The motality, exploitation rate and recruitment pattern of Callinectes amnicola from Okpoka creek was studied from January-December 2007. Total mortality (Z) value was Z=5.19 yr^(-1), M=1.30 yr^(-1), F=3.89yr^(-1) and exploitation rate (E)= 0.7495. The exploitation rate (E(subscript max)) that gives maximum relative yield-per-recruit was 0.4890. The exploitation rate at which marginal increase occurred in the relative yield-per-recruit was 10% of its value at E=0, whereas (E0.1) was observed to…

GROWTH AND EXPLOITATION STATUS (Channa striata Bloch, 1793) IN LUBUK LAMPAM FLOODPLAINS, SOUTH SUMATERA
TLDR
The Yield per recruit and biomass per recruit models indicated that, the fisheries status of C. striata in Lubuk Lampam floodplains exceed the limit reference point (Fmax), thus stock of this species is indicated being driving down.
The recruitment pattern of Macrobrachium macrobrachion (Herklots, 1851) from Luubara Creek, Ogoni Land, Niger Delta, Nigeria.
TLDR
The recruitment pattern of Macrobrachium macrobrachion from Luubara creek in Ogoni land area of Niger Delta region in Nigeria was studied and showed that there were more females than males in the population and probably this allowed for continuous replacement.

The Mortality, Exploitation Rate and Longevity of Macrobrachium macrobrachion (Herklots, 1851) in Luubara Creek, Ogoni Land, Niger Delta, Nigeria
The mortality, exploitation rate and longevity of Macrobrachium macrobrachion from Luubara in Ogoni land area of Niger Delta, Nigeria was studied for period of two years (January, 2006 - December,
Demographic Structure and Level of Exploitation of the Small Pelagic Pellonula leonensis Boulenger, 1916 (Pisces; Clupeidae) Fishery in the Aghien lagoon, West Africa
TLDR
The exploitation rate obtained was close to E0.1, indicating that the P. leonensis stock is in an optimum state of exploitation, and growth parameters indicated that the asymptotic length has been estimated at 126.84 mm SL.
Growth, Mortality Parameters and Exploitation Rate of West African Ilisha ( Ilisha africana Bloch, 1795, Clupeidae) off Benin Coastal Waters (West Africa): Implications for Management and Conservation
West African Ilisha was the third most abundant species of Clupeidae off Benin coastal waters after Sardinella spp and Ethmalosa frimbriata. The fishing effort of these fisheries increased with a
The Fecundity of Macrobrachium macrobrachion (Herklots, 1851) from Luubara Creek Ogoni Land, Niger Delta, Nigeria
TLDR
The fecundity of Macrobrachium macrobrachion from Luubara creek in Ogoni land axis of the Niger Delta region of Nigeria was studied and a strong correlation exists between the number of eggs and total length of berried females (r = 0.969).
The Fecundity of Brackish River Prawn (Macrobrachium macrobrachion, Herklots, 1851) from Great Kwa River, Obufa Esuk Beach, Calabar, Cross River State, Nigeria
TLDR
The study shows that the fecundity of the prawn was low when compared to other studies and there was high correlation between female body weight, standard length, total length, carapace length and the number of eggs.

TLDR
The exponential relationships were presented for relationships of fecundity in number and weight of egg mass in terms of carapace width and body weight, indicating that the fecundities increased with the size from 4.05 × 105 to 2.44 × 106 eggs.

Biology of the African clupeid Limnothrissa miodon with reference to its small size in artificial lakes
  • B. Marshall
  • Environmental Science
    Reviews in Fish Biology and Fisheries
  • 2004
TLDR
The significance of this phenomenon is that Limnothrissa can maintain a high biomass and productivity in the face of intense predation, and may be of importance to fisheries management because it means that their yield can be greatly increased.
Why do shore crabs not prefer the most profitable mussels?
TLDR
It is suggested that crabs select small crushable mussels to prevent claw wear and tear and risk of claw damage may be of greater importance to a foraging shore crab than energy maximization.
Utilization Of Marsh And Seagrass Habitats By Early Stages Of Callinectes-aapidus - A Latitudinal Perspective
TLDR
The quantity of habitat may be important over small latitudinal scales but other factors could affect population abundances across broad latitudinal distances; factors are reviewed in an attempt to understand regional differences in the patterns of C. sapidus abundance.
The swimming crabs of the genus Callinectes (Decapoda: Portunidae)
TLDR
The genus Callinectes and its 14 species are reevaluated and a fresh look is taken at the component species in order that major areas of study such as fisheries biology, ecology, zoogeography, embryology, and physiology can proceed on a stable nomenclatural basis.
