“…Such period could be coinciding with resting or developing gonads process (gametogenesis), due to no spawning activity has been confirmed (Sevilla, 1971;Vélez-Arellano et al, 2016). Also the abundance of algae (a food source for abalone) at La Bocana increases, as in nearby areas such as Punta Eugenia (Parada et al, 2009) and Santa Catalina Island (Miller and Engle, 2009).…”

“…Most indices evaluated in this study consistently showed up-down trends, with notable reductions during or on late autumn-winter period (September to February), suggesting the occurrence of spawning, and coinciding with the spawning temporality documented by Sevilla (1971) (Boolootian, 1962) , GAIA-Gonad area index, MGI-Gonadic index of calculated mass, * statistically significant correlation In spring-summer (march-august), indices showed two different trends: maintaining (IG and MGI) and increasing (GAIA and GIB). During this period, no spawning activity has been confirmed (Sevilla, 1971;Vélez-Arellano et al, 2016). In this context, the high and stable values of IG and MGI were reflecting the status of the hepatic gland-gonad complex (HGGC), due to a fat hepatic gland instead of gonad maturity.…”

The monitoring on abalone banks has been intensified since the declining of wild global production due to overfishing, disease, environmental changes and poaching. This is to support timely decisions to execute actions for mitigation, prevention, conservation and fisheries production benefits. Eight morphophysiological indices for green abalone, Haliotis fulgens Philippi, 1845 from the Pacific coast of Mexico were evaluated and their performance were elucidated due to their potential as monitoring tools. The Boolootian's gonadic index (GIB) and gonadic area index (GAIA) were informative of complete reproductive cycle, thus are reliable for reproductive patterns monitoring. While gonadic index (GI) and gonadic index of calculated mass (MGI) were suitable indicators only of spawning. The condition index of calculated mass (MCI), foot index of calculated mass (MFI), condition index (CI) and foot index (FI) proved temporal changes of soft tissues condition. The MFI clearly defined the best nutritional status of the green abalone foot between March to August, indicating the time when fishing organizations can get the best yields and highest foot quality at Baja California Peninsula, Mexico.Therefore MFI can be used as cheap and quick information to make decisions on the start-up of fishing operations and abalone condition monitoring.
