Marine recreational fishing and the implications of climate change

Marine recreational fishing is popular globally and benefits coastal economies and people's well-being. For some species, it represents a large component of fish landings. Climate change is anticipated to affect recreational fishing in many ways, creating opportunities and challenges. Rising temperatures or changes in storms and waves are expected to impact the availability of fish to recreational fishers, through changes in recruitment, growth and survival. Shifts in distribution are also expected, affecting the location that target species can be caught. Climate change also threatens the safety of fishing. Opportunities may be reduced owing to rougher conditions, and costs may be incurred if gear is lost or damaged in bad weather. However, not all effects are expected to be negative. Where weather conditions change favourably, participation rates could increase, and desirable species may become available in new areas. Drawing on examples from the UK and Australia, we synthesize existing knowledge to develop a conceptual model of climate-driven factors that could impact marine recreational fisheries, in terms of operations, participation and motivation. We uncover the complex pathways of drivers that underpin the recreational sector. Climate changes may have global implications on the behaviour of recreational fishers and on catches and local economies

Phenotypic Characterization of the Bunaji Cattle Breed in Oyo State, Nigeria

Nine body measurements of 859 (401 females and 458 males) Bunaji cattle of various ages (1 - >4 years) were collected over a period of 4 months (July - October) at the Bodija livestock and Akinyele international livestock markets in Ibadan, Oyo state of Nigeria. The parameters measured were head to shoulder (HTS), shoulder to tail drop (STD), body length (BLT), heart girth (HTG), height at withers (HTW), canon circumference (CCR), tail length (TLT), horn length (HLT) and ear length (ELT). Phenotypic traits such as dewlap, coat color, horn type, ear type, hump type and navel flap were also examined by visual assessment. The means and standard deviations obtained for the body measurements were 120.18 ± 7.94, 145.99 ± 14.28, 47.31 ± 6.71, 117.35 ± 12.36 and 37.08 ± 14.11 for HTW, HTG, HTS, STD and HLT respectively. The coefficient of variation of the body dimensions were high ranging from 6.60% for HTW to 39.44% for HLT. Sex of the animal had no significant (p>0.05) effect on the body dimensions. Correlation coefficients for the relationship between body measurements ranged from 0.06 (HTS and STD) to 0.89 (STD and BL) for the males and 0.04 (HTS and STD) to 0.89 (STD and BL) for female. The high and significant relationship (

A comparison of pre and early-laying characteristics of four commercial pullet strains in warm wet climate

This study determined the level of pre-production and production differences between four commercial pullet strains, Lohmann Tradition (LT), Lohmann LSL Classic (LC), Bovans Goldline (BG) and Bovans Nera (BN), bred in Europe but whose eggs were hatched in Nigeria. The study also compared these results with the performance recorded in their management guides. There were significant differences (
