An agar sediment test was developed to evaluate the suitability of organic waste streams from the food industry for recovering nutrients by the aquatic worm Lumbriculus variegatus (Lv). The effects of agar gel, sand, and food quantities in the sediment test on worm growth, reproduction, and water quality were studied. Agar gel addition ameliorated growth conditions by reducing food hydrolysis a...

A small assemblage of sieved fish remains was analysed from a medieval site on Lindisfarne. Haddock, cod and whiting were the most commonly consumed species, with small numbers of other taxa recovered, including herring and flatfish. Most were probably caught in local inshore or coastal waters, and most were only of moderate size. It is likely the remains include gutting and processing waste (i...

Aquaponics is the combination of aquaculture (fish) and hydroponic cultivation of plants. This review examines fish welfare in relation to rearing water quality, fish feed and fish waste and faeces to develop a sustainable aquaponic system where the co-cultured organisms, fish, bacteria in biofilters and plants, should be considered holistically in all aquaponics operations. Water quality param...

Increasing human population and reliance on aquaculture for seafood will lead to expansion of the industry in the open ocean. To guide environmentally sustainable expansion, coastal stakeholders require tools to evaluate the risks that marine aquaculture poses and to craft science-based policies and practices which safeguard marine ecosystems. We summarized current knowledge regarding dissolved...

Demand of gelatin for food and pharmaceutical application is increasing because it is one of the most widely used food ingredients. Fish gelatin represents one of the important types of gelatin from other sources other than mammalian gelatins and it may thus be considered as an alternative to mammalian gelatin for use in various food and pharmaceutical applications. The main objective of the st...

Fluorescent in situ hybridization (FISH) using 16S and 23S rRNA-targeted probes together with construction of an archaeal 16S ribosomal DNA (rDNA) clone library was used to characterize the microbial populations of an anaerobic baffled reactor successfully treating industrial dye waste. Wastewater produced during the manufacture of food dyes containing several different azo and other dye compou...

The study was conducted at Pig farm of AICRP on Pigs, Livestock farm, Adhartal, College of Veterinary Science & A.H., Jabalpur (M.P.) for a period of three months. A total of 36 Large White Yorkshire crosses (LWY X Desi) were randomly assigned to six different groups and diets were formulated as per ICAR (1998) standard. All the diets were isoproteinous except group-6, which was formulated as p...

Management of ammonia, the primary waste product fish, is critical to fish health, especially in intensive systems. At low concentrations, ammonia causes stress and damages gills other tissues. Fish exposed levels over time are more susceptible bacterial infections, have poor growth, do not tolerate routine handling well. higher it will kill fish. Many unexplained production losses likely been ...
