At this stage, it is not clear why

At this stage, it is not clear why in the analysis of Planque and Fredou (1999)
the relationship of recruitment to temperature seems to be slightly negative in
the northern cod stocks. Is it possible that in this heavily exploited stock recruitment
has been more affected by removal of the spawning biomass than by environmental
factors?

Pada tahap ini, tidak jelas mengapa dalam analisis Planque dan Fredou (1999)
hubungan perekrutan suhu tampaknya sedikit negatif di
saham cod utara. Apakah mungkin bahwa dalam perekrutan saham sangat dieksploitasi ini
telah lebih dipengaruhi oleh penghapusan biomassa pemijahan daripada lingkungan
faktor?
