Fish Pond Construction and Management

INTRODUCTIONAquaculture is one of the fastest growing food producing sectors in Agriculture and fish is among the most traded food commodities world-wide accounting for 17 per cent of global intake of animal protein (Food and Agricultural Organization, 2014).  Fish is an aquatic and a source of high-quality animal protein that could be harvested from capture or culture fishery (Olele et al., 2008). Fisheries expert needs a medium where they can culture fish in a confined and contr...

Aquatic ecological survey

AQUATIC ECOLOGICAL  SURVEY             INTRODUCTION An aquatic ecological survey can be referred to as the backbone of Fisheries, and the process of planning can be referred to as a survey, according to a popular saying “he who fails to plan, plan to fail”. The aquatic ecological survey deals with proper planning in both capture and culture fisheries; planning (survey) in capture fisheries involve the use of a sophisticated instrument to check the aquatic res...

IMPACT OF NYPA PALM (Nypa fruticans Wurmb) AND MANGROVES ON THE PLANKTON AND BENTHIC COMMUNITIES OF THE RIVER ANDONI, NIGERIA.

ABSTRACT The impact of Nypa fruticans (Wurmb) and mangroves on the plankton and benthic communities of Andoni river was carried out between January and August, 2017. Four stations were chosen based on Nypa palm and native mangrove species’ presence and absence. Water quality parameters include; pH 6.99±0.16, Temperature 28.20±0.050C, D.O 4.71±0.18mg/L, Conductivity 19.52±0.20µm/s, Salinity 10.76±0.07ppt, TDS 13.45±0.27ppt.  Mean values of the physico-chemical param...

INTRASPECIFIC HYBRIDIZATION AND RECIPROCAL CROSS BETWEEN CULTURED AND WILD Clarias gariepinus; AND EVALUATION OF THEIR PROGENIES

AbstractStudies of intraspecific hybridization and reciprocal cross between cultured and wild Clarias gariepinus and evaluation of their progenies was carried out, with aim of evaluating the progenies of the crosses hatchability, survival, growth etc. Pure strains of cultured and wild Clarias gariepinus broodstock were used. Incubation, hatching, and post hatching activities were monitored in 50 litres plastic bowls. Cultured Male Clarias gariepinus (CCG♂) x Wild Female ...

Proximate and Macro Element Composition of Four Fish Species from Lower River Benue Makurdi Benue State Nigeria

A study was conducted on four fresh water fish species: Protopterus annectens, Labeo coubie, Auchenoglanis occidentalis and Mormyrus rume from lower river Benue, Makurdi to determine the proximate and macro elements composition of these fish species from lower river Benue Makurdi. A total of 600 fish samples were collected, 50 samples from each species for the period of three months. Fish samples were collected and transported to the University of Agriculture Makurdi, Department of Fis...

Determination of heavy metals in water and Clariasgariepinus from River Ngadda

Abstract  Water and fish samples were collected monthly from each of the four sampling Sites from August to September 2019 with the aid plastic bottles, hook and line and a gura trap from river Ngadda, Maiduguri, Borno state. A total of 16 fishes belonging to Clarias garipienus were sampled throughout the sampling periods. One fish from each station was dried before digestion and other was digested in its fresh form. The samples were transported to Soil Science Laboratory, Faculty of Agricul...

Sea Horse: A Case Study

INTRODUCTIONSeahorses (Hippocampus spp.) are among the many genera whose life histories might render them vulnerable to overfishing or other disruptions such as habitat damage. They are generally characterized by a sparse distribution, low mobility, small home ranges, low fecundity, lengthy parental care and mate fidelity (Foster and Vincent 2004). In addition, the male seahorse, rather than the female, becomes pregnant. Indeed, curiosity about this phenomenon explains why currently more is k...

