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﹣1, C = 0, WP = 0, to = 0. The C indicates the amplitude of seasonal growth oscillations (that is, the magnitude of the growth patterns) and has values ranging from 0 to 1.0. Winter…

A Preliminary Study of Growth Pattern, Condition Factor and Population Structure of Sicklefin Mullet, Liza falcipinnis (Valenciennes, 1836) in the New Calabar River, Nigeria
TLDR
The result of length weight relationship revealed negative allometric growth pattern and the exploitation rate which maximises yield per recruit produced values of Emax was 0.88, which indicated that the species was overfished, revealing the need to regulate fishing activities in the New Calabar River for sustainable exploitation.

Some Biological Aspects of the Sharpnose Mullet Liza saliens (Risso, 1810) in Gorgan Bay-Miankaleh Wildlife Refuge (the Southeast Caspian Sea)
TLDR
Age, growth and reproduction of the sharpnose mullet L. saliens by regular monthly collection throughout one year from April 2002 to March 2003 in Gorgan Bay was investigated, and the absolute fecundity to fish size (length and weight) and age were positively correlated.
Population parameters of Oreochromis leucostictus from Lake Naivasha
Length-frequency data collected from fish landings on Lake Naivasha were used to estimate the growth parameters: total mortality (Z), growth performance index (O’), exploitation rate and recruitment

Summary The fish assemblage of the lower Bonny river of the Niger delta with its adjoining creeks was studied. Local fishing gear was used in the collection of samples, which yielded 25 families

TLDR
Although a general trend was observed in the seasonal yields of fish, with higher yields during low water, the variations were not significant either for the overall annual yields or among sets, the implications in relation to the mode of life of the major fish species and the stability of the fish population are discussed.

TLDR
Each reproductive stock displayed its own life-history characteristics, with significant differences between mean length of reproducing females, growth rate, mean brood size, offspring size, standard fecundity and minimum length at reproduction.

Population parameters of small pelagic fishes caught off Tawi-Tawi, Philippines.
TLDR
The growth parameters derived were found comparable with previous estimates available for the same species from other localities, and fishing mortality and exploitation rate were found to be presently above appropriate levels.
The distribution, abundance and trends in the establishment of the family schilbeidae (osteichthyes: siluriformes) in Lake Kainji, Nigeria
TLDR
The distribution and abundance of the five species of Schilbeidae in Lake Kainji showed that Eutropius niloticus was the most abundant and very common species in the lake while S. mystus had its highest number in the riverine areas of the Lake.

On improving the resolution of the recruitment patterns of fishes
TLDR
It is proposed that the "recruitment pattern" routine of the ELEFAN II program can be modified to allow, in addition to length-frequency data, the use of "restructured" data files, which results in recruitment patterns that have less temporal spread and hence better reflect the actual seasonality of recruitment.
