Satisfaction is one of the most important aspect of relationship marketing as well as the main trigger of positive word-of-mouth which shows that positive word-of-mouth is a sign of successful relationship marketing. So if it is possible to map the antecedents of positive word-of-mouth it is also possible to guideline relationship marketing. Word-of-mouth has been recognized as the least understood marketing strategy but the most effective. Attempts to investigate word-of-mouth behavior have mainly been made in a marketing world untouched by Internet. The possibilities to measure word-of-mouth has historically been low but Internet has a great impact on both the reach of word-of-mouth and enhances the possibility to measure it. Earlier studies are not written with a purpose to find antecedents of word-of-mouth that are operable for managers and are not specifically written with online word-of-mouth on social media in mind. That is what this book contributes with. This book is mainly written for managers in the retail industry. It also contributes with new research findings within the field of relation marketing in general and word-of-mouth on social media particularly.
The present study focused on determination of the relationship between the management factors, control of aquatic weeds, eradication of predatory fish and weeds fish, application of Mohua oil cake, Manuring, fertilization of ponds, sampling, level of stocking density and fish production in scientific fish culture. Isolation of the factors associated with production was also incidental to determining this relationship.
The present investigation has been carried out with the objectives the utilization of sand smelt fish(bassaria) (Atherina hepsetus) which has found in Qarun,s Lake- Fayuom- Egypt by high numbers, small size, low price, unaccepted from consumers and high edible part(71%) for produce fish products (burgers and fingers) high safely, having a good quality and better acceptability with lowering the coast. The substitution material (soybean flour (SF) and minced boiled potatoes (MBP))was used by different levels in this investigation to improved the sensory evaluation of produced fish products. Sensory evaluation was carried out for fried some fish burgers and fingers by different concentration from substitution materials to select the best treatments. Frozen storage at -18 ±1°C for 3 months was carried out on raw selected fish products to study the effect of frozen storage and substitution materials on the quality of these products during storage. It could be recommended that sand smelt fish can be utilization for production of burgers and fingers in a large scale with the addition of (SF)(20%)and(MBP)(15%)to improve quality and to decrease the production coast of final product.

An ideal water condition is a necessity for the survival and good growth of fish since the entire life processes of the fish is wholly dependent on the quality of its environment. These water quality parameters become more critical in intensive culture systems where fish is raised in artificial ponds with reduced self purification capabilities as compared natural systems. Ichthyology (from Greek: ?????, ikhthus, "fish"; and ?????, logos, "study") is the branch of zoology devoted to the study of fishes. This includes skeletal fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). The study of fish dates from the Upper Paleolithic Revolution (with the advent of ''high culture'').Ichthyology is simply the science of studying fishes.
Low and declining soil fertility are among the major factors responsible for the poor productivity of the small scale rainfed crop farming in most of the Ethiopian highlands. Thus, soil characterization and field experiment was conducted to investigate the effects of applied N and P fertilizer rates on grain yield and yield components for triticale (Triticosecale wittmack L.) production on soils of Wabela, around Debretabor area, Amhara National Regional State (ANRS). The experiment involved factorial combinations of four rates of N (0, 23, 46 and 69 kg ha-1) and P (0, 10, 20 and 30 kg ha-1) laid down in RCBD with three replications. The moist soil color of the profile was very dark brown (7.5YR 3/3), at the surface and dark grayish brown (10YR 3/3) at the bottom, with clay loam to clayey texture. The bulk density values varied with depth of the profile from 1.01 g cm-3 at the surface layer to 1.23 g cm-3 at the bottom layer. Soils of the profile indicated that the soil of the site was moderately to slightly acidic in reaction, high to medium in its total N and high in available P from the surface to the subsurface horizons.
Dr. M.K. Ahirwar, The present research work carried under the title, "Effect of pesticides on the blood profile of the fish N.notopterus (Pallas)" is an effort to assess the impact of three pesticides, i.e.,Endrin,Malathion,Parathion and on the health status of commercially important food fish,documented by the change in haematological and biochemical parameters. The study is divided into four sub portions. The first part deals with the water quality analysis during the exposure time. The second part deals with the exposure of Notopterus notopterus (Pallas) to three pesticides. The third portion deals with the investigation of the haemato-biochemical indices of the test fish. The fourth portion deals with the statistical interpretation of the deviation of parameters from the normal blood values.The research work interprets the total setback of fish metabolic activities with special emphasis on hematology and biochemistry, affected by the immunological disturbance of the fish by the test pesticides. Blood analysis is crucial in many fields of ichthyological research and fish farming and in the area of toxicology and environmental monitoring as possible indicator of physiological.

Scope of use 1. The use of black light trapping insects to feed the fish; 2. The use of black light trapping insects to feed chickens ducks and birds; 3. Killing farm pests blacklight; 4. Killing forest pests blacklight. Installation 1. Installed in 30 cm from the surface can be hung on a wire off the central fish pond attracting insects to feed the fish. The trapping insects collected as fish poultry feed. If you have installed in the field land weeds hanging out at the stake requires the installation of solid not side to side. Strong winds rain and rain within one hour do not turn on the lights to use. Do not touch when you turn on the lights. When using hanging installation is prohibited soaked in water. 2. Do not use other light-degree black light fixtures installed in place so as not to affect the application of results. 3.Case blacklight effect of attracting insects and weather conditions and in no rain no wind [or breeze) the lure for higher amounts; during heavy rain or wind rarely lure catches. So. Depending on weather conditions should decide whether to turn on the lights. Under normal circumstances. Nocturnal activity patterns in a variety of insects vary. Thus where conditions should be full night lights.
Fish meal is one of the most expensive ingredients in prepared fish diets. Therefore, we used of unconventional feed such as algae for substitution the high cost feedstuff such fishmeal with support the maximum growth of fish. In addition to the highly content of protein and essential fatty acids of algae, and more suitable for fish diets, algae production rates where high in tropical and subtropical developing countries. A 12-week feeding trail following by a 2-week digestibility trail were conducted with Nile tilapia fingerling , a control diets without micro algae served as a reference from which inclusion levels of 5, 10, 15 and 20% micro algae were investigated by the replacement of fish meal. Generally, it could be noticed that the inclusion of algae levels up to 15% for Nile tilapia fingerlings produced optimum growth performance, feed utilization and efficiency and digestibility coefficient. Also 10 or 15% algae in the diet improved physiological status and reproductive in items of FSH hormones for Nile tilapia. The present study should help shed some light on this micro algae new source for protein in fish diet which highly elements content and improve fish performance.
