Comparative morphology of wild, farmed and hatchery-released gilthead sea bream (Sparus aurata) in western Greece

In May 2001, 60,000 individuals of gilthead sea bream (Sparus aurata) fry, originating from a common bloodstock of the Ionian coastal region, were allocated between Papas lagoon and cages of mariculture enterprises located at Western Greece. During the period of November to December 2001, a sample of 531 gilthead sea bream individuals was collected from the lagoon and the cages. The variations in 24 morphomertic...

Food and feeding habits of the African river prawn (Macrobrachium vollenhovenii, Herklots, 1857) in Epe Lagoon, southwest Nigeria

The study investigated the stomach contents of Macrobrachium vollenhovenii from the commercial artisanal catches in Epe Lagoon in Lagos, southwest Nigeria from July to October 2008 and April to May 2009. The stomach analysis was carried out using frequency of occurrence and numeric methods. It was observed that the prawn fed on a variety of plankton species, which included chlorophyta, euglenophyta,...

Digestibility coefficients of processed jackbean meal Cannavalia ensiformis (L.) DC for Nile tilapia, Oreochromis niloticus (Linnaeus, 1758) diets

A study was conducted to determine in-vivo apparent digestibility coefficient of nutrients in processed jackbean meal. Acid Insoluble Ash (AIA) was used as an indicator. The test diets consist of the seed meal replacing soybean meal at 10, 20, 30 and 40% to serve as test diets D10, D20, D30, and D40 respectively. A diet called as diet CTR, without jackbean meal served as control. These diets were fed to...

Effect of the inclusion of a bacterial mix (Streptococcus faecium and Lactobacillus acidophilus), and the yeast (Saccharomyces cerevisiae) on growth, feed utilization and intestinal enzymatic activity of Nile tilapia (Oreochromis niloticus)

This study evaluated the effects of two types of probiotics, a mix of two bacteria and one yeast, on growth performance and intestinal enzyme activity in Nile tilapia. Three diets were formulated containing the optimum protein level (40%) for tilapia fry: one was supplemented at 0.1% with a bacterial mixture containingStreptococcus faecium and Lactobacillus acidophilus; a second was supplemented at 0.1% with...

Toxicity of pawpaw (Carica papaya) seed powder to sharptooth catfish Clarias gariepinus fingerlings and effects on haematological parameters

The mesocarp of pawpaw fruits (Carica papaya) is a delicacy in the Tropics but the seeds are known to contain toxic substances (Carpine, Papain). However, there have been very few studies on the toxicity of these substances to organisms. First part of the present study determines the toxicity of an aqueous...

The status of mangrove mud crab fishery in Kenya, East Africa

Mangrove mud crabs, Scylla sp. are among crustaceans of commercial value along the Kenyan coast and in many mangrove areas in the Western Indian Ocean region. In Kenya the crabs are landed by artisanal fishermen. Rising population in the coastal areas and high demand for the crabs has led to increased pressure on the crabs. The population structure and maturity stages of Scylla serrata from...

Optimum dietary protein levels and protein to energy ratios on growth and survival of juveniles spotted Babylon (Babylonia areolata Link) under the recirculating seawater conditions

A feeding experiment of three dietary protein levels (35, 40 and 45%) and three dietary energy levels (3.8, 4.0 and 4.2 kcal g-1 diet) factorial design with four replicates  was conducted to determine the proper dietary protein and energy levels for the growth and survival of the juveniles spotted babylon Babylonia areolataunder the recirculating seawater conditions. Snails with initial body weight...

Zooplankton-based assessment of the trophic state of a tropical forest river

In this study, we explored the usefulness of zooplankton as a tool for assessing the trophic status of a Nigerian forest river. The river was sampled monthly and investigated for water physico-chemistry and zooplankton community structure using basic statistical measurement of diversity indices to characterize the zooplankton fauna. The trophic status of the river evaluated from the physico-chemical parameters indicates...

Real-time quantitative (PCR) applications to quantify and the expression profiles of heat shock protein (HSP70) genes in Nile tilapia, Oreochromis niloticus (L.) and Oreochromis mossambicus (P.)

Quantitative real-time PCR (qRT-PCR) has already been used to study the expression profiles of heat shock protein (Hsp) genes in Nile tilapia, Oreochromisniloticus (Lineaus, 1752) and Oreochromis mossambicu (Peter, 1983). Young fish were exposed to heat stress for 5.5 h followed by qRT-PCR of Hsp70 mRNA, using tubulin (tub) as a reference gene and flourogenic dyes. Expression of Hsp70 mRNA peaked at...

Reproductive performance, egg and larval quality and egg fatty acid composition of hatchery-reared Spotted Babylon (Babylonia areolata) broodstock fed natural and formulated diets under hatchery conditions

A 120 day feeding trial was conducted to evaluate the reproductive performance, egg and larval quality and egg fatty acid composition in Spotted Babylon (Babylonia areolata) broodstock fed with natural food (fresh meat of carangid fish, Seleroidesleptolepis,) and one of four experimental formulated diets containing 5 or 15% of dietary lipid from either tuna oil or a mixture of tuna oil and soybean oil (6:4) labeled...
