5 times higher than those of the ponds without periphyton (treatment-2). By analysis of variance, it was found that the net fish production of Thai sharputi under treatment-1 was significantly higher than that under treatment-2 (p< 0.05). Finally, it can be concluded that periphyton is one of the preferable food item of Thai sharputi and it is also suggested that growth and production of Thai sharputi can be increased if arrangement is made for periphyton production.
