Of even greater significance to the issue of the relevance of the two cited South African papers to assessment of possible benefits to the Batemans area from the closure of surfzone beaches is the following quote from Bennett and Attwood (1991), “Only 2 of the 10 species examined in this study, Argyrosomus hololepidotus and Pomatomus saltatrix, are highly migratory and neither demonstrated any benefits from protection in the reserve”. The last two species names may have been familiar to many of you. Argyrosomus hololepidotus, actually shares the same species name as our mulloway, and Pomatomus saltatrix is the same species as, or an extremely close relative of, our tailor (FishBase 04/2007). Curiously, as it is based on the same data as the 1991 paper, the 1993 Bennett and Attwood paper adds a third species, Umbrina canariensis, to this group and states, “The catch rates of the same three species…did not increase following the proclamation of the marine reserve, because they are migratory”. Why was this key information not mentioned in the ‘Science Paper’ presented as a basis for a marine park in the Batemans region, where migratory species dominate? The primary target species on ocean beaches in the Batemans Marine Park, Australian salmon, bream, flathead, mullet, mulloway, tailor and whiting are migratory, even if not all equally so. Incidentally, these same migratory species are dominant in the estuaries of the Batemans region.
Therefore, the logical conclusion, relevant to the Batemans Marine Park....is that the closure of ocean beaches as included in the Batemans Marine Park will have absolutely no demonstrable benefit, even for the CPUE, let alone the numbers, of the important species on the ocean beaches in the region.
