An 8-week feeding trial was conducted to determine dietary fiber utilization level in Barbonymus schwanenfeldii fry based on the growth, feed efficiency and nutrient utilization. Intestinal α-amylase activity and liver and intestinal histology were used to evaluate the growth performance of fish. Five isonitrogenous (48% crude protein) and isocalor...

A 56-day feeding trial was conducted to evaluate the effects of native and pregelatinized starches on feed quality, digestibility, growth, nutrient utilization, intestinal α-amylase activity, plasma biochemical parameters and liver and intestine histology of Barbonymus schwanenfeldii juveniles. Six isonitrogenous and isocaloric diets were prepared...

Aquafeeds with optimum digestible starch levels provide nutritional, economic, and environmental benefits in aquaculture. Tinfoil barb juveniles can optimally utilize 19.25% dietary corn starch, but their ability to use commonly available starch sources has not been explored. This study aimed to compare the effects of starch sources on fish growth,...

Fish exhibit vast inter-and intra-specific variations for the utilization of dietary carbohydrates based on their digestive physiology. Aquafeeds consisted of optimum levels of dietary starch improve the growth and feed efficiency in most freshwater farmed fish species. The shape, size, and amylose and amylopectin contents of the starch granules of...

Growth and general wellbeing of fish are often deduced by its length-weight relationship (LWR) and condition factor. Intraspecific variation in growth patterns of fish raised under the controlled environment is substantially influenced by their nutritional status. Dietary carbohydrate as one of the cheapest macronutrients is prominently investigate...

High cost of fishmeal used in broiler diets often challenges profit margin of boiler production. Hence, researchers are more focused on evaluating alternative animal protein sources to cut down the feed cost which accounts for 60 to 75% of the total production cost. In this context, sprat-head meal (SHM) was studied to partially replace fishmeal in...

The present study was carried out to developed Palmyrah Fruit Pulp (PFP) added yoghurt and investigates the effects of physico-chemical attributes of yoghurt during storage. Result of this study revealed that the physico-chemical attributes like ash, dry matter, total sugar, reducing sugar, pH and titratable acidity were significantly (p<0.05) chan...

Study was conducted to assess the relationship of environmental and animal (cow) factors on conception rate at the time of insemination onSahiwal cattle and their crosses inBatticaloa District (dry zone) of Sri Lanka. Breedable female Sahiwal cattle and their crosses (204) were used in this study. All cows were artificially inseminated (AI) and sel...

Successful shrimp aquaculture depends on the quality of culture environment. Although shrimp farming in Batticaloa had been practiced since the latter part of 2002, there is a lack of information available on the culture environment. Therefore, a study was conducted to analyze the water quality parameters and growth performance of farmed Penaeus mo...

Nowadays demand for edible bivalves had increased in Sri Lanka, especially in hotel industries. Hence a study was conducted to analyse the potential of Thampalakamam bay of Sri Lanka for the development of edible bivalve industry. Pre-tested questionnaire was used to collect the information. The study shows that a majority of the bivalve fishers en...

Fishermen depend on the indigenous knowledge for their fishing activities. Studying about the indigenous knowledge used by the bivalve fishers helps to understand the bivalve fishery and facilitate future researches and extension services. Thampalakamam bay is a potential area for the production of edible bivalves in Trincomalee district. However d...

Kinniya is one of the 11 Divisional Secretary Divisions in Trincomalee District populated with 96% of Muslims. Traditionally, the livelihoods of about 450 fishers in Kinniya are supported by Thampalakamam Bay. However, the socio-economic conditions of these fishers have been observed to be threatened by anthropogenic effects, seasonality in fish pr...

Kinniya is one of the 11 Divisional Secretary Divisions in Trincomalee district populated with more than 96% of Muslims. Geographical location of Kinniya around Thampalakamam bay and Koddyar bay provides a lucrative livelihood for ⅓rd of its total population via marine fisheries. Thampalakamam bay is a brackish water resource with diversified aquat...
