Profile of a fishery collapse: why mariculture failed to save the large yellow croaker

Introduction 220Methodology 221Ecology and Biology 221Distribution 221Putative geographic stocks 221Reproduction, age and growth 222 AbstractThe large yellow croaker (Larimichthys crocea), endemic to East Asia was once one of the three top commercial marine fishes of China PR. Heavily exploited since the 1950s, wild stocks were so severely depleted by the 1980s that most individuals subsequently sold originated from hatcheries. After peaking at about 200 000 tonnes in the mid-1970s, catches of the croaker in China PR declined by over 90% within just 2 decades; according to most decline criteria this would categorize the croaker as ''threatened'' and management measures, including restocking, were developed. The extensive government-sponsored mariculture program introduced to address food supply and overfishing in the 1980s, particularly of the croaker, was one of the earliest for marine finfish, not only in China PR, a nation with a rich and highly successful history in aquaculture, but globally. In this first, in-depth, profile of a key fishery and early mariculture development, we integrate ecological and biological information with the fishing, management, mariculture and economic history to trace the collapse of wild stocks and assess why management and mariculture did not result in wild stock recovery. Evidence strongly suggests that a combination of heavy exploitation of spawning and over-wintering aggregations, poor management and overfishing pressure were major factors in stock declines, with contributions from pollution, habitat degradation and marine ecosystem shift. Although the croaker proved a highly successful mariculture candidate, with approximately 70 000 tonnes produced in 2005, the highest of any marine fish cultured in China PR, mariculture and restocking have failed to restore croaker stocks and may have, inadvertently, led to biodiversity losses. The detailed history of the croaker is a sobering reminder that successful mariculture, albeit important for food production and livelihoods, is not necessarily a solution to overfishing, and moreover, may have compromised fishery recovery by competing for funds, attention, space, and maybe genetic resources.

“…Simulation studies have been useful in evaluating alternative fishery management plans. For example, Huang and Walters (1983) compared alternative strategies for rehabilitation of a large yellow croaker (Pseudosciaena crocea) stock and Archibald et al (1983) estimated steady-state yields obtained from a Pacific ocean perch (Sebastes alutus) stock at different levels of fishing effort. In both studies, variability in recruitment was simulated by incorporating an error term into the stock-recruitment relationship (SRR).…”

. 1985. Comparison of constant effort harvest policies for fish stocks Environmental variability may have a substantial influence on marine fish stocks, primarily by affecting survival to the time of recruitment. Simulation studies at low, intermediate, and high levels of variability in recruitment were used to compare alternative constant effort policies for anchovy (Engraulis capensis), Atlantic menhaden (Brevoortia tyrannus), and Pacific ocean perch (Sebastes alutus) fisheries. These policies were either to maintain effort at the level producing maximum sustainable yield (fMSY), or to permit levels of effort 25-100% greater than fMsY. An increase in effort of 25% above fMsY typically did not reduce annual yield significantly; however, a significant reduction in yield was apparent in all cases when effort increased by 75-100%. When recruitment is highly variable, comparable yields may be obtained at several levels of fishing effort. In such cases, environmental variability provides the fishery manager with considerable flexibility to enhance social or economic benefits without decreasing yields significantly.La variabilite environnementale peut avoir u n e influence importante sur les stocks de poissons marins, surtout pour la survie jusqu'h I'epoque du recrutement. On a utilis6 des etudes de simulation A des niveaux de variabilite du recrutement faible, intermediaire et eleve pour comparer divers regimes d'effortconstant pour la p&che de I'anchois (€ngraulis capensis), de I'alose tyran (Brevoortia tyrannus) et du sebaste A longue machoire (Sebastes alutus). Ces regimes visaient soit le maintien de I'effort au niveau produisant un rendement maximal soutenu (fRMS) ou u n accroissement des niveaux d'effort le rendant de 25 A 100 % plus eleve que le fRMS. Un effort superieur de 25% au fRMS n'a pas abaisse le rendement annuel de facon significative ; toutefois, une baisse importante du rendement etait Cvidente dans tous les cas quand I'effort etait superieur de 75 A 100 %. Quand le recrutement est tres variable, on peut obtenir des rendements comparables A plusieurs niveaux d'effort de peche. Dans de tels cas, la variabilite environnementale procure u n e Rrande latitude au gestionnaire des pCches pour accroitre les avantages sociaux ou econowith variable recruitment. Can. J. Fish. Aquat.
