Hit and trial method for artificial feed formulation- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Feed formulation is a technique to be learnt and refined by experience. To date numerous descriptions have appeared in nutrition textbooks. The exercise taught over and over again is difficult to comprehend especially by the beginners. The purpose of this article is to describe and share some of this authors experience in teaching and learning feed formulation; mainly for aquatic animal research. Previous descriptions on the subject can be had from New, 1987 ad Houser and Akiyama 1997 among which New 1987 describes the subject with a lay man in mind. Here again, the emphasis is to describe the technique in the simplest way by which it is presumed that, beginners in the subject of aquatic animal nutrition shall be benefite

Aquatic feed extrusion technology- an update

This article, compiled from various sources for teaching postgraduate students in mariculture, is an attempt to provide a deeper understanding in aquatic feed extrusion technology, which would be of use to current and potential users of extrusion equipment. Extrusion today is also seen as a cheaper alternative to conventional animal protein production which requires investment in crores of rupees in the Indian context

Supplementary feeding in aquaculture

Farming of fish scientifically requires adequate basic knowledge regarding stocking of fingerlings and providing them with requisite environment and feeding. In order to achieve production at a viable level certain fundamental aspects of fish nutrition and on-farm fish feed production should be followed

Marine fish nutrition, feed formulation, feed production and feeding

Feeding rates, feeding frequency and time of feeding are all important factors to be considered in feeding of the fish. As a general rule of the thumb most of the vertebrates including fish consume 2.5 to 3.0% of the body weight in dry matter. Feeding rates and frequencies are related to fish growth. Small larval fish and fry need to be fed a high protein diet frequently and usually in excess. When fishes grow bigger, feeding rates and frequencies should be lowered. Feeding fish is a labour intensive activity and feeding frequency has to be programmed in such a way that it is economically viable

Blending of ingredients in aquafeed formulation the 'Excel' way Tips to farmers/farm managers

Feed formulation is a technique to be learnt and refined by experience. To date numerous descriptions have appeared on the topic in nutrition textbooks. The exercise, even when taught over and over again, is difficult to cornprehend especially by the beginners

Nutritional requirements of broodstock, larvae and juveniles of finfish- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Finfish culture in India is prominent only in the fresh water aquaculture. In the marine and brackishwater sectors only asian seabass (Lates calcarifer) has met with success. Farming of this fish on a commercial scale is still not a reality in India. Technological gaps, and low rate of return when compared with shrimp culture. In this backdrop, the purpose of this article is to review the status of knowledge regarding the nutritional requirements of marine finfish broodstock, larvae and juveniles

Biodiversity, Biotechnology and Biomimicry

This write up is an attempt to collate information on biodiversity and biotechnology interactions and inter relationships in general and examine the status of benefit sharing mechanisms in place when marine biodiversity is used in development of products and services. Additionally, the less known `biomimicry’ which draws inspiration from nature for development of products and services is also introduced with examples

WTO agreements and quality concerns in Indian Fisheries

WTO agreements are legal ground rules of international commerce. As several facets of WTO agreements are discussed in this short course this paper will be a snapshot of Sanitary and Phytosanitary Agreement popularly known as SPSA which is a non-tariff barrier in international trade. The Agreement on the Application of Sanitary and Phytosanitary measures sets out the basic rules for food safety and animal and plant health standards. Safe and hygienic food is preferred anywhere in the world. More so in the northern world where advances in science have increased the level of awareness regarding the health ailments caused due to consumption of unsafe food. This has lead to development of food safety standards in these countries. Not only do these countries adopt these standards but also expect other countries to follow them giving rise to a plethora of issues. The general nature of such food standards can be said to be (1) a growing use of risk analysis (2) treatment of public health as a primary goal of food safety regulations (3) emphasis on a farm-to-fork approach in addressing food safety hazards (3) adoption of HACCP for microbial quality control (4) emergence of newer and extensive regulations to handle newly identified hazards

A preliminary study of the effect of mantis shrimp as an ingredient in Penaeus indicus postlarval diets

The apparent digestibility (Da) of five diets, incorporated with mantis shrimp at levels of to, 15, 20, 25 and 30% was determined for Penaeus indicus postlarvae (initial weight ranging from 0.087-0.106 g). Oa for crude protein ranged from 61.97 to 92.76% showing a significant increase with increase in the level of mantis shrimp upto 25% in the diet and was higher than the control value of 66.09 (P > 0.05). Crude fat digestibility ranged from 52.26 to 89.57% also showing an increase upto 25% incorporation of mantis shrimp