The Micro Nucleus, Haematology and Toxicity effects of Glyphosate-based Herbicide 'Glysate' on post juveniles of African Catfish (Clarias Gariepinus) Burchell 1822

Glyphosate (N-phosphonomethyl glycine) is a broad spectrum systemic herbicide used extensively in weed control. The present study was designed to evaluate the toxicity effect of glyphosate on 300 post juveniles (50g±0.96g; 22cm±0.02) of Clarias gariepinus (Burchell, 1822) after exposure to acute concentration levels of 31, 33, 35, 37 and 39 mg glyphosate/L of clean water. The experiment was completely randomized as each treatment were all replicated thrice. Glyphosate toxicity (96 hr LC50) ...

Molecular Mechanisms of Natural Carotenoid-based Pigmentation of Queen Loach, Botia dario

The genetic basis and expression patterns of key genes are important aspects of study to understandthe colouration. This trait differs between wild and domesticated fish which is a matter of research.Botia dario is an indigenous fish, having ornamental and aesthetic value, which shows faded appearancein terms of colour in domesticated condition than wild. In the present study the carotenoid-fed B. dariowere examined through incorporation of marigold petal meal in the diets at the rate of 5, 1...

APPLICATION OF BIOTECHNOLOGY FOR GENETIC IMPROVEMENT IN FISH FARMING A CASE OF AFRICAN CATFISH Clarias gariepinus

Biotechnology research and development is moving at a very fast rate. In broad terms, Biotechnology can be defined as any technological application that uses biological systems, living organisms or derivatives thereof to make or modify products or processes for specific use. This range from the use of synthetic hormones in induced breeding hybridization, production of monosex, uniparental and polyploid Molecular biology, transgenic fish to gene banking. CHAPTER ONE 1.0    INTRO...

Risk Analysis of Water Quality in Aquaculture. A case study of Ilorin metropolis, Kwara State, Nigeria

Agricultural products were among the primary export commodities together with petroleum products during the pre-independence era which made the Nigerian economy fairly stable then, contributing about 95% of the total Gross Domestic Product (GDP). After independence, there has been a steady and consistent decline in the value of agricultural products such that as at year 2002, it was estimated to be 32% of the nation’s GDP (Gross Domestic Product) which shows that economic growth in Nigeria ...

Morphometric and Meristic features and Length-Weight Relationship as indicators of quality of Brycinus macrolepidotus in Lower River Ogun, Nigeria

ABSTRACTOne Hundred And Eighty samples of True big-scale fish (Brycinus macrolepidotus Valenciennes, 1850) were collected bi-monthly from June  November, 2017, from River Ogun, Nigeria. Total length and body weight of all samples measured and samples were grouped based on length into sizes: juveniles (10-14.9 cm), sub-adults (15.1-19.9 cm), and adults (20.2-26.3 cm). Significant differences (p

PHYTOPLANKTON COMPOSITION IN TWO WATER BODIES OF THE FEDERAL UNIVERSITY OF TECHNOLOGY AKURE, ONDO STATE, NIGERIA

The phytoplanktons found in the Federal University of Technology Akure (FUTA) was studied from April to August 2017 which spanned for 5 months which took place in two sampling sites, the Fisheries and Aquaculture Technology Research Farm pond (FAT pond) was the first sampling station while Crop Science and Pest Management water body was the second sampling water body where samples were collected at different sampling depths ranging between 16-30cm. A hundred and fifty (150cl) of FUTA water sa...

Fish composition and diversity assessment of Apodu reservoir, Malete, Nigeria

The pilot study on fish composition and diversity of Apodu reservoir, Malete, Nigeria was carried outbetween January to May 2017 using cast and gill net. A total number of 3333 fish, comprising 8 familiesand 17 species were recorded. Brycinus nurse were most dominant for the period of study contributing29.31% and Auchenoglanis occidentalis, least abundant made up of 0.03% of total catch. Other familiesand there percentage contribution in the total catch were Mormyridae (34.14%); Cichlidae (15...
