The bluefish, Pomatomus
saltatrix (Linnaeus, 1766), the only representative of the Pomatomidae
family, is a key fishing resource that represents a substantial part of the
landings at RESEX-Mar of Arraial do Cabo-RJ. The spec ...

The study of heavy metals in water and sediment was
carried out in the upper reach of the New Calabar River, Niger Delta region in
Nigeria. Three sampling stations were selected which were
Choba, Ogbogoro and Aluu.
Water and sediment samples were collected and analysed, using the buck
scientific Atomic Absorption/Emission spectrometer
200 A model. Water Physico-chemical parameters were measured i ...

The Recruitment Pattern of Liza falcipinnis from Elechi creek of
Upper Bonny, Niger Delta, Nigeria was studied from (March 2009-January 2010). The pattern showed all year round recruitment
with two peaks (one major and one minor) during the period of the study. The
parameters obtained were L∞ = 19.96, K = 0.40 y ...

Maximum sustainable yield (MSY) is the most
important concept in fisheries resource management. MSY can be established
based on the concept of the density-dependent effect. However, the concept that a density-dependent effect controls
the fluctuation of the population living in the ocean is controversial. This
paper discusses the validity of the density-dependent effect focusing on the
stock-recruitment relationship (SRR). In many ...

The objective of the study was to reduce
post-harvest losses by developing a fish chub using Clarias
gariepinus and to determine the
effect of Monodora myristica (local
nutmeg) and sorbitol on the physical quality, proximate composition and
trimethylamine content of the product. Cooled smoked ...

In order to find an effective immune preparation to control
tilapia streptococcus disease, the Streptococcus agalactiae surface protein serine protease
C5a peptidase (ScpB) was cloned and the recombinant protein was encapsulated in
poly (lactide-co-glycolic acid) (PLGA) microspheres, which wer ...

An assessment of some Heavy Metals in Sediment of Otamiri River, Imo
State, South-Eastern Nigeria was conducted between the months of August to
October, 2015. Water samples were collected from four sampling stations
established along the river channel for 3 months (fortnightly). Physic- chemical
parameters were analyzed following conventional field and standard laboratory
techniques. Temperature range between 24.25℃ - 30.50℃, Hydrogen ion mean
concentration value of 7.01 ± 0.19 ppm was obtained,...

As the global population increases, demand for food, most especially
protein, will increase. The increasing production
from agriculture, including forestry and fisheries, has, however, contributed
significantly to global food security but most often at the expense of
environmental deterioration. Integrated aquaculture (IA) can guarantee and
sustain adequate food security in environmentally friendly manner. Integrated
fish farming is a diversified and coordinated way of farming with fish as the
m...

In the present study, a survey was done to mainly
focus on piscine diversity in the wetlands of Coimbatore District, because it is
considered as a good indicator of balanced and healthy ecosystem. The present survey
study has shown that selected sampling site (Perur, Muthanankulam and Kurichi)
wetlands supported 40 species of fishes belonging to 4 orders 07 family and 21 species
during the study. Among the species, Cyprinidae was the most dominant group representing
08 species, Siluridae with 03...

Length-weight relationship is an essential biological parameter needed to
appreciate the suitability of the environment for any fish species. That is why
many fishery biological studies give an importance to it. The relationships
between total length and body depth and girth are very important in estimating
the allowable catch and appropriate mesh size to be used in a fishery. Length-weight
and some morphometric relationships (depth-total length, girth-total length and
dorsal fin length and anal...
